demonstrates the main activities of the target operation and the relations between

each activity. The general procedures of diving and positioning activities are attached

to this document. The sequences of work when the vessel at location shall be as

follows:

7.6.1. Locating the Crossing Point

As the first step of installation activity, and based on positioning team instruction, the

vessel takes position on top of the crossing point defined and provided by the client.

7.6.2. Crossing Point Verification

After positioning the vessel on top of the crossing point, diver will check the exact

position of existing pipe line by using beacon and assist of sector scan sonar. If diver

couldn’t find the existing pipe or cable a visual survey will carry out in the range of 20

meter. This data will be sent to the surface and positioning team compares it with

client data. In case of any nonconformity the operation will be held on standby for

client instruction. During the verification, positioning team will record two coordinates

on pipeline and use these coordinates as reference to recheck the position of

pipeline.

7.6.3. Transfer the Mattresses to the Deck of Installation Vessel

After verification of the crossing final coordinate the installation vessel will go along

side of transportation vessel and by using on board cranes transfers mattresses to

installation vessel deck. It should be noted that the first mattress must have rubber to

prevent any damage to pipeline

FE560 GEXP PL PR 1727 D0

7.6.4. Installation of Positioning Equipment

The positioning equipment will set up on a lifting frame prior to the lifting. This

equipment contains two compatts in each side of the frame. By using these two

compatts surveyors will be able to locate the exact coordinate of crossing point and

match it with the proposed coordinate.

7.6.5. Installation of Rigging Items

Riggers will install the mattress lifting frame by connecting the side lifting ropes to the

frame and secure the pins. On the other side the frame will be connected to the

crane hook with 4 wire slings and will be prepared for lifting. The arrangement is

shown in attachment 8

7.6.6. Vessel Positioning On Mattress Installation Coordinates

Positioning team will lead vessel to the coordinates, which has been adjusted

according to crane geometry on the vessel and sea bed position of the crossing. In

this way when the vessel stands on this position, the mattress will be lowered down

directly to the final installation position.

7.6.7. Lifting and Lowering the Mattress

After confirmation of the vessel position by surveyors, lifting operation will start under

supervision of the superintendent. In this part the mattress will lift off from deck and

smoothly guided to the lowering position. Mattress will lower down to the sea bed up

to 1.5 meter above the sea bed. The surveying team will assist superintendent, using

sector scan sonar and LUSBL to monitor lowering operation real time. This device

will show the relative position of the support and the existing pipe line. Meanwhile

diver will monitor the arrival of mattress on sea bed and assist superintendent to start

the next level of operation.

7.6.8. Lead the Mattress to the Exact Coordinates on Seabed

In this stage diver will adjust mattress position and orientation with instructions he

receives from the superintendent and the surveyor on surface. Again LUSBL system

gives the exact coordinates and sector scan sonar visually shows the situation. After

final check and confirmation of the position by surveyors, support will lower down to

the sea bed.

7.6.9. Detach Installation Equipment

By completion of the previous stage of operation the load will be released from crane

and diver proceed to detach mattress from the frame. Also, the positioning

equipment will be released and recovered to the surface.

7.6.10. Continue Installation of Other Mattress

Considering the fact that most crossing location consist more than one mattress, the

above operation has to be repeated for each support.

7.6.11. Perform Final Diver Visual Survey for Crossing Location

The final visual check after completion of installation will be performed to prepare a

video report.

7.6.12. Preparation of Installation Reports

Different types of reports will be prepared during installation, detail information of

each report provided in attached procedures. These reports comprise daily progress,

activity completion or data confirmation.

7.6.13. Proceed to the Next Crossing Location

After completion of the surveys and approval of the installation condition by client,

the installation vessel will shift to the next crossing location. Obviously above steps

will be repeated until the whole project scope of work accomplished satisfactorily.

2.4 EXTERNAL CERTIFICATION AND DOCUMENTATION

FLXMAT is made from 3 main components (HDPE Mould, PP Rope and Concrete). Rope Mill Test Certification is very important so that International Grout Operations Engineers can verify the correct rope has been used according to DNV Pt2, Ch5. Polypropylene Rope is purchased specifically for each project from an approved vendor. Similarly, concrete is purchased and delivered onsite by preferred supplier. Delivery dockets are collect by the supervisor and recorded. Concrete compressive strength tests are conducted at vendor’s laboratory. Final results from laboratory tests are sent to International Grout Operations and filled accordingly. The following summarises relevant external documents

4.0 FLXMAT MANUFACTURE ACTIVITIES

4.1 PRE-EXECUTION ACTIVITES

Prior to the execution program the final design and price is agreed upon and a purchase order is received by International Grout Operations outlining a date for completion or mattress delivery. The project manager will then organise freight of components (if necessary) schedule a starting date. An experienced supervisor is nominated and sent to location for site establishment. Work will continue to finalise all relevant documentation necessary to commence work according to International Grout Operations quality procedure.

Page 55: Installation Crossing Procedure for Export Pipeline With Attachments

Execution Plan

                                                                                                                           Page: 5 

4.2 SITE ESTABLISHMENT

Upon the supervisor arriving to site a project brief is given from the project manager outlining the scope of works. All approved documentation is given to the supervisor in order to commence the fabrication according to this Execution Plan. The supervisor will firstly check all stock numbers of shells, clips and rope to ensure there are enough quantities of each to complete the order. If the quantities are incorrect the Supervisor will alert the Project Manager immediately to rectify the situation. The supervisor should have the following items in mind when initially setting up site. Suitable area for FLXMAT Assembly

o Select shaded or enclosed area if possible (avoids heat exhaustion) o Select high ground is possible (avoids potential flooding, which is uncomfortable to staff) o Enable forklift entrance/exit if possible (reduces heavy man handling of objects)

Suitable area for FLXMAT Casting

o Fall of land when considering flooding (water must run away from work area) o Monitor unsettled dust during windy conditions (risk of eye injury to staff) o Avoid any rocky outcrop or remove if possible (reduces the risk of trip hazards) o Sufficient room for concrete trucks entering/exiting site (traffic management and safety)

4.3 FLXMAT ASSEMBLY

Following points refer to assembling each mattress up until casting.

1. FLXMAT shells are laid out and clipped together either on ground level or on specially built clipping tables.

2. The bottom half of the mattress is clipped together until the length and width match that of the construction drawing.

Page 56: Installation Crossing Procedure for Export Pipeline With Attachments

Execution Plan

                                                                                                                           Page: 6 

3. Lateral and longitudinal ropes are pre-cut to determined length as noted on the construction drawing.

4. Lateral and longitudinal ropes are installed throughout the bottom half of the clipped mattress according the roping detail shown on construction drawing.

5. Lifting ropes are set to designed length as

per construction drawing. Perimeter top shells are fastened first in order to contain rope lattice.

6. Rope ends are terminated using an open splice which should always be positioned toward the centre of the mattress and centre of shell. If design includes edge lift ropes then these should be installed as per instruction noted on mattress construction drawing.

7. Once all longitudinal and lateral ropes are tight remaining central blocks are clipped together to complete the mattress. Shells must be positioned carefully to locate each clip’s top half ensuring a positive connection.

8. The mattress is then lifted and relocated to the casting area via folk lift or a team of men. The mattress is carefully positioned on polythene sheet. The newly laid mattress is inspected and undergoes QR1 (Quality Record 1). QR1 is a set of quality checks required to be carried out prior to casting each mattress. On approval of QR1 the assembled mattress is clearly marked according to Section 5.4.

Execution Plan

                                                                                                                           Page: 7 

4.4 FLXMAT CASTING

1. Concrete is ordered by Supervisor ensuring the correct mix design is conveyed to the nominated

vendor. The quantity is calculated based on the number of empty mattresses anticipated to be cast.

2. The concreting team prepare the initial casting location with shovels, trowels, vibrators, wheelbarrows, shadow boards and buckets.

3. The concrete truck is directed to drive alongside the assembled mattresses with chute full extended to aid filling distant blocks. The shadow boards mask all areas not requiring concrete guiding flow directly into each block.

4. Each mattress block is vibrated until full and no additional settlement is noticed.

5. Shadow boards are continually relocated as the process moves forward allowing the finishing team

to trowel off the newly filled mattress and wash down any excess concrete. Lifting rope shall be washed free of any concrete spillage.

6. The mattress should be allowed to cure for a minimum of 3 days prior to lifting or confirmation of min. 14 MPa strength.

                                                                                                                           Page: 8 

4.5 FLXMAT STORAGE AND HANDLING

1. Mattresses are only lifted with a suitable lifting frame of known capacity. Prior to lifting the

supervisor will check with International Grout Operations Engineering that nominated frame and rigging is suitable to lift cured mattresses.

4.6 ONSITE SAFETY REQUIREMENTS

All personnel shall attend any required site induction program to become familiar with the site and client method of operation. Personnel shall comply with all client rules and regulations. Company equipment includes a comprehensive first aid kit. Personnel will be briefed during the initial site induction on the hazards of manufacturing FLXMAT and handling cement products. The IGO supervisor will be responsible for site safety and conduct regular toolbox meetings with all personnel The following PPE (Personal Protective Equipment) is required for the 3 Manufacturing activities outlined above.

6.0 INSPECTION AND REPAIR PROCEDURE During assembly of the mattresses all shells and clips are inspected for faults. If a shell has any cracks or is deficient they are immediately discarded, and similarly clips are discarded if they are deficient. Any clips that are not holding shells together satisfactorily are reinforced with screws. After casting all mattresses are inspected by the International Grout Operations site supervisor and the inspection details are recorded within QR1. The mattresses are checked for any casting deficiencies that may compromise integrity. If after curing the mattress integrity is found to be affected or faults exist that impinge safe handling or risk mattress longevity, it will be discarded immediately.

Introduction:The following calculations assess the mattress rope MBL for offshore lifting and are completed in accordance with DNVRules for Planning and Execution of Marine Operations (1996) - Part 5&6

Variables: RemarkLoad Factor [γf] Assume 1.3

Consequence Factor [γc] Assumed 1.3 whereby sling failure would not incur a total loss

Splicing/Bending Factor [γr] Assumed 1.0 when splice consumed in concrete block

Wear Factor [γw] Assume 1.0

Material Factor [γm] Assume 3.0 for fibrous rope

Maximum Breaking Load [MBLActual] Actual Maximum Breaking Load of the rope supplied

Methodology:The minimum required MBL is calculated by the following:

MBL required = Maximum Dynamic Rope Load x Nominal Safety FactorMaximum Dynamic Rope Load is back calculated from rope properties and lift geometry

Dynamic load = (Mattress mass [MT] x DAF x Skew load)

Nominal Safety Factor [γst]

- γ st = γ c .γ r .γ w .γ m .γ f

Finally for the lifting rope to be safe the following equation must be satisfied

SAT DHRUV 3 12 MEN Saturation Diving System Specification

General Description The saturation diving system is of modular construction, meaning that the major components of the diving system are built into individual crash frames which will also allow the system to be configured in different configurations to make maximum use of the space available on the barge or proposed dive ship. The saturation diving complex and associated equipment is capable of supporting a 12 man diving team in 1 x 4 plus, 1 x 3 man bunk &12 sitting HRC & 1 x 6 men chambers to a maximum working depth of 200 meters. The design and certification for the diving system will be for a maximum design pressure of 200 meters. The diving bell will be equipped for three divers. It will be used for saturation mode only. The bell has one side mating position. The bell will be handled by a simple ‘A’ Frame assembly, with two hydraulic rams and the trolley will bring the bell in to the side mating position. For deployment, the bell will be trolley out and will be hoisted in to the catcher deployment system, the ‘A’ Frame will be boomed out to the launch position. The handling system for the bell will also incorporate a hydraulic bell winch and a Hydraulic driven clump weight winch. The hydraulic main bell winch will be the primary means of recovery and deployment. This will use the hydraulic motor as the primary means of operating the winch and the air motor will be the secondary means of operating the winch and the clump weight winch will act as another means of recovery. The operation of the hydraulic handling system and winches will be from the hydraulic control consul, which is situated on top of the living chamber (DDC 013) Skid package.

1.5. Survey Line Plan

1.5.1. Pre-Installation Survey Prior to installation a single MBES line is to be run to confirm the position of the existing pipelines. This line will be parallel to the pipeline and the length of the line will be a minimum of 50 m. If there is a group of crossings, a single MBES line will be run to combine these locations.

1.5.2. As-Built Survey A 50 m x 50 m survey is to be conducted, centred on the as-built position of the mattress supports. Table 5 states the line plan requirements.

Survey Line Plan

Lines Line Spacing (m) Number of Lines Orientation

Main Lines 50 2 Parallel to pipeline

Cross Lines n/a 1 Perpendicular to pipeline

Table 5: Survey Line Plan

The boundary coordinates are to be calculated by the PC, based on the as-installed position of the mattress support.

Note:

As 100% coverage is required, the line spacing may be reduced in shallow water depths. On the other hand the line spacing in deeper areas can be increased based on the actual acquisition from the MBES and water depths. Both actions can be decided in the field by the Party Chief and client representative. The survey lines shall be terminated / diverted when approaching existing structures.

Table 6: Equipment Onboard DP 'Gerimal'

During mobilisation all calibrations and verifications (in accordance with Appendix D) will be conducted prior to the commencement of any work. The verifications, calibrations and checks to be completed during mobilisation and in the field prior to the start of survey operations are as follows:

• All vessel and sensor offset measurements. • DGPS verification - primary and secondary positioning systems. • Gyro alignment calibration. • CTDS wet test • USBL calibration. • Velocity cast. • Transit check. • Draft measurement for underwater sensors (MBES & USBL transducers). • MBES patch test calibration.

The geodetic computation check shall be cross checked (coordinate transformations) and shall be signed off by the PC and the Client/representative. The geodetic parameters and the QINSY setup parameters are to be transmitted to the office for verification PM and SM.

2.2. Geodetic References, Datums and Tidal Reduction

2.2.1. Geodetic References The primary grid coordinate system to be adopted is the ITRF 2000 to epoch 1997.0 reference system as follows:

• Spheroid name : WGS84 • Datum name : ITRF 2000 to epoch 1997.0 • Projection name : Universal Transverse Mercator: (UTM) Zone 39N.

Note:

If any of the verifications/calibrations are unable to be conducted during mobilisation or prior to the vessel sailing, the client, PM and SM must be informed.

Page 96: Installation Crossing Procedure for Export Pipeline With Attachments

Page: 7 CP-SPE-0566A - Survey Quality Plan - Rev 0

Refer to Appendix C for geodetic details parameters and geodetic computation check.

2.2.2. Vertical Datum All offshore elevations and bathymetry will be referenced to L.A.T.

2.2.3. Tidal Reduction All bathymetric data acquired during the survey will be reduced to the L.A.T. by the simplified harmonic method of tidal prediction. The harmonics and tidal constituents for the survey area were derived from the Admiralty Co-tidal Atlas for the Persian Gulf, NP 214 (refer to Appendix C for details).

2.3. Vessel Offsets, Horizontal and Height References

2.3.1. Horizontal Reference The CRP from which all offsets are to be measured is the primary C-Nav antenna which will where practically possible be located above the vessel bridge on the fore and aft centreline of the vessel. All offsets will be measured using land survey techniques and verified with tape measure during mobilisation. All measurements will be reduced logged and entered into the navigation system and verified by the surveyor / PC.

2.3.2. Vertical Vessel Reference Height references will be related to the main deck level adjacent to the MBES pole. The vertical reference for all sensors is variable based on the vessel draught and freeboard to the main deck. The draught measurement shall be recorded at the following times:

• Upon the completion of mobilisation before leaving the port. • Any time the vessel is alongside. • Any time the vessel takes on fuel or water.

The draught measurements are to be logged and provided to the CAD processors onboard.

2.4. Field Operations Prior to sailing to site, the surveyor will complete the Personnel Responsibilities and Survey Procedures Awareness form located at the front of this procedures document. This form along with the survey system configuration printout should be faxed back to the Survey Department for checking and approval. Data is to be recorded within QINSy database files throughout the project operations, this is includes (but not limited to) the diving operations. Positioning of the vessel is to be recorded in QINSy on a 24 hour basis while the vessel is in the field. These QINSy database files are to be submitted to the client at the end of the project.

Note:

Regular draught readings are to be conducted and recorded in the log book and offsets are to be applied in all relevant software during acquisition. Any discrepancy of observed data must be brought to the attention of the PC onboard and investigated. Any doubt on the validity of the data must be communicated to the PM and SM.

Page 97: Installation Crossing Procedure for Export Pipeline With Attachments

Page: 8 CP-SPE-0566A - Survey Quality Plan - Rev 0

To accurately position the supports during installation, surface and subsurface positioning systems will be used as follows:

2.4.1. Pre-Installation MBES Survey Prior to installation a MBES line is to be run to confirm the position of the existing pipelines against the client supplied information. If the pipeline is within tolerance (±2 m) verbal confirmation can be given to the client for approval. If the positions of the pipelines DO NOT match within tolerance (±2 m), a field report will be created and approved by the client. Once client approval is obtained, the mattress installation can commence.

2.4.2. Surface Positioning The DP 'Gerimal' will accurately setup over each of the support installation positions, the mattress supports will be lifted and deployed using the DP 'Gerimal' supplied crane wire / frame. Two fixed offsets for both mattress support ends should be accurately measured by the survey crew and added to the positioning and navigation system. Prior to the mattress support deployment, a DGPS position logging will be undertaken to determine the deployment position and heading. The mean position and heading will be calculated upon completion of the logging session.

A dedicated subsea gyro, mounted on a temporary support on the mattress and aligned with the mattress’s axis, shall provide the mattress heading and inclination (pitch/roll). A CNAV system is to be installed on the crane boom to monitor the position of the crane head at all times. Screen shots for the deployment position and heading of the mattress supports on the navigation display should be recorded.

2.4.3. Underwater Positioning The DP 'Gerimal' will accurately setup over each of the support installation positions; prior to installation a MBES line will be run to confirm the position of the existing pipelines within the tolerance stated above in the Section 2.4.1. To provide a continued relative measurement between the mattress and the existing pipeline two USBL beacons are to be installed onto the existing pipeline. As a simultaneous independent positioning system, two (2) USBL beacons will be installed, two at opposite ends of the mattress support to monitor its position while being lowered to the seabed. An underwater gyro will be installed on the mattress to provide heading and inclination (pitch / roll). Once on the seabed, logging of position fixes for a minimum of 15 minutes will be acquired to determine the as installed position and heading of the mattress support. Mean position, heading and inclination will be calculated upon completion of the logging session of both surface and underwater positioning systems. Upon client acceptance of the final position, heading and inclination (pitch / roll), the USBL beacons and underwater gyro will be recovered by the divers, and the as-built position will be observed using MBES.

2.4.4. Sector Scan Sonar A sector scan sonar is to be deployed during the mattress installation. This will provide a real-time visual observation of the installation. When the mattress support is lowered to the seabed, the distance of the mattress with respect to the existing pipeline is to be measured. A screen shot is to be taken and included as part of the mattress installation report.

2.4.5. As-Built MBES Survey

Upon completion of installation of the group of mattresses, a MBES as-built survey is to be conducted to observe the as-built position of the mattress support, in accordance with section 1.5. The PC will advise

Page 98: Installation Crossing Procedure for Export Pipeline With Attachments

Page: 9 CP-SPE-0566A - Survey Quality Plan - Rev 0

the client on the best line plan for achieving the required results and reducing potential infill work. Any deviation from the stated plan must be recorded in a variation and transmitted to the PM and the SM.

2.4.5.1. On-Line Navigation and Acquisition Systems The on-line navigation and acquisition systems (QINSy,) will be setup to comply with the following criteria as a minimum:

• Date, time and position tagging. • Sampling and computation of all positioning system data. • The cycle time shall not exceed 2 seconds. • Processing and real time display of sensor data. • QC and verification of data (with hardcopies printouts of non-conforming events/data). • Logging of all raw data acquired from the various sensors.

2.4.5.2. Off-Line Processing Systems

The off-line processing and charting systems (QINSy, AutoCAD, CARIS etc) shall be used to provide an accurate and complete output from the survey data acquired. In addition to data processing and merging systems, charting systems, standard word-processing and spreadsheet programs, the onboard software programs will be capable to provide the following:

• Geodetic transformations. • Tidal computations. • Reduction of bathymetric data for tides. • VoS computations. • Editing, approved smoothing and merging routines. • Re-computation of surface positioning data from raw data.

2.4.6. Bathymetric Acquisition

The bathymetric survey shall be conducted utilising MBES system. A motion sensor will be interfaced to the MBES to compensate for heave, pitch and roll effects. All data shall be digitally recorded for processing. Acquired data digitally logged using QINSy system, will be analysed after processing by the geophysicist, who will produce a detailed report describing the seafloor bathymetric information within the survey limit. The report will be illustrated with bathymetry images of the crossing locations.

2.5. Real Time QC Monitoring The following sensor information will be displayed in a time series plot on the online navigation computer which will be continuously monitored by the online surveyor:

• Primary positioning system. • Secondary positioning system • Sensor updates rates.

The following sensor data will be shown in a time series window for real time comparison:

• Comparison between primary and secondary positioning systems. • Comparison between the surface and underwater positioning systems.

5.3. Drug and Alcohol Abuse Policy

HSC takes drug and alcohol abuse as a serious matter and will not tolerate it. HSC absolutely prohibits the use of alcohol or non-prescribed drugs at the work place or while on company premises. It also discourages non-work place drug and alcohol abuse. The use, sale or possession of alcohol or non-prescription drugs while on the job or on company property may result in immediate suspension or discharge. HSC reserves the right to demand a drug or alcohol test of any employee based upon reasonable suspicion. Reasonable suspicion includes, but is not limited to, physical evidence of use, involvement in an accident, or a substantial drop off in work performance. Failure to take a requested test may lead to discipline, including possible termination. HSC also cautions against use of prescribed or over-the-counter medication which can affect your work place performance. You may be suspended or discharged if the company concludes that you cannot perform your job properly or safely because of using over-the-counter or prescribed medication. Please inform your supervisor prior to working under the influence of a prescribed or over-the-counter medication which may affect your performance. HSC will make every effort to assist its employees who wish to seek treatment or rehabilitation for drug or alcohol dependency. HSC will consider continued employment of such an employee as long as the employee adequately addresses continued concerns regarding safety, health, production, communication or other work related matters. You may also be required to agree to random testing.

5.4. Stop Work Policy HSC believes that all accidents are preventable and empowers all employees, contractors, clients and guests to:

• Stop any job if they believe that it may cause harm to people the environment or assets. • Refrain from actions that are considered a threat to HSE. • Contact line managers in a culture of openness and trust to advise of any safety concerns that

they have with regards operations they are involved in.

All HSC staff and contractors have a duty to stop any operation if to ensure that the health and safety of all colleagues is maintained at all times. Failure to stop an operation that is believed to be unsafe may make the individual culpable in the event of future investigations.

www.horizonsurvey.ae

The new Meridian has been designed to be the smallest, lightest, most flexible and accurate mechanical gyrocompass available to commercial users. The new Meridian Surveyor boasts a wide range of interfaces to enable use on any marine vessel. The unit utilises a DTG gyro element which provides exceptional performance with accuracy unmatched by even the latest fibre optic designs. Unlike conventional spinning mass gyrocompasses, the Meridian Surveyor uses a dry tuned element (DTG) that removes the need for routine maintenance thereby significantly reducing cost of ownership. Hence the Meridian Surveyor provides reliable, maintenance free operation with an MTBF in excess of 30,000 hrs.

Survey Configuration Created at the planning stage with the Setup program, a Template Database contains all survey configuration parameters pertinent to the project. QINSy supports most of the datums, projections, US State Planes, units and geoidal models used world-wide. The template contains vessel shapes, administrative information, as well as vessel offsets and I/O parameters. It is a complete reflection of your current survey set-up, and fully editable to kick-start your next project. Background display Drawing files generated from CAD programs often contain more recent and accurate information than electronic charts. To ensure speedy refresh rates of real-time displays, these files are converted with the DXF Converter to a binary format at the planning phase for subsequent online display as an overlay to ENC data in the Navigation Display. Real-time Final Results - Data Collection and Output Raw Sensor Data All raw sensor data is logged and permanently stored in a fast relational database (*.db) to which the entire survey configuration is copied from the template. Raw data can be analysed and edited using the Analyse program, making it ready for the Replay program and generation of new results if that is necessary. Results data (X,Y, Z and attributes) is stored to one of several formats, primarily the QPS internal format (*.qpd), but also to ASCII, FAU or Helical SDS f ormat. Data Storage How raw and results data files are split up during acquisition is your choice. Data may be stored on a line-by-line basis, by file size, or by manual intervention. Whatever the method, data is normally stored in several separate databases for convenience in processing. Accurate Timing and Ring Buffers Supremely accurate timing is imperative in many survey situations. QINSy uses a very sophisticated timing routine based on the PPS option (Pulse Per Second) available on almost all GPS receivers. All incoming and outgoing data is accurately time stamped with a UTC time label. Internally, QINSy uses so-called “observation ring buffers”, so that data values may be interpolated for the exact moment of the event or ping. Real-time DTM Production All computations of position are performed in 3D. In combination with RTK or real-time tide sensors, this means that all depth observations are immediately available in absolute survey datum coordinates. This unique technique is called “onthe-fly DTM Production”. QPS was the first company introducing the “delta heave” method, which means that the quality of the final DTM is not longer affected by heave drift caused by vessel turns. Advanced Gridding Methods For multibeam surveys,“gridding” is the predominant data reduction method. However, achieved reduction usually comes at the cost of loss of resolution. In QINSy 8,QPS introduces 2 new gridding methods, namely; 1. An irregular gridding method in which the size of cells created in real-time is directly related to variation of

the seafloor. In general, large cells, more appropriately called tiles, are created in flat seabed conditions and small tiles created in feature rich areas with slopes, wrecks, rocks, and sand ripples. This on-thefly method effectively reduces the volume of data without loss of resolution.

2. A regular multi-level gridding method. Based on the minimum cell size, 5 additional grids are generated

on-the-fly. Grid file size is no longer an issue, since there is no limit to the number of grid cells. If the minimum cell size is selected to be 1 x 1 meter, then automatically the following grid levels are being generated: � 2 x 2 � 4 x 4 � 8 x 8 � 16 x 16 � 64 x 64 being the overview level

Page 117: Installation Crossing Procedure for Export Pipeline With Attachments

Software – Qinsy 8

www.horizonsurvey.ae

This grid can be used not only for bathymetry, but also for SSS Mosaicing, magnetometerdata, seabed classifications, etc. Both methods provide maximum flexibility in data acquisition since there is no longer any need to pre-define grid boundaries. XYZ Data Reduced point data output to tiles is accompanied in parallel with output of aall soundings to a second file (*.qpd, *.sds, *.fau, *.pts or other). Either reduced or full datasets are available for further DTM processing. Side Scan Sonar Snippets Full 3D geo-referenced Side Scan Sonar data, called “snippets” is available from most modern SSS and multibeam sensors. This geo-referenced SSS data, and/or data from dedicated side scan sonar sensors, is presented in real-time as a mosaic in the multi-layered QINSy Navigation Display. QINSy offers advanced real-time SSS target detection, which means a that SSS processing time is almost cut down to zero. A dedicated SSS data viewer allows you to load, view SSS data and perform target detection in just seconds. Eventing Used in many survey operations like for example pipe-laying, pipeline inspection, and buoy tendering, eventing is a powerful feature in QINSy 8. Using the Event Tablet, events are easily generated with a single mouse click, with an event log stored in real-time. Advanced Dredging Functionality QINSy adds advanced dredging functionality to speed up and control the quality of dredging operations in real-time. The various layers are presented in longitudinal and cross-section views, the latter being dynamically updated based on object heading. The entire dredge process is monitored via the groundbreaking real-time 3D display, employing multiple perspectives from different camera views. If available as 3DS files, objects like dredge heads and hopper dredgers are seen moving in a virtual 3D environment at the same time that the dredged depths are updated in the 3D grid, all in real-time.

Speedy Processing - Data Validation, Editing, Calibration and Tide Reduction Data Cleaning and Filtering Applying various filters and corrections for motion, tide and refraction, QINSy is designed to output almost final results at the time of data acquisition. Moreover, the many quality assurance functions equip the surveyor with tools to qualify results data in real-time. Starting with cleaner and thinned data, effectively reduces time spent in post processing. XYZ Attributes All X, Y, Z and attributes are stored during data acquisition in a fast database, with the following attributes attached to each point: • Identification (vessel name, system type, ping number, beam number, etc.) • Status (accepted, rejected, filtered, manually edit, etc.) • Backscatter • Full 3D Geo-Referenced Side Scan Sonar (Snippet) • User Defined On-line Flags • Quality Parameters The QINSy Processing Manager All XYZ files are listed in the QINSy Processing Manager, tabulated against a history of processes performed on each file. This provides a complete overview of the project processing status. Processing programs are launched from the Processing Manager: • The Tide Definition and Processing utility supports various methods for tidal reduction. • The Validator supports both manual and automated data cleaning including advanced 3D splined surface cleaning. The QINSy Validator Multibeam exploded the volume of point data and created data handling challenges both at the acquisition and processing phases. The QINSy Validator is probably the most powerful data-cleaning program on the market today. Inherently fast data access allows loading and viewing of millions of points in just seconds. The Validator has 4 different views, 3 of which can be opened simultaneously: • Plan View • Cross View • Profile View • 3D View Multibeam Calibration Multibeam calibration with QINSy is inter-active and very easy. The Validator offers tools to calibrate for errors in: • Roll • Pith • Yaw • Timing

Singlebeam and Multibeam Data Editing Editing of singlebeam or multibeam data has never been easier. A variety of automated cleaning algorithms are available: • Apply On-line Flags • Clip Below / Clip Above • Adaptive Clipping • Median and Mean • Butterworth • 3D Spline Surface Despiker • Multiply/Shift The Validator adds fully automated pipeline detection features, such as: • Top of Pipe Detection • Bottom of Trench • Mean Seabed Detection Powerful Side Scan Sonar Functionality Side Scan Sonar data is viewed and processed with the Side Scan Sonar Viewer program. It offers the same look and feel as the SSS Display which is used during data acquisition. Powerful target detection tools allow you to export targets and GeoTIFF images (georeferenced bitmaps) to the QINSy Mapping database to provide a complete targets overview. Eye-Catching Products – DTMs, Profiles, Volumes, Chart Production and ENC’s

MBE – Kongsberg EM3002

www.horizonsurvey.ae

The EM 3002 is a new advanced multibeam echo sounder with extremely high resolution and dynamically focused beams. It is very well suited for detailed seafloor mapping and inspection with water depths from less than 1 meter up to typically 150 meters in the ocean. Maximum depth capability is strongly dependant on water temperature and salinity, up to 300 meters is possible under favorable conditions. Due to its electronic pitch compensation system and roll stabilized beams, the system performance is stable also in foul weather conditions. The spacing between soundings as well as the acoustic footprints can be set nearly constant over the swath in order to provide a uniform and high detection and mapping performance. Dynamic focusing of all receive beams optimizes the system performance and resolution for short range applications such as underwater inspections.

Typical Applications

• Mapping of harbours, inland waterways and shipping channels with critical keel clearance • Inspection of underwater infrastructure • Detection and mapping of debris and other underwater objects • Detailed surveys related to underwater construction work or dredging • Environmental seabed and habitat mapping • Mapping of biomass in the water column

Features

• The EM 3002 system uses one of three available frequencies in the 300 kHz band. This is an ideal frequency for shallow water applications, as the high frequency ensures narrow beams with small physical dimensions. At the same time, 300 kHz secures a high maximum range capability and robustness under conditions with high contents of particles in the water.

• EM 3002 uses a new and very powerful sonar processor in combination with the same sonar head used with the

popular and highly acclaimed EM 3000 system. The increase in processing power makes it possible to apply sophisticated and exact signal processing algorithms for beamforming, beam stabilisation, and bottom detection. The bottom detection algorithm is capable of extracting and processing the signals from only a part of each beam, thus making it possible to obtain independent soundings even when beams are overlapping.

• EM 3002 will in addition to bathymetric soundings, produce an acoustic image of the seabed. The image is

obtained by combining the acoustic return signals inside each beam, thus improving signal to noise ratio considerably, as well as eliminating several artifacts related to conventional sidescan sonars. The acoustic image is compensated for the transmission source level, receiver sensitivity and signal attenuation in the water column, so that reliable bottom backscatter levels in dB are obtained.

• The acoustic seabed image is compensated for acoustic raybending and thus completely geo-referenced, so that

preparation of a sonar mosaic for a survey area based upon data from several survey lines is easy. Objects observed on the seabed image are correctly located and their positions can be readily derived.

Operator Station

• The Operator Station is a ruggedized PC workstation running on either Linux® or Microsoft Windows XP®. The Operator Station software, SIS, has been completely redesigned and expanded compared to the EM 3000 software, adding 3D graphics, real-time data cleaning and electronic map background.

• The EM 3002 can be set up to use other operational software than SIS, for example QPS “QINCy” or Coastal

Oceanographics “HYPACK Max”, and is also supported by software from Triton Elics International, EIVA and others.

SSS – GeoAcoustic Dual Frequency

www.horizonsurvey.ae

The GeoAcoustics Dual Frequency Side Scan Sonar system is the ideal tool for seabed feature mapping, offering flexibility and high quality results in a simple and reliable package. The system offers high resolution, switch selectable, dual frequency operation (114/410 kHz), which when combined with multiplexed data transmission enables a low drag co-axial tow cable to be used. The modular design of the system makes it ideal for combining with our GeoChirp and GeoPulse sub-bottom profilers. The versatility, ease of operation and cost effectiveness of the system has made it a popular choice with commercial survey companies. Standard System The standard system employs a lightweight towfish, which is easily deployed by one person and can operate to a depth of 1000 metres. There are separate controls for each channel, which makes the system very easy to operate. The basic system includes the following:

Transceiver (Model SS981) Towfish (Model 159D), which houses the Multiplexer (Model SS982) and Two Dual Frequency Transducers (Model 196D/Port and Starboard).

Transceiver The transceiver unit allows the operator a simple means of controlling various Side Scan operating parameters. The unit includes standard controls such as: Gain, Time Varying Gain (TVG) and Automatic Gain Control (AGC), with duplicated controls for Port and Starboard channels. The operating frequency can also be switched from 114 kHz to 410 kHz directly from the Transceiver. The choice of frequencies means that long range scanning and short range high resolution investigations are both possible. Multiplexer The Multiplexer Unit (SS982) is the sub sea processing section of the Side Scan Sonar System. The SS982 is mounted in the tail of the towfish, on the tail of a combined towfish or on an ROV, as required. The use of standard sub-sea connectors throughout allows easy installation in all situations. The SS982 includes all of the transmitter and multiplexing electronics, thereby ensuring that transmission power is not lost in the towcable and also reducing the risk of high voltage defects. The multiplexed data transmission technique employed allows the system to be used with a wide selection of towcables, including twisted pair and co-axial cables. Data from the Dual Frequency Side Scan Sonar can be input to many sonar processing systems, including the GeoPro Sonar Processor, or it can be displayed on a wide variety of industry standard graphic recorders. The multiplexed data offers a resolution equivalent to a 16 bit analogue to digital converter operating at 50k samples/sec per channel, when used with short towcables.

APPENDIX D – SYSTEM VERIFICATIONS & CALIBRATIONS

Page 138: Installation Crossing Procedure for Export Pipeline With Attachments

Page: 28 CP-SPE-0566A - Survey Quality Plan - Rev 0

SYSTEM VERIFICATIONS Prior to the survey acquisition, a number of system verifications and checks should be carried out during the mobilisation stage in port and later in field to ensure that all systems are operational and working according to the planned operating parameters and tolerances. In-Port Verifications The following verification and checks must be carried out during the mobilisation stage and prior to the vessel sailing to site.

The verifications, calibrations and checks to be conducted in-port are:

• Vessel offset measurements. • DGPS verification for primary and secondary positioning systems. • Gyro alignment calibration. • Static USBL Calibration • Draft measurement for underwater sensors (USBL and MBES transducer, etc). • Water height measurement for height reference. • Wet and acquisition testing for all survey sensors.

- Vessel Offset Measurements The C-Nav antenna should be the designated as the Common Reference Point (CRP) for the horizontal control on the vessel. All offsets of different navigation and survey sensors are to be measured to the primary C-Nav antenna, which has to be located (if applicable) above the bridge on the centreline of the vessel. All offsets to be measured using land survey techniques during vessl mobilisations and to be independently rechecked manually using measure tapes. The acquired measurements should be reduced, logged, entered to the navigation system and provided to the project survey data processors onboard. - Static DGPS Health Verification A DGPS health verification should be carried out in port prior to the vessel sailing. The DGPS health verification should be carried out for both primary and secondary DGPS systems independently. There are three different methods to carry out the verification. Method 1: Set up the GPS antenna over a well known land control station in the port and the received DGPS positioning data to be logged for a period of at least 60 minutes. The mean position value derived should be compared against the known position of the land control station. If it is not possible to locate the GPS antenna over a land control station, X & Y offsets should be measured from the land control station to the antenna. The comparison should take the physical offset between the land control station and the antenna into consideration. Method 2: Utilise land survey techniques, by setting up the total station over a nearby land control station, to carry out set of observations to the GPS antenna accompanied with simultaneous logging for the DGPS position data. The results of both survey sessions should be reduced based on the time of each land observation, the mean values to be calculated and compared against each other.

Note:

If one or more of the following verification/checks are unable to be conducted prior to the vessel sailing the Survey and Project Managers must be contacted and informed to replace it with alternate verification/check. All positional related calibrations (DGPS, Transit Fix, etc), should be carried using PPS mode.

Diagram 2: DGPS Verification Diagram, First Method

Diagram 3: DGPS Verification Diagram, Second Method

Method 3: Compare the position of both primary and secondary DGPS systems against each other. In this method, a simultaneous logging session for the DGPS positioning data for both primary and secondary GPS antennas should be recorded for a period of at least 60 minutes. The derived position values should be reduced and compared against each other considering the physical distance between the two antennas.

Diagram 4: DGPS Verification Diagram, Third Method

Note:

During this method, the surveyor should make sure to enable the differential GPS (DGPS) correction. Raw GPS position information should not be used during the DGPS verifications. During this method, the surveyor should make sure to eliminate all the possible causes of the known sources of GPS errors to ensure the best quality of the data acquired.

Note:

During this method, the surveyor should make sure to synchronise his watch to the navigation system time and to record the time at each land observation to be used later during data reduction.

- Gyrocompass Alignment Calibration On completion of the DGPS verifications, a gyrocompass alignment calibration shall be conducted by the surveyors to determine the constant misalignment (difference) between the vessel gyro heading and the survey gyrocompass heading. The gyrocompass misalignment is variable and depending on the way and where the gyrocompass is installed. This misalignment is different from the fixed gyro error which it has to be derived in workshop by calibrating the gyro against a well known baseline. The fixed gyro error (if exists), should be written on the gyro.

There are three different methods to carry out the gyrocompass misalignment calibration. Method 1: Utilise the land survey techniques, by setting up the total station over a nearby land control station, to carry out set of observations to the bow and mid-stern of the vessel to calculate the grid heading of the vessel accompanied with simultaneous data logging (1 second update) for the gyrocompass heading data. The results of both survey sessions should be reduced based on the average time of each land observation set, the mean values to be calculated and compared against each other. Once one set has been completed the vessel will be turned through 180° and the calibration will be repeated.

Note:

Prior to the commencement of calibration operations, the surveyor should ensure the gyrocompass has had sufficient time to settle, and that the unit is firmly secured to the deck. The gyro correction should be set to zero within the navigation software prior to the gyro alignment calibration, unless, the value of the fixed gyro error is not equal zero. In this case, this error should be corrected by applying the same value with opposite sign to the navigation software prior to running the misalignment calibration.

Note:

During this method, the surveyor should make sure to synchronise his watch to the navigation system time and to record the time at each land observation to be used later during data reduction.

Also, for each set, one shot to the bow and another to the mid-stern, the observations should be quick to avoid the significant vessel movements between observations. The convergence between true and grid headings should be taken into consideration during the calculation of this method.

Page: 31 CP-SPE-0566A - Survey Quality Plan - Rev 0

Diagram 5: Gyro Calibration Diagram, First Method

Diagram 6: Gyro Calibration Diagram, Second Method

Method 2: Utilising the quay side with a well known heading to be used as a baseline to calculate the gyrocompass misalignment. Offset measurements from the quay side to two different points on the side of the vessel, one point towards the stern and the other towards the bow, will be simultaneously acquired utilising measure tapes (measurements will be undertaken over a period of 30 minutes). These tape measurements will be accompanied with simultaneous data logging (1 second updates) for the gyrocompass heading data. The measurements should be corrected to be calculated to the vessel centreline and the vessel heading to be calculated. The results of both survey sessions should be reduced based on the average time of each tape measurement set, the mean values to be calculated and compared against each other. Upon completion of the calibration the vessel will be turned through 180° and once the gyro has had time to settle, the calibration will be conducted once more.

Method 3: Utilise two independent DGPS systems to calculate the vessel heading. In this method, the GPS antennas have to be installed at the vessel bow and the mid-stern to form a baseline collinear with the vessel centreline. This baseline should be as long as possible to ensure the best quality of the data acquired. These DGPS data acquisition will be accompanied with simultaneous data logging for the gyrocompass heading data. The received DGPS positioning data should be logged for a period of a minimum of 60 minutes at an update rate of 1 second. The results of the DGPS baseline logging session will be reduced and used to calculate the vessel grid heading. The heading value will be compared against the mean value of the gyro heading data. Once the logging period has been completed the vessel will be turned through 180° and the gyro will be allowed to settle prior to the calibration being repeated.

Diagram 7: Gyro Calibration Diagram, Third Method

Note:

During this method, the surveyor should make sure to synchronise his watch to the navigation system time and to record the time at each tape measurement set to be used later during data reduction. The convergence between true and grid headings should be taken into consideration during the calculation of this method.

Upon the completion of gyrocompass calibration, the algebraic sum of both the fixed error and the misalignment calibration should be entered to the navigation software. - Static USBL Calibration On completion of the gyrocompass calibration and installation of the underwater positioning system (USBL), a static USBL system calibration should be carried out to detect and rectify gross error in the installation of the USBL system transducer. The static USBL calibration to be carried out by logging the underwater positions for two transponders deployed simultaneously to a depth of one (1 m) above the seabed level. The transponders have to be deployed at the vessel bow and the mid-stern to form a baseline collinear with the vessel centreline. The USBL underwater positioning data for both transponders should be recorded for a period of at least 15 minutes. The USBL data acquisition will be accompanied with simultaneous data logging for the gyrocompass heading data. The results of the USBL logging session should be reduced and used to calculate the grid heading of the baseline between the two transponders. The calculated baseline heading value to be compared against the mean value of the gyrocompass heading data, the difference will represent the heading misalignment for the USBL system transducer.

In Field Calibrations The following calibrations / activities are to be conducted in field and prior to and during survey operations.

• Transit check. • Sound velocity measurements. • USBL calibration. • MBES calibration. • Sector Scan Sonar verification.

- Transit Fix Check To confirm that the correct geodetic parameters have been entered into the survey software a Transit Fix Check shall be conducted around an existing platform in both a clockwise and anti-clockwise direction. - Sound Velocity Measurements A velocity cast shall be conducted upon arrival on location to measure the velocity of sound waves in water. The average value from the velocity cast shall be inputted into the USBL / MBES system. Velocity casts shall be conducted once a day during survey operations.

Note:

Prior to the commencement of calibration operations, the surveyor should ensure the gyrocompass calibration result has been entered to the navigation software. The USBL corrections should be set to zero within the USBL surface unit and the navigation software prior to the USBL calibrations.

Note:

During this method, the surveyor should make sure to eliminate all the possible causes of the known sources of GPS errors to ensure the best quality of the data acquired. The convergence between true and grid headings should be taken into consideration during the calculation of this method.

- Dynamic USBL Calibration Introduction The USBL (Ultra Short Base Line) system is an underwater navigation system that measures range and bearing to a transponder which is attached to the towed SSS or SBP system. Range and bearing are derived from phase difference measurements of the return acoustic signal arriving at the orthogonal transducer elements. Real world coordinates of the transponder are to be calculated by applying the range and bearing to the known real-world coordinates of the USBL transducer. The latter coordinates are computed through the measured offsets from the Common Reference Point (CRP) of the vessel and the application of simultaneous vessel heading, pitch and roll values. The accuracy of a USBL system decreases with range so it is important to check for (and remove) all transducer misalignment and range scale errors. A small angular misalignment of the USBL transducer head can translate to a significant positional error that increases with distance. Similarly an error in the range measurement will increase with distance without the application of an appropriate range scale correction factor. To find these errors, the USBL calibration is to be conducted in two stages by manoeuvring the vessel in a predetermined pattern around a known position transponder deployed close to the seabed. Preparation for Calibration A reference transponder will be deployed on to the seabed at a suitable location within or immediately adjacent to the survey area. Ideal sea conditions for the calibration of the USBL system are calm seas and slack tide (no current). At the chosen calibration location, the vessel will be as stationary as possible prior to deployment of the transponder. The transponder should be equipped with static release for easy retrieval upon the completion of the calibration. Also, a sufficient weight and flotation buoy should be used to ensure that the transponder is vertical and does not move during the calibration. It is necessary that the following operations should have been completed prior to the calibration:

• Verification of survey DGPS system. • Application of a valid survey gyro correction. • Measurement of VoS. • Selection of calibration site in deeper water than the survey area. • Removal of previous correction values from the USBL system.

The transponder will be deployed by the survey crew from a point on the vessel free of obstructions. The tidal drift and current will be considered prior to deployment so that the transponder is launched from the most favourable side/point of the vessel. There are two methods to conduct the dynamic USBL calibration. Calibration Method 1 The USBL calibration will be performed on arrival at site. This will be achieved by conducting the following two consecutive calibration stages: First stage, offset calibration and second stage, orientation calibration. The first stage is necessary to check that the measured offsets between the USBL transducer and the vessel common reference point (CRP) are accurate in the X, Y and Z axis. The first stage, also, calculates an accurate transponder position and depth to be used for the second calibration stage. The second stage is required to calculate the transducer pitch, roll and heading installation misalignments. Correction values for pitch and roll errors are to be obtained by comparing the angular misalignments between the transducer and the true horizontal and vertical planes. The orientation error, angular difference between the bow of the transducer and the vessel’s centreline, to be also obtained. Finally, a correction for range scale is to be found by comparing the actual transponder position with observations by the USBL system.

Stage 1: Offset Calibration The calibration will be undertaken from the vessel positioned directly over the transponder recording its position on the seabed, either on fixed four headings or a variable heading where the ship rotates slowly through 360°. During this check, a minimum of one hundred fixes will be recorded. This process will be conducted in both a clockwise, and anti clockwise direction. A maximum deviation off the initial position by 20 m should be maintained. USBL calibration software will then used to remove rogue USBL data points then iteratively reduce the data spread using least squares adjustment method. The accurate transponder position and the XYZ offset will be obtained by the software.

Diagram 8: Dynamic USBL Calibration, First Method, Stage 1

The calculated offsets will be compared with the known offsets from the vessel CRP to the USBL transducer. Also, the calculated transponder position will be used during the second stage of calibration. Stage 2: Orientation, Pitch, Roll and Range Scale

Calibration The second stage is designed to detect and quantify pitch, roll, and horizontal alignment errors. The vessel will set up at four quadrants evenly distributed around the transponder. The vessel heading should remain the same for each point selected and as a general guide the transponder should be ahead, astern and a right angles to the vessels port and starboard sides during the data gathering. To achieve this, the best setup, is for the vessel to keep its head into the weather (preferred heading), and to calculate the quadrant positions from there, the horizontal range between the vessel and the transponder should be one and a half times the water depth. Fixes taken must be evenly distributed around the transponder. At least one hundred fixes will be logged per quadrant based on the sea, wind and current conditions.

Diagram 9: Dynamic USBL Calibration, First Method, Stage 2

Using the QINSy USBL calibration module, the logged data will be processed to solve for the following parameters in one least squares adjustment:

• X and Y position of the transponder; • Pitch component (contains residual error in VRU pitch measurement plus transducer vertical

misalignment); • Roll component (contains residual error in VRU roll measurement plus transducer vertical

misalignment); • Heading component (contains residual error in the horizontal misalignment of the transducer plus

the gyro deviation); • Scale error; • Standard deviation of the transponder position.

It is anticipated that any scale errors will almost exclusively be caused by incorrect determination of the VoS in the water column. The second stage will be repeated with the vessel setting up on the reciprocal heading.

Page 145: Installation Crossing Procedure for Export Pipeline With Attachments

Page: 35 CP-SPE-0566A - Survey Quality Plan - Rev 0

The quality of the calibration will be determined by examining the following parameters:

• Percentage of processed data passed (preferably above 70%); • Derived Easting and Northing is within limits (5 m) of deployed position; • Fixed range value below 5 metres; • Standard deviation of Transducer Position (Tp) spread should be below 10 m, and the value after

corrections applied smaller than before corrections applied; • Range factor as close to 1°0 if possible.

Calibration Method 2 In this method, the vessel must be sailed around or across the transponder according to a predefined pattern to ensure balanced USBL data is obtained. To ensure that effect of time difference between surface navigation data and USBL data are kept to a minimum the vessel should be sailed slowly along its predefined course. The pattern to be sailed is centred on the position of the seabed USBL transponder. The point of closest approach of all the lines is to be approximately equivalent to the water depth. The lines start and end approximately 3 to 4 times the water depth away from the transponder. The orientation of the pattern is up to the vessel captain and survey crew to decide based on the sea and current conditions.

Diagram 10: Dynamic USBL Calibration, Second Method Calibration Verification After corrections have been applied, a verification of the calibration is to be conducted by comparing real-time observations with the actual transponder position. A navigation line of length 200 m will be sailed at an offset of 50 m on either side of the transponder while simultaneously logging data. The line will be run for a second time in the opposite direction. Data will then processed and compared with the actual transponder position to check the positional accuracy of the USBL system and was to be within the acceptable limits.

Note:

Once the transponder is on the seabed, a surface position manual fix for the deployment point should be recorded by the surveyor. The deployment water depth should be also recorded. The USBL corrections should be set to zero within the USBL surface unit and the navigation software prior to the USBL calibrations.

- MBES Calibration A MBES calibration shall be conducted prior to the commencement of survey operations. The following VoS Profile is to be carried out prior to the MBES calibration: In order to determine the Roll, Pitch and Heading corrections, QINSy survey software features a built in utility for MBES calibration patch tests. A patch test requires the following line configuration to be run:

• Latency:One line over an existing seabed feature, same direction but different survey speed. • Roll: Two lines over a flat area in opposite direction. • Pitch: Two lines over an area with slopes in opposite direction. • Yaw: Two lines over an area with slopes and lines overlapping half the swath width.

Latency Test To complete the latency test, one line will be surveyed in perpendicular to an existing seabed feature. The line will firstly be conducted at a speed of 2 knots. Then line will then be re-run at a speed of approximately 6 knots. If the vessel cannot manoeuvre /remain on line at 2 knots, run the minimum speed is to be attained. The second line must be run at 2 x first line speeds. A delay will be accurately detected up to 10 – 50 ms. Roll Test Two cross profiles will be obtained by performing two co-linear survey lines (both at standard survey speed approximately 4 knots) on reciprocal headings over a flat section of seabed close to the site, the deeper the seafloor, the more accurate the result; hence scout for the deeper are to conduct this calibration.

• If observed roll exceeds 5°, then the MBES alignment and motion sensor calibration need to be checked.

• If different roll angle were observed for a number of line-sets, the motion sensor alignment needs to be checked.

Pitch Test Two profiles will be obtained by performing two co-linear survey lines (both at standard survey speed) on reciprocal headings directly over an area with slope. If possible, a location should be chosen which has a slope over a relatively flat featureless seabed. In general the steeper the slope, the more accurate the determination of the pitch error will be.

• From the observations, if the pitch exceeds 10°, then the MBES alignment and the motion sensor calibration needs to be checked.

• If a different roll angle is observed for a number of line-sets, then the motion sensor alignment needs to be checked.

Yaw Test Two data sets will be obtained by performing two parallel, co-directional survey lines (both at standard survey speed, approximately 4 knots) with 25% overlap over an existing seabed feature.

True/Grid Headings and Convergence Calculations

Diagram 11: Convergence Calculations

- Area / Line is West of Central Meridian For line AB, the magnitude of the line grid heading (angle) is greater than the magnitude of the line true heading (angle) by the convergence angle (C), refer to Diagram 11. Gangle > Tangle Gheading = Theading – Convergence, where the convergence is –ve to the west of Central Meridian. Then, the calculation of the grid heading relative to the true heading will be as follows: Gheading = Theading + Absolute Convergence Value - Area / Line is East of Central Meridian For line AB, the magnitude of the line grid heading (angle) is lesser than the magnitude of the line true heading (angle) by the convergence angle (C), refer to Diagram 11. Gangle < Tangle Gheading = Theading – Convergence, where the convergence is +ve to the east of Central Meridian. Then, the calculation of the grid heading relative to the true heading will be as follows: Gheading = Theading - Absolute Convergence Value

APPENDIX E – PROCESSING OUTLINES

Page 149: Installation Crossing Procedure for Export Pipeline With Attachments

Page: 39 CP-SPE-0566A - Survey Quality Plan - Rev 0

Processing of Bathymetric Data During processing of bathymetric data the following checks shall be preformed:

1. Gross error check of the bathymetric data by means of comparison with water depths recorded during velocity profiles.

2. Draft measurements are correct for both frequencies in the SBES system. 3. Correct vessel offsets are applied to the corresponding sensors. 4. Data acquired by the SBES is matching in different directions and for different acquisition times. 5. Data acquired by the SBES is matching the data acquired by the MBES. 6. Data acquired on the current project matches data recorded on previous projects for the same

area. Presented below are the main steps in which the bathymetry data is processed onboard the vessel: 1. Draft and Offset verification

• Verify the MBES and SBES drafts by actual draft measurement. • Verify the MBES and SBES node location according to the vessel offset diagram. • Conduct a bar check to verify the correctness of draft, sound velocity and other settings in the

echo sounder units. 2. Sound Velocity

• Conduct regular sound velocity measurement by deploying CTD sensor twice a day during the survey.

• Enter correct sound velocity into the SBES and MBES units and provide a velocity profile cast for MBES processing.

• Verify correctness of sound velocity profile by looking at shape of MBES swath. Smiley shape will indicate possible incorrect sound velocity.

3. Tides

• Tidal predictions as per the tidal harmonic constituents for the survey area. • Verify tide by overlaying crossed line which being surveyed in different time. Also verify the

applied tides by manual applying tide into raw data. 4. Motion Sensors

• Verify the offsets and liver arms applied to motion sensor’s software. • Verify correctness of motion sensors output by looking at the values in graphic mode and

comparing existing motion sensors all together. • Verify correctness of applied heave on SBES by comparing raw and heave applied single beam

bathymetry and associated heave data. • Verify correctness of applied pitch, roll and heave on MBES data by looking at swath and

coverage of individual files and overlying on each other.

6.0 FLXMAT HANDLING PROCEDURE

6.1 PRE-EXECUTION ACTIVITES

Prior to any lift the IGO supervisor must check with the IGO Engineer that the piece is equipment is been used for the correct application. Additionally, the supervisor must check with the equipment manager that all certification is in line with Section 4.0 of this procedure. The final assembly must be in accordance to the drawing stated in Section 5.0. All cranes must be specified within their working limit.

6.2 RIGGING THE INSTALLATION FRAME

1. The selected frame is connected to crane hook via oblong link and 4 legged wire sling. Rigging

Supervisor instructs crane operator to lower and place frame directly above mattress intended for relocation.

2. Once the frame comes to rest rigging personnel assist by connecting mattress lifting rope to installation frame. One end of a flat eye webbing sling is permanently fixed to the bottom lugs of the beam. The other end is threaded through the opening of the mattress and looped into the pin and guide assembly. The lever is pushed into the closed position so that all points are contained within the pin and guide assembly.

Page 170: Installation Crossing Procedure for Export Pipeline With Attachments

Execution Plan

                                                                                                                           Page: 7 

3. All points should be doubled checked prior to giving the crane operator instructions to commence lifting the mattress. Tag lines should be place on two opposing corners to help control orientation once the mattress leaves the ground. All personnel not required for relocating the mattress should stay well clear of the task at hand. Rigging personnel are prohibited from entering directly beneath a live load under any circumstance.

6.3 DE-RIGGING THE INSTALLATION FRAME

4. When placing the mattress, the supervisor and crane operator communicate until a satisfactory

position is achieved. The mattress and frame are lowered together until all webbing slings become loose. Rigging personnel open the lever release and ensure each webbing eye is completely clear from the release beam.

5. The crane operator slowly lifts the frame. The supervisor and rigging personnel watch closely to make sure the webbing slings do not snag or catch as frame pulls away from the mattress. If snap hooks are used as opposed to the lever system care must always be taken that each link is connected and disconnected when intended.

6.4 INSTALLING MATTRESSES SUBSEA

1. Steps 1-3 of Section 6.2 shall be followed offshore when rigging installation frame on deck.

Rigging team should additionally check that safety pin is engaged prior to over boarding each mattress. The safety pin ensures that the release beams cannot become loose at any stage of the installation.

2. Frame shall have two locating beacons (one at each end) to aid placing the frame subsea. Beacons should be place well inside frame exterior in case of impact during over boarding and recovery.

3. The lever on each corner shall have a floating monkey’s fist to assist ROV/diver locating and pulling lever when the time comes. Once the installation team correctly place the mattress at the intended location the ROV/Diver is instructed to open the safety pin and release the mattress.

4. ROV/Diver must check that all webbing slings are loose with no weight acting on them before given approval to commence recovery. As the frame slowly pull away from the mattress the ROV/Diver must constantly monitor that the webbing slings are clear of all obstructions and potential snagging points.

5. The frame is recovered and placed on the next mattress for installation and the process continues.
