4 REGULATED ACTIVITIES

This report a summary of the regulated activities conducted under the licence during the year.

5 OPERATION AND MAINTENANCE ACTIVITIES

APA operates and maintains the QSN natural gas transmission pipeline and its associated facilities in accordance with AS2885.3 and other relevant standards.

All Preventative, Corrective and Reactive maintenance activities are managed within APAs Works Management System. Preventative and corrective works are scheduled and monitored for completion using this system through the generation of work orders for maintenance staff to complete.

A description of the Operations and Maintenance activities for 2014 is provided below.

5.1 Corrosion Control

5.1.1 Cathodic Protection System

The original CP system including CPUs and ground-beds on the QSN pipeline was installed in 2008. As part of the construction project for the QSNE a new integrated cathodic protection system was commissioned. It was determined the existing anode ground-beds were sufficient to provide adequate capacity to accommodate the new integrated design. The impressed current cathodic protection systems in the SA portion of the pipeline are located at Moomba and at KP 102 MLV.

5.1.2 CP Validation Survey

The most recent CP survey found that the cathodic protection system is able to provide full protection when the set points and all units are functional. The construction of the new compressor station at Moomba has required one cathodic protection unit to be switched off temporarily. Protection is provided by the other two units in the vicinity.

5.2 Pipeline Patrol Activities

In 2014 routine helicopter patrols and the scheduled annual roads patrol were completed on the QSN pipeline in accordance with the maintenance plan.

Maintenance activities including inspections of above ground pipe coating condition, fences, gates, padlocks, signage, fire extinguishers, weeding and other housekeeping activities are addressed at the meter station and pressure reduction facility associated with the pipeline.

5.3 Electrical & Instrumentation Maintenance Activities

Accuracy Verification Tests were carried out in line with APA’s maintenance management system. Meter validations and calibrations occur on a 3 monthly maintenance schedule.

Electrical compliance testing was carried out on all portable electrical equipment and residual current devices (RCD’s) at all sites.

Meter Stations Metering undertaken within Santos MGP

Connection to metering facilities at APA MPRS




Routine six monthly meter station maintenance was carried out in this reporting period. This involved calibration of all non-billing transmitters, testing all remotely operated valves, calibration of all switches and testing of all associated systems. Minor equipment failures have occurred within the reporting period with gas and moisture analysers at Moomba Inlet Station, compounding into some lost data in some cases. These issues have been resolved in early 2014.

No significant issues were reported or other significant maintenance was carried out during this period.

5.4 Mechanical Maintenance Activities

Routine mechanical maintenance activities were completed as per the maintenance schedule for the QSN pipeline system. This work involved MLV servicing, station filter inspection/replacement, vessel door closure maintenance, coalescing filter inspection/maintenance and pig launcher/receiver maintenance.

Routine inspection and maintenance activities were carried out on the pressure regulation/pressure relief systems and ESD valves at all Meter Stations on a 6 monthly basis. Maintenance tasks for the pressure control systems consisted of the inspection/overhaul of regulator seats, pilots and instrumentation filters to ensure correct operation of set points of the active/monitor and bypass regulation systems.

Pressure Safety Valves were also checked to confirm correct set point, operation and alarming functions. Where applicable, overpressure isolation valve functions are tested to ensure satisfactory operation.

All buildings and structures are inspected and maintained as part of routine maintenance procedures and confirmed in sound condition.

No significant issues were reported or other significant maintenance was carried out during this period, minor reactive faults where tended to as soon as practicable without incident.

5.5 Communications/SCADA

SCADA continued to function correctly throughout the year without incident.

5.6 Leakage Detection

APA monitors the QSN pipeline for leakage remotely from the Pipeline Control Centre and during the routine ground patrols as staff travel along the pipeline. Field staff inspect for signs of gas leakage such as dust plumes, the sound of escaping gas and dead or dying vegetation while staff at the Control Centre monitors the system pressures, flows and alarms.

During 2014, other than the reportable incident noted in section 13.1 below, there were no instances of any material leaks on valves or equipment on the QSN pipeline.

5.7 Risk Management Review

The QSN Link pipeline was constructed in 2008, and formal risk assessments, reviews and analysis were completed as part of the design, construction and commissioning process. All the action items raised in that original risk assessment were completed.

The QSNE Link pipeline was constructed and commissioned in 2011. Again, the necessary formal risk assessments, reviews and analysis were completed as part of the design, construction and commissioning process. All the action items raised in that original risk assessment were completed.

A SMS / risk assessment was conducted for the QSN Pipeline in August 2013. This assessment took place in the APA Brisbane office and was attended by the appropriate APA operational and engineering staff. The safety management study concluded that the QSN Link Pipeline meets the requirements for Safety Management Studies of AS2885.1-2012

5.8 Training

APA is committed to developing the skills of all employees and contractors to meet the operational and technical needs of its business.

During 2014 staff training was conducted in-house using a number of techniques which included training courses developed specifically for APA.



In addition to internal training, staff attended a range of external courses, conferences and seminars selected to further enhance their knowledge of the natural gas and liquid hydrocarbon pipeline transmission industry.

The range of training staff attended during 2014 included, but was not limited to;

• Clear SCADA training • APA Permit to Work • Emergency response • Drugs & alcohol policy • Isolation • 4WD training • Fire Prevention & Control • First aid • Field Induction • Excavation of Pipelines • Gas detection, Instrumentation • JHA

6 EMERGENCY RESPONSE

An emergency response exercise was conducted on pipeline licence 18 during the reporting period.

The mobilisation exercise provided practice of the procedures for handling the various implications, technical and otherwise, of a major complex event which has the potential to adversely affect the environment, public health and safety and the security of supply of natural gas and also the company’s performance, value, or reputation. In particular the exercise was conducted in order to:

• Verify the role played by the control room to ensure the safety of travelling staff; • Verify the notification and escalation processes, including mobilisation, command, and operation of

the APA Group Operations within the Queensland Transmission division; • Practise the use of all relevant procedures, guidelines, and checklist actions contained in the APA

Group Queensland Transmission emergency response plan and review their effectiveness; • Practise preparation of outgoing messages and handling of calls in an emergency, including

dealing with key stakeholders, emergency services, and relatives / next of kin of injured staff; and review their effectiveness;

• Test the adequacy of the various facilities, equipment, and infrastructure required to respond, including the support which may be required from emergency services and other parts of the organisation.

• Practice the activation of an Emergency Room and review its effectiveness.

The exercise was specifically designed not only to test these objectives but also to provide a constructive learning environment for all participants and was not conducted to test or highlight individual performance.

The exercise took place on 14 May 2014 on site at MLV102 – Moomba, South Australia and the emergency management team was based at the Spring Hill emergency response room, Queensland.

The findings of the exercise confirmed the adequacy of emergency response procedures and included positive observations and opportunities for improvement. In general, the emergency response process was executed fluently, with personnel involved understanding their role in the exercise.

7 PIPELINE CONSTRUCTION

Construction and commissioning of the Moomba compressor station, the expansion of Moomba Pressure Reduction Station and the Moomba Interconnect Pipeline was completed during the reporting period. The Station became operational in September 2014. This modification converted the QSN/E pipelines to allow bi-directional flow. Gas can now be transported from Queensland and supplied to the MSP and MAP (Western Haul), or transported from the Santos MGP into Queensland (Eastern Haul).



The compressor station also utilises a portion of the 660mm Moomba bypass pipeline (PL7) to feed gas from Moomba through to the compressor station. Following completion of the compressor station, works commenced in 2014 to install additional pipework and re-configure the station to facilitate the backhauling of gas from the Moomba Sydney Pipeline. This is known as the Moomba Compressor Station Variation 1 (V1) Scope.

7.1 Licence Variation

The Pipeline Licence was varied in respect of the above.

8 HEALTH SAFETY AND ENVIRONMENT

APA Group recorded no LTI, MTI or environmental incidents on the pipeline in South Australia during the reporting period.

APA has implemented a HSE Management System called Safeguard to comply with the national work health and safety requirements.

Safeguard provides a framework by which the processes relating to the company's Health, Safety and Environment (HSE) activities are written, approved, issued, communicated, implemented and controlled.

Safeguard applies to all HSE-related matters arising out of all activities and operations controlled by APA and its related companies (together the company) and the impact of those activities and operations on employees, contractors, the environment and the communities in which the company operates.

Additionally, Safeguard (Including HSE Policies) is also subject to review and improvement to ensure objectives and obligations are continually satisfied, including:

• Performance, measurement and reporting; • Management review; and • Audit and self-assessment.

The above requirements are supported by APA Group procedures. The HSE policy is a controlled document subject to three yearly reviews as a minimum.

9 LAND MANAGEMENT

9.1 Land Owner Liaison & Public Safety Awareness

The landowner liaison program includes a landowner package being sent to landowners and direct liaison as required.

Council and Emergency services are contacted and, where possible, gas awareness presentations delivered as per APA Stakeholder Management program.

9.2 Pipeline Location and Referral services

APA provides a free “dial before you dig” service which third parties can call to locate any pipeline infrastructure prior to undertaking any construction activities. The service is primarily used by other companies and third parties carrying out civil works in the vicinity of the pipelines and other buried utilities.

10 ENVIRONMENTAL MANAGEMENT

There were no environmental incidents during the report period.

An assessment of compliance against the SEO objectives in regards general maintenance activities is included in Appendix 1.

During the reporting period all environmental requirements as detailed in the Statement of Environmental Objectives were complied with.



10.1 Monitoring

Ongoing environmental monitoring of PL18 is intended to ensure effective rehabilitation has occurred along the pipeline route. The most recent monitoring included ground patrols and a helicopter flyover of the pipeline route to assess vegetation regrowth, erosion and subsidence and to confirm the effectiveness of previous subsidence repair work.

Overall it was determined that the QSN pipeline route was generally in good condition. Minor subsidence at Strezlecki Creek, KP120, will continue to be monitored and managed.

Right of Way maintenance, including minor subsidence and erosion identified between KP0 and KP160, is scheduled to occur between April and June 2015.

10.2 Projects

A CEMP was submitted setting out the environmental management practices and procedures to be implemented during construction of additional pipework at the Moomba Compressor Station to meet the environmental requirements of the Project. These requirements are documented in:

• the QSN Pipeline Statement of Environmental Objectives (SEO); and • the Moomba Compression Services Variation 1 (MCS V1) Project Construction Environmental

Management Plan.

11 MANAGEMENT SYSTEM AUDITS

APAs auditing program offers the opportunity to identify and promote continual improvement within APA.

11.1 Management System Audits

An independent audit of the APA Pipeline management System by external auditors Ken Cameron & Associates is scheduled to occur during June 2015.

APA completed a number of management system audits during the year under its internal audit program.

11.2 Health and Safety Audits

An internal audit schedule of the Safety Management System was maintained during 2014.

12 COMPLIANCE

APA ensures that the pipeline is operated in accordance with the relevant Acts of Parliament, licence conditions and the requirements of AS2885.

APA attends quarterly compliance meetings with DSD, where operational regulatory compliance is discussed in an open manner.

Changes in legislation are tracked and communicated through a The Technical regulatory Manager.

APA maintains a compliance database, MARCIS, which tracks legislative compliance throughout the organisation. Obligations are assigned to responsible staff, who must supply evidence that the obligation has been satisfied within a specified time period.

APA is not aware of any regulatory non-compliance for this pipeline, and believes it is fulfilling its obligations in relation to the following requirements:

• The Petroleum & Geothermal Energy Act 2000 • The Petroleum & Geothermal Energy & Regulations 2013 • Pipeline Licence (PL18) • The Statement of Environmental Objectives

APA Group maintains an action tracking system for improvements to its systems, which is fully traceable through to close out of individual items.

Significant items are reported through to DSD, and would be raised at the quarterly compliance meetings held between DSD and APA.



There have not been any significant regulatory compliance issues during this reporting period.

13 REPORTS

The following reports were generated and forwarded to DMITRE during the reporting period;

• PL18 2014 Annual report • MCS V1 Activity Notification • MCS V1 Design Basis Manual • MCS V1 Project AS2885 1 Design Compliance Register • MCS V1 CEMP • MCS V1 SIL Closeout report • MCS V1 HAZOP Closeout Report • MCS V1 SMS Closeout report • MCS V1 PL18 Licence Variation Application

13.1 Incident Reports

During the reporting period there were no “Serious Incidents” and one “Reportable Incident”. The reportable incident was reported later than required under Petroleum and Geothermal Energy Regulations 2013 s32(5). An overview of the reportable incident is provided below.

13.1.1 Incident date

The incident occurred on 23rd October 2014.

13.1.2 Incident Location

The incident occurred at the MLV102 site located at KP 102 on the QSN pipeline, near Innamincka SA.

13.1.3 DSD Incident Classification

Design

13.1.4 Incident Description

The threaded cavity vent connector on a ball valve failed during operation of the ball valve, causing the cavity vent assembly to detach from the ball valve and leading to a localised release of gas. A second vent connector was also observed to have failed at a previous time.

13.1.5 Root Cause

The root cause of the failures was assessed as vibration-induced fatigue of the threaded connectors. The design of the cavity vent assembly was such that the connectors were subjected to bending loads and vibration from the adjacent pressure control valve.

13.1.6 Corrective Actions

• The site was initially made safe and the affected valves isolated and tagged out of service. • An engineering and metallurgical investigation was completed to assess the root cause. • Replacement cavity vent assemblies were sourced and installed using a modified design. • Overhaul and vibration assessment of the pressure control valve has commenced.

A review of similar sites has commenced to identify other valves that may be at risk of similar failure (cantilevered connector design and subject to vibration).

13.1.7 Status

In progress.

14 THREAT PREVENTION AND MITIGATION

There are no reasonably foreseeable threats on this pipeline.



14.1 Overview of Risk Management

APA Group recognises that risk management is an integral part of good management and that managing risk is a fundamental part of its business so that actions and activities do not unduly expose the asset, its personnel or the public or the environment to unacceptable risks.

The risk management process consists of well-defined steps which, taken in sequence, support better decision-making by contributing to a greater insight into risks and their impacts. The risk management process can be applied at many levels within APA Group and can be applied to specific projects, to assist with specific decisions or to manage specific recognised risk areas. APA Group recognises that risk management is a multi-faceted process, which is often best carried out by a multi-disciplinary team with an intimate knowledge of the pipeline.

APA Group’s risk management processes aligns with the Pipeline Integrity Management requirements as defined by AS2885.3 and comprises the following components:

• Technical risk management as per AS 2885; • Facilities HAZOPs/Internal Hazard Audits; • Risk management, including Health, Safety and Environmental (HSE) risk, as per APA Group’s

corporate policies; • Environmental Management Plan as per Australian Pipeline Industry Association (APIA) Code of

Environmental Practice and Queensland Environmental Acts; and • MAOP reviews as per AS 2885;

All facilities and equipment are currently being operated and maintained to AS 2885.3, Original Equipment Manufacturers (OEM) operation and maintenance recommendations and good industry practice.

14.2 Risk Management

The company has exposure to a wide variety of risks. The following are some of the most relevant:

• Frequent vehicle travel incident - Major (LTI or Vehicle write-off) • Lifting loads near the exposed pipeline • Hot work • Moveable plant in hazardous areas • Use of and maintenance of gas transportation facilities, other than high-pressure gas pipeline

lines • Isolating pipe work • Storms/lightning • Equipment theft and damage • Low operational availability (reduced availability of competent, skilled qualified personnel due to

sickness) • Corrosion and Stress Corrosion Cracking • CAD welding • Floods • Seismic events • Aviation travel • Third party excavation activities near buried pipelines • Electrical hazards on pipelines due to lightning or overhead powerlines

14.3 Specific Asset Risks

Risks of higher significance include:

• For remote pipelines, exposure to prolonged long-distance driving. This risk is mitigated by driver training courses coupled with stringent remote travel requirements including remote monitoring by the Control Centre.

Asset risks are mitigated and monitored via APA work programs and systems including but not limited to:

• Aerial Patrols • Landowner and Third Party Liaison • SCADA monitoring • Maintenance programs • Safeguard implementation



15 FUTURE WORK PROGRAM

All maintenance operations will continue to be completed as scheduled to ensure that the integrity of the pipeline system is being maintained, as well as the safety and efficiency of APA Group’s operations.

The following specific activities are planned for FY15:

• The modification of the Moomba Compressor Station by the installation of additional pipework and re-configuration of the station.

16 EXPENDITURE STATEMENT

17 PIPELINE OPERATION

12,077.69 TJ of natural gas was transported through the QSN pipeline during the 2014 period.

18 CONCLUSION

The maintenance and inspection programs carried out on the QSN Pipeline in 2014 have indicated the pipeline is in sound condition and is capable of operating at set parameters with no restrictions.

The CP Survey results indicate the protection levels are adequate to provide suitable protection for the pipeline.

The pipeline is considered to be in good working condition and well maintained.
