Welcome to the SPE Topsides UK 2017 Conference and Exhibition.

SPE Aberdeen is delighted to be working with Mearns & Gill to deliver Topsides UK 2017, a platform for the industry to engage on the key areas affecting topside operations.

With the focus still very much on maximising the economic recovery of the UKCS’ oil and gas, we have brought together top subject matter experts from across the industry to share their knowledge, lessons learned and innovative services and solutions, ensuring that we continue to work efficiently, and together.

This year’s conference has attracted the most interest to date and will see a mixture of operators and service companies delivering presentations on areas including ‘Improving Production Efficiencies’, ‘Maintaining and Improving Integrity’, and ‘Appropriate Topsides Technology’. It is with the support of all areas of the industry that we can continue to provide delegates with valuable content from a range of perspectives and ensure we provide a high quality training and development opportunity for everyone.

We are grateful for the support of such a hardworking and enthusiastic technical committee as without them, the conference would not have been possible.

Like many not-for-profit conferences, Topsides UK depends on the support of the industry and I would like to thank all of our sponsors. Any surplus funds raised will be reinvested to support important initiatives which continue to inspire our future generation of young engineers.

I’d like to thank our exhibitors and please do take the opportunity to speak to them during the networking breaks and the networking reception on Day 1.

Day 1

Abstracts : Day 1 09.10 Morecambe Hub DP6/8 Maintenance & Simplification Campaign | James Barlow, Centrica

The South Morecambe gas field with GIIP of 5.5 tcf produced first gas in 1985. The field is produced through a three-jacket central compression complex and four remote normally unmanned platforms.

As is common with many older NUIs, in late life, access limitations imposed by a fly to work operating model make liquidation of work packages difficult. The consequences are an increased work backlog and integrity anomaly list.

In 2017 Centrica will launch an integrated maintenance and simplification campaign as part of a wider hub simplification strategy suited to late field life operations with the following objectives:

– Resolve outstanding integrity anomalies and fabric maintenance issues

– Simplification of existing systems.

Removal of redundant equipment, simplification of the process flow route & upgrades to instrumentation/control systems will reduce the inspection & maintenance demands of these installations, leading to the following benefits:

– Removal of unnecessary topside equipment- preventing a reoccurrence of growth in maintenance backlogs

– Increased safety of operation due to fewer visits to the platform

– Reduction in overall facility risk

– Lower operating costs

– Optimisation of production flow path

– Increased field life.

09.30 Integrity Under a Microscope | Fraser Selfridge, TAQA

A drive to improve our Process Safety Performance across our organisation under the mantra of ‘Safe Business is Good Business’ has changed TAQA’s culture and altered the response taken to identified integrity issues. This has increased deferment of production to address integrity defects and subsequently the focus of the business to improve integrity performance.The presentation will look at the re-active and pro-active driven changes to how TAQA manage integrity using the following examples:

– Near Miss – Low wall thickness identified from planned inspection of a dead leg

– External Audit – Improvements in the Risk Based Inspection process

– Industry learnings – Corrosion Under Insulation

– Offshore HSE Finding - Failure to manage a known defect appropriately.

The impact of the changes to TAQA’s Integrity Management systems will also be reviewed and discussed.

10.30 Wireless Sensor Monitoring of Cathodic Protection Solutions | Andrew Connelly, Proserv

With an ageing field of assets in the North Sea and beyond, and a recent rise in decommissioning, extending the life of active and profitable assets is necessary to maximise revenue.

Asset life extension is achieved by cathodic protection systems, and therefore it is necessary to monitor the effectiveness of this protection to ensure extended life of the asset and avoid premature decommissioning. Traditionally, monitoring has been completed through periodic ROV survey. This is a relatively expensive method to achieve infrequent measurements that are difficult to repeat accurately.

With permanently deployed sensors and wireless communications, it is possible to quickly recover measurements from across the whole platform structure. Repeatable measurements allow the highest accuracy to be realised, so that decisions on the level of protection required can be made based on good data. Reliable wireless communication using acoustic signalling is now a reality, proven on high integrity requirements such as BOP control systems.

Acoustic communication has now been successfully applied to the environment between and around platform jackets, where obscured signals and high multipath conditions have previously challenged traditional acoustic communication. As a pioneering project, this has now been rolled out on a North Sea platform.

This paper will present the challenges of this development as a case study, and the success that can be achieved from taking an innovative approach.

10.50 Long-Term Integrity of Engineered Composite Repairs | David Johnson, Health & Safety Executive

Engineered composite repairs are increasingly employed in offshore oil and gas applications where they are used to repair a range of components and structures. The uptake of this repair technology has increased dramatically over the last decade, with end users capitalising on a range of benefits, particularly the repair of complex geometries.

Originally, such repairs were viewed as a short-term temporary solution to allow production to continue uninterrupted until a more permanent repair or replacement option could be implemented during planned maintenance. However, in recent years, consideration has been given to the use of such repairs for extended periods. Whilst in general the performance of engineered composite repairs has proven to be satisfactory, there continues to be uncertainty relating to their long-term integrity and performance. Given this uncertainty, HSE has recently initiated a shared research project, supported by industry, to improve our collective knowledge in this important area.

This paper will provide a general overview of the technology, applications, operational experience to date and an overview of the shared research project.

11.10 Hydrocarbon Containment: Translating Data into Action | Doug MacLeod & Mike Skidmore, Maersk Oil

Maersk Oil has targeted and achieved a substantial reduction in hydrocarbon releases in the last two years.

The team leading the work took a step back and realised that effectively capturing and analysing the data from smaller leaks and seeps ultimately was the answer to targeting hydrocarbon releases on a larger scale. They developed a revised valve management philosophy, revisited the way they maintained small bore tubing and worked to understand and manage the impact of vibration. This was achieved through collaboration between assets, functions and the supply chain.

Operating a late life asset brings its challenges but regardless, every operator should be aiming for zero releases. Like many in the industry, we’re still on this journey but we’re making progress. We’ve found it to be extremely important to make sure that everyone in the business, no matter their position, understands the role they play in preventing hydrocarbon releases and keeping colleagues safe. Analysis and regular communication of the data has been key in promoting that understanding.

Representatives from Maersk Oil would like to talk you through the details of our ongoing journey and share our story so far.

11.30 FRACAS (Failure Reporting, Risk Analysis & Corrective Action System) - a New Dimension to Reliability | Pol Stewart, Enkelt

The FRACAS process (Failure Reporting, Risk Analysis & Corrective Action System) allows asset management to proactively manage all vulnerable areas (incl. production loss, equipment failures, obsolescence, degradation of integrity, etc.) within a single recognised reliability process consistently throughout the life of an asset. The process can, for example, assist operators to improve production and reduce costs by;

– Identifying vulnerable areas through events that threaten production assurance (e.g. the unexpected degradation of a control valve or deterioration in performance of a pump).

– Evaluating the risk of these events recurring or escalation into a more serious threat

– Allowing for prioritisation, cost/benefit analysis of mitigating activities and alignment of business objectives in a proactive, disciplined, pragmatic manner

This process was successfully deployed on board an FPSO in the UKCS, enabling a fresh approach to identify the real & immediate needs of the asset, enabling asset management to direct focus and align priorities amongst all stakeholders with significant success, improvements through the introduction of this process included;

– Increased availability & uptime with avg uptime of 98% @ 28,000 bopd (Q3&4 2015)

– Maintenance backlog reduction of 25,000 hrs

– Compliance with all planned maintenance KPIs (first time since being introduced).

13.05 Maintaining and Improving Integrity of Corrosion Monitoring Fittings on Ageing Assets | Alan Taylor, ICR

As offshore assets mature and age, corrosion monitoring access fittings on associated process systems pipework can become corroded with the integrity of the fitting, over time, being compromised. As a result, the fitting cannot be used to obtain valuable corrosion data or, worse case, can become a potential leak path if not maintained.

Using a collaborative approach across company divisions, we have developed an innovative solution for cap removal which is both efficient and safe allowing many caps to be removed in a short space of time. We have developed intuitive machining equipment to quickly remove seized covers and carrier plugs from access fittings. The access fitting sealing face and threads can also be machined and refurbished to allow the fitting to be brought back to an “as new” condition. The access fitting can then be serviced safely during future online work scopes, ensuring the operator has accurate corrosion monitoring data which can be vital for high risk pipework and systems. This new method allows for fast turnaround in comparison to lead times associated when ordering/installing new spools/access fittings.

By using multi-skilled engineering teams, we have improved productivity offshore therefore reducing the number of vendors and visits resulting in direct cost savings for our clients.

13.25 A Structured Approach to Offshore Crane Maintenance | Michael Laird, EnerMech

Offshore cranes are vital pieces of equipment and are often classed as “safety critical” in the Duty Holders Safety Case.

When things go wrong this can range from component failure potentially resulting in large consequential costs, right up to catastrophic failure with potentially dire results.

This paper looks at the evolution of offshore cranes predominately used in the North Sea and a history of some of the failures and the lessons learned from them. It outlines the various approaches to maintenance available to the owner. Traditionally these have been time based, using information given by the OEM, but as the industry gained more experience this evolved into risk based regimes using techniques such as FMECA (Failure Modes and Criticality Analysis). Now, by using more sophisticated tools, we are moving into condition based systems of maintenance with the aim of producing a fit-for-purpose maintenance approach at the optimal cost. The importance of an effective auditing system to check the cranes’ condition is touched upon which provides an important feedback loop to gauge the effectiveness of the maintenance.

13.45 Non-Invasive Inspection (NII) of Pressure Vessels | Andy Morrison, ConocoPhillips

The invasive inspection of pressure vessels is hazardous to personnel, costly to carry out and is frequently the critical path during turnarounds. By utilizing NII correctly, it is estimated that the UKCS could save $500m per annum from increased production and reduced enabling service costs.

The HOIS Joint Industry Project DNV Recommended Practice (RP) G103, provides guidance on the use of NII as the primary means of establishing the internal condition of pressure vessels. By applying this, RP operators can achieve these savings and carry out a more effective inspection of their pressure vessels.

ConocoPhillips has implemented this RP on our UK assets for over 10 years and realized significant benefit. This presentation will provide a key insight into:

– Case study on applying NII and the benefits achieved

– Discuss the effectiveness of IVI vs NII inspection

– Compare the difference in cost, and how it is made up, between IVI and NII

– The benefits and risks for NDT service companies offering “NII service”.

The presentation will also cover the increasing use of other forms of ‘NII’ ConocoPhillips deploys e.g. Unmanned Ariel Vehicles (UAV), and the need for appropriate guidance to manage their use.

14.55 Maintaining & Improving Integrity in a Low Cost Oil Environment | Rebecca Allison, Oil and Gas Technology Centre

The challenge of managing assets reaching or operating beyond their design life has been prevalent within the offshore industry for some time and continues to grow. The management of mature assets is a global issue with a number of mature basins throughout the world.

How effectively we, as an industry, deal with that challenge will impact on the overall longevity of the industry.

This presentation looks at this issue from an Asset Integrity Management perspective, considering three specific but related aspects. Firstly, the management of the asset portfolio and the main asset integrity issues arising from late life operations in a high operating cost environment, compounded by low oil prices. Secondly, the specific practical issues relating to asset integrity such as on-line condition monitoring, corrosion risk assessments and shutdown management. Thirdly, examination of how an effective management system approach contributes to the management of mature assets including culture and human factors.

The presentation will then focus on the key issues relating to integrity inspection techniques, including how to retain the safety and operability of the asset by optimising inspection whilst retaining integrity and the technologies emerging from the oil and gas industry and beyond to optimise this process.

The key focus areas of the presentation are:

– Data management, Risk profiling, Obsolescence management, Operating Models, Application of technology.

15.15 Safety Enhancements and OPEX Savings from Appropriate Installation of Flexible Deluge Pipework | Alan Sherriff, TAQA

Persistent failures during deluge testing prompted TAQA to scrutinise the market place for suitable cost effective methods of integrity delivery. The chosen solution (flexible deluge pipework) has delivered improved testing performance, whilst reducing maintenance costs and assuring on-demand deluge performance.

The presentation will cover: • An explanation of the problem with increasing wet test frequencies and the cost of response to these failures

– The impact of the previous testing regime on the installation

– High level identification of considered options and potential for success

– Cost review of chosen option over previous regime

– Design considerations overcome during replacement programme

– Delivery of success

15.35 Heavy Reduction of CAPEX on Offshore Production Platforms/Vessels by Use of Digitilatization Solutions | Edmund Knutsen, Siemens

The optimizing and reduction of costs for maintaining your assets is a goal in most plants. Moving from calendar-based maintenance to Condition-based maintenance (CBM) is a methodology that enables you to identify and predict pending equipment failures.

Especially on offshore vessels/platforms, the savings are huge by moving to CBM and running the maintenance in well planned campaigns. A use case from an offshore oil & gas producing platform will be presented to show how performing analyses on logged data and presenting the results to the stakeholders - the maintenance planners and the operational managers. To obtain these functions Siemens has developed a set of effective analytics and excellent visualization techniques.

A live demonstration of the capabilities on the Ivar Aasen platform can be shown during the presentation.

15.55 Digitization or Smart Use of Readily Available Operational Data | Esther Lian, NOV

Sea Water treatment systems have standardized on membrane technology in recent years to supply the necessary injection water for profitable oil production. These systems utilize control logic to automate the day to day operation. Because of this control logic, the systems are often considered “black boxes” to operators.

With even the most robust control logic, the systems can be fragile and susceptible to external influences of sea water composition. Fluctuating levels of total suspended solids (TSS),

bacteria and algal population density can have significant impact on normal operation. These nano-pore membranes are susceptible to fouling and can be very difficult to restore to normal operation thereafter. Availability of the membrane systems is crucial for assurance of oil production.

Total assurance of membrane system availability is achieved through proper monitoring of the overall system through expert knowledge and experience. Bringing efficient visibility to the readily available process data of the membrane systems will result in predictive controls to prevent costly upsets in their delicate operation. Smart data handling and interpretation via software will be the way forward for a predictable and optimised operation.

16.15 Tracerco Process Diagnostic Solutions to Oil and Gas Separation Issues | Andrew Shaw, Johnson Matthey

As the Oil & Gas industry transitions into what is perceived as the “new normal”, Operators face greater challenges to optimise process facilities and maximise production while keeping operating costs as low as possible.

Tracerco offers unique online and non-intrusive measurement and diagnostic technologies to assist operators with modification and optimisation projects, enabling maximised production efficiency with minimum cost impact.

In this paper the use of radioisotope technology for accurate online process studies and inspections will be introduced, and examples of how the technology has been utilised as a troubleshooting tool will be discussed. In particular, examples of how the technology was used to verify process models, optimise production by online inspection of production critical equipment, and minimise and/or prepare for planned shutdowns will be presented.

Reduction in Time Taken to Decontaminate Process Plant for Manned Entry | Peter Reynolds, Denholm MacNamee

Denholm MacNamee is a long established company providing support services for the Oil & Gas industry, particularly innovative asset cleaning and decontamination solutions in both onshore and offshore environments.

Denholm utilise a unique decontamination process which removes H2S, LEL and benzene whilst de-oiling and conditioning residual solids thus facilitating their removal and disposal. The product used is aqueous, and low hazard to personnel and environment. The chemical product, ZymeFlow® is CEFAS and REACH registered.

The chemical is applied in a Vapour Phase® or a boil out process, which are completed in a maximum of 12 hours processing. Effluent volumes from the process are minimised and is a neutral pH, aqueous solution with COD of 2000ppm which is acceptable for discharge directly to site WWTP with no additional processing. Processing steam is MP wet steam which can be taken from site supply or via a temporary Zone II rated boiler if required.

Denholm use experienced multi discipline technicians to implement the process and we show an enviable record in terms of both project performance and in HSE considerations.

Denholm have applied this technology for the past fifteen years and can show many endorsements and case histories in evidence of this superior and cost effective method of process plant decontamination.

Non-Intrusive Inspection (NII) of Topside Assets with Advanced MEC Technology | Andreas Boenisch, Innospection

This presentation focuses on the use of the next generation MEC (Magnetic Eddy Current) technique, which is a further development of the fast corrosion screening SLOFEC technique, for the inspection and integrity support of pipelines, pressure vessels and drums.

The MEC technique operates on a high frequency Eddy Current field with a controlled direct current magnetic field and specially developed sensors to achieve a high sensitivity in defect detection in the ferromagnetic and non-ferromagnetic materials including through the typical coatings like Monel.

Internal and external defects such as individual pitting, microbiological corrosion, carbon dioxide corrosion, etc. are easily detected by the MEC technique while the differentiation between the different defect position and other occurrences like laminations or inclusions are also shown. Applied during process conditions, the MEC technique is ideally a Non-intrusive Inspection (NII) technology. Case studies and field experiences of the MEC technique for pipeline and pressure vessel inspection will be presented.

The next generation Pulsed Eddy Current Testing (PECT) technique for corrosion under insulation (CUI) inspection will also be presented. The PECT technique offers increased defection detection capability and operational speed and is capable of inspecting through 250mm coating thickness for the defects hidden under the insulation.

A Novel Approach to Gas Metering During Well Testing, Utilising a Variable Differential Pressure Cone Meter | Gavin Munro, GM Flow Measurement Services Ltd

Well testers have often voiced concerns about the hazards and inefficiencies of using Dual Chamber Orifice Fittings, so a complete re-design approach was needed. A new device offers a unique gas flow meter, with relatively large turndown ratio, simple range change, no gas release during operation and the ability to minimise personnel intervention.

A moving internal sliding sleeve is used to change the dimensions of the flow element, allowing the range to be matched to the flowing conditions. Each range change is achieved by activating an air driven motor, which moves the sleeve into the high or low range, with no break in the pressure envelope, nor hazardous gas releases. The operation takes 30 seconds and can be carried out manually or automatically by an integral flow computer. The flow computer can be used to remotely change the range in case of a sudden or gradual increase or decrease in the flow rate over time.

There is no need for personnel to “suit-up” in high H2S environments, since no gas release means the operators are not exposed to neither hydrocarbons, nor H2S.

Differential pressure cone meter technology is inherently more rugged than traditional thin orifice plates which can buckle, wear, or can be installed backwards. The new ISO-5167 part 5 differential pressure cone standard recommends only 6D and 3D upstream and downstream straight lengths. When compared to 19D to 43D for orifice meter runs, this vastly reduces the footprint of the installation.

The completely machined design, has no pressure retaining welds, nor NPT threads to fail. Erosion, corrosion, fatigue and maintainability have all been addressed at the design level to maximise uptime. Double pressure seals, each with dual elements, eliminate the possibility of leakage.

We will show how we have produced a small but important piece, in the overall efficiency drive, which is needed to maximise the life of infrastructure and reduce the costs of oil and gas extraction.

What Lies Beneath? The role of technology in addressing corrosion under insulation | Scott Westwater, Bilfinger Salamis UK

Corrosion Under Insulation (CUI) is perhaps one of the most significant integrity threats that the oil and gas industry faces today. Water ingress causes damage to pipework and other susceptible steel elements, but the corrosion process underneath existing insulation materials is one of the most difficult to prevent.

A common inspection technique used for CUI is to simply remove the insulation and perform a visual inspection initially.

The removal and reinstatement of insulation is labour intensive, expensive and in many instances completely unnecessary, as the substrate can often be found to be in good condition.

At Bilfinger, innovative technologies are combined with multi-disciplined rapid close visual inspection (RCVI) teams that consist of multi-disciplined rope access personnel to quickly deploy a range of CUI management processes.

Abstracts : Day 208.30 Herding Cats and Burning Ferraris – an Operator Insight into Achieving and Maintaining a Sustainable Business in a Low Cost Oil Environment | Ross McHardy, TAQA

Aligning a team or an organisation in the pursuit of common, agreed goals is difficult because it involves people and people are complex. The last year or two in the Oil Industry with the challenging oil price has both forced and enabled us to roll our sleeves up and deal with multiple issues that we should have been on top of before. I will talk about where we started, what we have done and how we need to not only sustain it, but take it a stage further.

I will talk about the low oil price and the resulting unsustainable businesses as an enabler to rectify some really poor practices. I will give some examples of poor performance and touch on some examples of recent changes that should have been no brainers – industry wide.

I will give an overview how we have dealt with it in TAQA with some examples of the results to date.

I will discuss functional or asset based structures and the key to making either work and discuss offshore models and the importance of simplicity, clarity and empowerment.

I will try to tie together Culture and Behaviours and the resulting improvements in efficiency, safety and integrity.

I will give my view on where we are now and what we and the supply chain need to do next to ensure that we can maintain sustainable businesses and ensure that we have an industry to be proud of and a way to pay our mortgages for years to come.

8.55 Worst to First—How One Leader’s Focus on Culture Enabled a Remarkable Organization Turnaround | Isabel Fernandez, Wilson Perumal

When U.S. Navy Commander Ernie Spence took over the Navy’s largest squadron, it was the worst performing squadron in the Navy. For this FA-18 squadron, the challenges were great. The squadron was averaging 4.5 significant safety incidents per month, was 20% over maintenance budget, training requirements were over a year behind schedule, and most astonishingly, only 1 of the squadron’s 117 aircraft was deemed “safe to fly.”

With an intense focus on improving the organizational culture of the squadron, Ernie was able to turn the squadron around in less than 18 months. He was able to reduce safety incidents to less than 1 per quarter, increase flight hours flown by 44%, restore the squadron’s training program, and was recognized as having the best squadron maintenance program in U.S. Naval Aviation, all while coming in 21% under budget. Specific topics to be explored during this presentation:

– The characteristics of organizational cultures that lead to Operational Excellence & High-Reliability Performance

– How to identify the cultural gaps that affect your organization’s safety, quality, reliability, and profitability

– Actions you can take to drive positive cultural transformation in your organization.

09.20 Treat Reliability Like Safety | Mike Wilkinson, ConocoPhillips

Robust Safety and Plant Reliability performance are driven by the same fundamental principles of Loss Prevention. The building blocks of the respective Safety Management and Reliability Management Systems that drive the culture and performance are the same – for example each needs Management Policy & commitment, Robust controlling procedures, clearly defined organisational structures, roles and responsibilities, effective Hazard/Threat identification, quality loss investigation, management assurance etc.

By comparing and contrasting what is in place to manage both Safety and Reliability for each of these building blocks, ConocoPhillips has started to identify opportunities to align best practices and raise plant reliability performance. In addition, there is the opportunity to feedback improvements to safety management. For example, comparing the roles and responsibilities of the onshore Safety Advisors with Reliability Engineers resulted in moving the engineers from sitting in a functional department to being embedded in the asset, whilst still retaining their functional reporting lines to ensure independence from the asset.

Utilising this approach is proving effective in the identification, and communication to the organisation, of opportunities – if it is good for safety then there is a strong argument that it is also good for reliability.

10.35 Brent Charlie Ultra Late Life: A Journey in Optimising for Platform Decommissioning | Ian Jackson, Shell U.K Ltd

Are there still prospects in a 40 year-old platform undergoing decommissioning? Is it still possible to maintain a net production gain during abandonment? What kinds of operational activities are possible to achieve this? What opportunities are there for me to develop technically and professionally as a new entry into the industry?

This presentation discusses my journey with Charlie and what we discovered as we move into Ultra Late Life. We may not be drilling new wells, but Brent Charlie is still a net exporter with 16 active producers. I realised that there is still a lot of opportunities here that can be delivered in parallel to decommissioning, including novel topside modifications for well integrity and production optimisation. Additionally, other key opportunities included WRFM, early Plug and Lubricate (P&L) of shut-in wells and reduction of platform well maintenance/testing – allowing greater focus on key value adding activities.

The success of this initiative on Brent Charlie is demonstrated by balancing the use of our team offshore between abandonment and production optimisation in order to not only remove integrity risks around long-term shut-in wells, but deliver production gains that have effectively paid for the well P&L work. This offshore experience was critical for my development as a young professional in the industry. The opportunities were there for me – I just had to look for them.

Technology Showcase 11.00 – 12.00

Improving Safety and Efficiency with Offshore Technology | Liam O’Neil, Amec Foster Wheeler

An innovative approach to data management, engineering, and design on a greenfield project is making operations safer, improving data integrity, and significantly increasing efficiency.

Included in the suite of new technologies being used on the project is the use of topsides visualisation using ATEX-rated offshore tablets and helmet cameras. This has allowed for first person walk-throughs and virtual reality visors to live trouble-shoot in tandem with those in the office.

Continuing the theme of technologies that enable collaborative, effective decision-making, traditional workpacks have been replaced with smarter digital workpacks, providing a host of benefits and efficiencies which could be adopted by the wider industry with the right infrastructure.

The successful introduction of a range of sustainable technologies has been underpinned by positive organisational culture and workforce engagement. At this talk, the presenter will provide and overview the technologies, the challenge of change, as well as the cost, schedule and safety benefits of using new technologies in an offshore environment.

Driving efficiencies by adopting mechanical Connectors as a Cold-Work Solution for Permanent Pipe Connection | Ron James, STATS Group

By far the most challenging activity for any operator is the planning and execution of maintenance activities and repairs. The safety of personnel and assets are the primary consideration for all oil and gas operators. Therefore, the execution of repair and maintenance work scopes demands the use of safe, reliable and efficient equipment. This paper will highlight the safety benefits of permanent mechanical pipe connectors to replace welding of topside piping or pipelines, eliminating the associated risks with hot-work.

This DNV GL Type Approved cold-work solution significantly reduces maintenance costs and duration by eliminating the need for welding equipment, personnel, habitat and specialist skills. When comparing typical costs associated with welding a 4” weld neck flange, operators save on average £30,000 when chosen to installing a mechanical connector. The slipover design and external gripping assembly enables quick and efficient installation, with only basic pipework preparation, resulting in timely completion of maintenance activities. The external grip assembly applies even linear and circumferential load around the host pipe, eliminating localised material deformity or stress fractures which prevents flow restrictions or turbulence.

Mechanical connectors have been fitted to a variety of piping systems with a 100% leak-free service history. Ranging in size from 2” to 36”, and for pressures up to 51 bar as standard, mechanical connectors provide cost-effective piping repair, tie-in or capping of redundant pipe work.

Further efficiencies can be achieved when operators share costs and become part of an emergency pipeline repair system (EPRS) club. Operators who are part of an EPRS club can mitigate against the consequences of unplanned maintenance and reduce response time by having access to connectors maintained in a state of readiness in accordance with client specifications.

Bulk Water Removal System - Produced Water Debottlenecking to Unlock Production | Chris Bennie, Expro

With rising water production and an oil price crashing to levels not seen since the mid 90’s, maintaining the profitability of mature assets through 2017 is key.

Bulk Water Removal Systems can revolutionise the economics of mature field developments with very short project paybacks. These simple systems can help operators unlock lost production by (i) allowing the production of previously shut in, high water cut wells, (ii) lowering the back pressure on producing wells and (iii) ensuring new wells can be produced through the existing downstream facilities without modification.

Bulk Water Removal Systems are compact systems which utilizes cyclone technology. In a two-step approach. These systems represent low cost alternative to large residence time systems which can be used to extend the operating envelope of existing processing facilities. These systems are skid mounted and can be rapidly deployed to unlock production.

The results from recent field trials carried out offshore in South East Asia will be presented, together with the performance of a full scale package also installed in South East Asia.

Choosing a right solids management strategy and technology can increase production while reducing cost per barrel. A deliberate sand removal strategy contributes majorly to enhancing production performance of underperforming wells.

“Access” All Areas | Brian Bendel, AquaTerra

It’s no secret that more than half of the fixed platforms in the UKCS have already exceeded their 25 year life span – the ageing process bringing an inherent increase in risk attached to the maintenance of infrastructure. Rope Access continues to play an important role in solving maintenance issues in the offshore Oil & Gas industry, providing a safe, efficient and non-disruptive solution.

Having safely and proficiently completed a diverse portfolio of more than 1000 multi-disciplined projects using rope access techniques, AquaTerra decided it was time to look at alternatives, striving to exceed the safety performance and efficiency of rope access, and as a means of extending the company’s market reach.

By embracing the creative and innovative thinking of like-minded companies, AquaTerra has added new access technologies to its service offering; including Work Positioning Netting (which incorporates working platforms with Dropped Object Protection and general Personal Fall Protection), Cradle Systems and now QUIKDECK® - each offering its own set of unique benefits to individual work scopes.

New Technology for Topside Solids Removal and Production Optimization | Neil Meldrum, FourPhase

FourPhase has developed a new technology for topside production optimization aimed for solids removal from single wells where previously conventional desanding systems could not be installed due to the space constraints or deck weight limitations. A wellhead desander system containing new ground-breaking design, that will have its first confirmed field trial in 2017 in the North Sea, is meant for separating solids from a hydrocarbon fluid produced from a production facility to be supported on a wellhead or riser connected to a wellhead. The system comprises modular solid separators and solids collection with weight measurement and flushing units. The system allows for real time data collection of solids removed.

A wellhead desander system, containing 4 individual cyclone units, utilizes a patented desander technology with a separation efficiency of 98% down to 20 microns and is mounted directly on the wellhead of the individual sand producing wells addressing space limitations common on offshore facilities. Landing wellhead desander system on XMT removes the weight constraint related to hatch deck or other deck limitations. 4 desander vessels that are hooked up to a riser stack, with a collector adaptor on top, enable for continuous production and efficient solids removal while maintaining a minimal pressure drop.

This ultra-compact unit for installation directly onto existing XMT contains dynamic inlets giving a high flexibility and high capacity

regardless of flow, solids size, gas and pressure conditions.

The system is patent-pending.

Motivating the Market for Remote Production Efficiency Improvement, and Marginal Gains with Digital Technology | Steve Aitken, Intelligent Plant

During this talk we will discuss how Operators can make use of a cloud-based app-store of unique apps that are able to help advise on how to reduce downtime, prevent trips, and optimise production for any asset.

We will highlight the difference with the older methods and the problems that this approach addresses, and also highlight the opportunity for any vendor to make use of the technology we have to enable the deployment of their own apps – and to allow the market to easily and quickly get the gains with almost immediate pay-back for the Operator, and a steady stream of revenue for the app developer.

We will show real examples where compressors are tripping and the cause was unknown, where wells were producing inefficiently and where process upsets were previously hard to manage.

Transforming Decommissioning Planning | Pam Ogilvie, Decom North Sea

In August 2016, Decom North Sea launched the Late Life Planning Portal, known as L2P2. This online portal was the culmination of a Decom North Sea led, industry wide initiative, consisting of a variety of oil & gas operators, supply chain companies and regulators.

The portal provides a single access point for knowledge sharing and cross sector learning, ultimately driving best practice and a standardised approach to late life and decommissioning planning. Providing information and guidance which will transform the way in which the industry will approach this phase of asset management leading to cost reduction.

This presentation will provide an overview of the portal, while providing details and clarification on the definition of tools, case studies and lessons.

L2P2 is one of the best examples of collaboration our industry has witnessed to date, setting a benchmark for the future.

13.00 The Benefits of Integrated Operations at ConocoPhillips | Stephen Goodwin, ConocoPhillips

Integrated Operations (IO) within ConocoPhillips UK is an operational philosophy which places great emphasis on encouraging collaboration across the organisation to drive operational performance, reduce risk, improve efficiency and create an environment that fosters continuous improvement. A dedicated Onshore Operating Centre (OOC) was built to form the heart of the IO in the Aberdeen office servicing the needs of the assets. It is an innovative environment that delivers sustainable and tangible benefits. The real tangible benefit it has brought is a heightened opportunity for learning and development within a

16

Day 2

collective, multi-faceted team environment. The OOC has been an enabler to allow new work processes to be implemented with a strong focus on integration and collaboration between the office and the field and the functional groups.

The new organisation has helped to double the number of activities achieved offshore. We have seen a 70 percent reduction in the number of changes to maintenance plans and have witnessed a tripling of offshore tool time (the number of hours spent performing productive tasks per shift). We have also seen a 32 percent improvement in unplanned production trips, and have managed to reverse the backlog of work. Whilst the challenge to change how we worked within UK operations was kicked-off before the fall in energy prices, it has achieved early results, is continuing to deliver and it is clearly sustainable.

This presentation will provide a key insight into:

– The Integrated Operations concept

– An overview of its main functions and how they interact – Production Delivery, Maintenance & Reliability, Planning & Scheduling

– Office design and layout

– Key benefits – improved efficiency, flexible and supportive organisation

– Future developments – Onshore Control Centre.

13.20 Remote Operations: Reducing OPEX, Improving Safety and Increasing Efficiency | Chris Stone, Servelec Group

At Servelec Controls, we believe that remote operation is the most viable solution for extending the life of ageing assets, and an effective alternative to costly and irreversible decommissioning. Automating production and remote monitoring of offshore facilities is necessary to maintain the UKCS’s competitiveness.

Our remote operations solution is helping one client reduce intervention time significantly over a two year period on one specific field in the North East Irish Sea. The solution reduces risk to personnel and delivers an estimated return on investment in less than 24 months.

Servelec Controls’ solution involves removing redundant equipment and commissioning integrated systems that minimise the need to deploy interventions should a fault occur. New switchboard technology configured with intelligent circuit breakers to monitor devices and retrieve operating data such as breaker trips and wear provides a mechanism for predictive maintenance and remote reset following a trip. A typical remote operations solution includes:

– Integration of new DCS Control System to the existing ESD and F&G system.

– Provide connectivity to the field-wide communications network to enable remote monitoring, reset and start-up of relevant systems following shutdown.

– Design of low voltage switchboard.

Global also provides resource management, supply chain solutions and vendor inspection services within its portfolio.

14.10 Being Predictable and Avoiding TAR Overruns | Graeme Walker, BP

Over-running predicted TAR durations is caused by either inadequate planning or emergent operational problems either immediately prior to the TAR or during the execute phase itself. TAR teams can minimise both by dealing with the root causes, and by working with Maintenance and Operating teams effectively. Clearly there will always be some issues that arise that cannot be predicted, but ensuring TAR preparations are fully thought through, have clear contingency plans in place, and taking time to consider possible operational problems in advance each make a huge difference to the predictability of a TAR and, as a result, help avoid over-runs.

BP places significant importance on preparing for each TAR and strives to ensure none over-run. Front-end loading is critically important and the overall process to prepare for a TAR is typically 18 months. Within this, our experience is that focussing on 5 areas has a disproportionate effect on the overall predictability of a TAR – scope selection, job planning accuracy, operation team plans, schedule optimisation and execute team organisation.

This presentation will outline how BP delivers on each of the 5 areas, and will provide initial results from the 2016 TAR season that show that this approach works.

15.10 Increased Throughput Through Optimisation of Mature Assets | Eddie McPhilemy, NOV

This presentation explores the opportunities that are available to enhance the environmental and operational performance of upstream production systems, in particular focusing on bulk separation and produced water systems. The work elaborates on the use of tools and methodologies that are available to operators today to achieve a detailed understanding of fluid systems and processes.

The presentation will discuss how a targeted evaluation of the process at site allows current data relating to the rate, condition and quality of crude oil and produced water streams to be ascertained and used as a basis to identify and capitalise on opportunities to enhance system throughput. Tools such as: fluids characterisation, process review, computational fluids dynamics, physical modelling and testing are discussed and how their appropriate application help to derive a thorough and detailed understanding of process system capability and upgradability.

Using a specific case study, the work demonstrates a comprehensive process that can be used to successfully capitalise on optimisation opportunities and some example technologies that can be utilised. The case study demonstrates a successful approach used to optimise multiphase separators, defiling hydro cyclones and a produced water degasser and follows the work from field evaluation through to hardware and technology upgrade and implementation.

15.30 Maximising Volumes and Performance using Plant Models | Scott Smith, Genesis

Recent focus in the UKCS on improving uptime and maintenance performance of plants is based on the assumption that this will improve revenues. While benefits need to be realised this way, the real issue is maximising fluid volumes. This requires a focus on the dynamic behaviour of a plant and a deep understanding of the fundamental thermodynamic constraints and basis of design present. This allows the team to find the sweet-spot of a plant’s operating envelop where fluids are maximised.

Whether a reservoir is developed with subsea processing, through an FPSO or a range of different topsides, the processing equipment is sized using a simulation model which is a fundamental tool. Chemical Engineers have a key role in maximising economic recovery through effective Life of Field support; from right sizing of the process through to day-to-day troubleshooting and optimisation.

This paper outlines some of the best practise in the use of plant models and shows through case studies the value of having these fundamentals in place. Areas explored will include optimising an aging process (right sizing, control configuration), tail end production vs. cop (planning for decommissioning) and lifecycle simulation (simulation, operator training, and online systems).

15.50 A Comparative Study of Production Efficiency Improvements Between the UKCS Production Platforms and Other Global Extractive Industries | Innes Auchterlonie and Andrew Woodward, Imrandd

IMRANDD in collaboration with a number of industry bodies, plan to study the current gap between productivity improvement activity in the UKCS and initiatives taken in other extractive industries.

For many years, the mining industry has been challenged by fluctuating commodity prices and increasing costs of extraction. In order to support their slender margins, they have combined lean methodology and asset integrity management strategies. The aim has been to prevent unplanned stoppages through a mixture of maintenance, reliability and planning studies with a continuous improvement programme.

Of the 26 case studies we have looked at, we highlighted $303.5 million of benefits, both cost reductions and productivity improvements. The main focus areas that they concentrated on were:

– Maintenance supply chain

– Inspection and maintenance strategy, planning

– Management processes

– Performance measurements

– Supervisory behaviours

– Programmes of continuous improvement led by the operational workforce.

Our industry in the UKCS is now embarking on the same journey. By comparing the mining case studies with operator examples, we hope to define a road map of best practice, which will lead to high-productivity and profitability.

We took Operator data and compared their activities and savings with our mining case studies and developed a gap analysis. This will provide next steps for operators in the sector.

16.10 Defining a Long-Term TAR Strategy | Graeme Walker, BP

All assets have some sort of TAR strategy, be it thoroughly thought-through or simply based on historical norms of conducting TARs at periodic intervals. Taking time to assess the demand for TAR-dependent work, and ensuring that the work an asset commit to adds value, moves the strategy toward the former and away from the latter.

BP’s experience is that the TAR team play a vital role in creating value-adding TAR strategies. This presentation will show how this was done in BP and the change in TAR frequency & duration that resulted. It will show that the TAR team has a crucial leadership role to play to avoid unnecessarily frequent and lengthy TARs, and in driving a culture of being highly selective of work to be done during TARs when revenue is temporarily stopped.

Stands 22 to 27 on the Topsides UK floorplan

1 Problem Statement

Caissons are used in a variety of applications on offshore production platforms and vessels. Common uses for caissons are Firewater and Seawater Lift, Drain as well as I / J-Tube applications. Due to platform life extension, caissons have often been in place longer than planned, and deterioration and failure of caissons is a growing trend in the North Sea and worldwide. This deterioration and failure may present a dropped object risk to subsea structural and piping systems. Their size and location also often make them difficult to access.

2 Aims

As there are a number of caisson related issues across late life assets, GEG have reacted to the industry wide issue of caissons with a bespoke offering via our Integrated Caisson Team (ICT).

This initiative that provides a cost efficient and value added turnkey caisson solution and “one-stop” shop service.

3 Method

In an industry where innovation and collaboration are key, the ICT is a seamless approach and also offers the opportunity to have one interface and a unique commercial offering.

This ICT is made up of a number of companies with specialties dealing with caisson issues. We’ve teamed together to provide a collaborative offering, cost efficient and value added turnkey solution for caisson related scopes.

4 Impact

The philosophy behind the ICT model is the provision of a “one-stop” caisson remediation and replacement offering that identifies best value solutions by combining the services of selected ICT Partners throughout the project lifecycle.

Significant value is the ability of the ICT to offer options to a variety of solutions from within the structure of the ICT, without the requirement to bring in additional external resources.

Examples include:

– Options for either welded or weldless connections of caisson sections

– Use of conventional rigging equipment or specialist caisson lifting tools during destruct and construct

– Options to coat caissons with client specified coating systems or utilisation of one coat systems complete with coating warranties during the fabrication process

– Option to install marine growth prevention systems at time of caisson installations, or as retrofit solutions to existing caissons (this option is available to risers, conductors, and structural tubulars)

– Options for nitrox diving capability to 50m or cofferdam support in the splash zone

– Alternative access solutions including rope access, WEB deck and tension netting systems, all installed by multi-disciplined access and trade technicians
