The projects have been diverse – with our multi-discipline capabilities coming into play – often complex and undoubtedly fulfilling. You can see a taster of our international reach in this edition of Xtra.

We are also proud to have welcomed a new investor this year, showing great confidence in our future plans. Subsea 7 has come on board with Chiyoda Corporation of Japan also retaining an interest in Xodus, to further enhance our capability whilst we continue to provide independent engineering and advisory services to the energy industry.

We increased our engagement with Asian E&P clients after we welcomed Chiyoda as a shareholder in 2013 and now look forward to further enhancing the development of Xodus, with a robust plan in place to grow key areas of our business.

This year has also brought resurgence in front-end engineering projects as markets demonstrate further recovery and you can read about some of our recent field development work (page 3). Demand for decommissioning, subsea and environmental services has enabled Xodus to recruit more specialists in recent months and we are also hosting open days to attract new graduates across our offices.

We continue to have a focus on innovation and our XAMIN tool (page 13) is a perfect example of how we intend to provide more efficient ways of working to our marine renewables clients. We will be showcasing this further at All Energy this month.

We are also continuing our long-standing relationship with Apache in the North Sea with the award of two projects. The first project is the conceptual design and FEED work associated with the Storr development. The Storr field is a single well, gas condensate development planned to be tied back to the existing Beryl Alpha platform.

We will initially complete a conceptual assessment to streamline the options under consideration before embarking on the FEED for the selected option. The scope includes subsea pipeline design, flow assurance, materials and corrosion engineering coatings selection and structural and environmental support. The second award was for subsea engineering associated with Apache’s Seagull development. We previously completed the concept selection phase of the development and this new award takes the design of a planned tieback to the next stage. Like Storr, the scope includes pipeline engineering, materials and corrosion support, manifolds and structures engineering and environmental impact support.

We have also won work with Woodside Energy (Senegal) B.V to investigate the topsides design concept required for a redeployed Floating Production Storage and Offloading (FPSO) facility at the Rufisque, Sangomar and Sangomar Deep (RSSD) blocks located offshore in Senegal, West Africa.

This award followed earlier field development architecture studies we performed for Capricorn Senegal Ltd (Cairn) to identify and develop the field architecture for the deepwater SNE oil field. In this new study, we determined the optimal topsides configuration and operating conditions for the FPSO.

Further success in Japan, Australia and Africa brought the total to £5million, including work outside of oil and gas.

“At Xodus, we are constantly looking at ways to improve operations and reduce costs for our clients. The 10,000th assignment is a significant milestone for the company and was hard to imagine when the company launched more than twelve years ago. Dana is one of our longest relationships so it’s nice it was with them. We can now look ahead to the next 10,000.”

We caught up with her to find out more about her role.

What does your role involve? I manage a dedicated in-house compliance team where we prepare and manage all environmental application types, ensuring that we deliver high quality and technically accurate applications, mainly for the oil and gas industry. We currently provide a significant proportion of permit applications in the UKCS (approximately 30-35%).

I manage a team of 14 and one of the unique attributes to the team is that we have been able to retain a significant proportion of senior personnel who have worked in compliance since the onset of key legislation and industry standards. We have grown with the changing requirements of the regulator, from Petroleum Operations Notices (PONS) to the current Oil and Gas permit system – Portal Environmental Tracking System (PETS).

In this respect, we are a highly experienced with exceptional technical knowledge of compliance processes and data requirements. The experience gained from the same personnel working with many operators since the onset of legislation provides Xodus with a unique understanding of changing regulatory expectations.

My main role is to manage a range of compliance projects, provide technical and legislative advice to both clients and internal staff, provide training, implementation of compliance procedures and guidance documents to both clients and for internal requirements.

I also undertake compliance audits, business development and recruitment for the company and provide environmental advisors on secondment.

What are the main challenges of securing a UKCS permit? One of the main challenges to ensuring a fast approval process of a permit by the regulator is understanding the current environmental data requirements. The experience gained from working with many operators provides us with a unique understanding of industry requirements and any problems or issues faced.

We document any regulator or statutory comments that we receive in our regulator comment database and this central database of comments increases consultant efficiency time in preparation of permits which has led to a decrease in the number of comments received. We have an enhanced understanding of regulator wide expectations and are applying these to the permits we prepare, and this ultimately has allowed timely approval by the regulator.

Are permits constricted to offshore work? Although we undertake a considerable number of offshore permits and consents, we do have the expertise and capability to provide nearshore and onshore compliance support. These can include, but not limited to, marine licence applications for renewables and cable laying. Also, works licence applications which are carried out within harbour or port limits, controlled activity regulations (CAR) required for SEPA and EU ETS and PPC permits.

At what stage should a company approach Xodus about compliance? At the very latest, permits require two to four weeks of preparation time so ideally two months prior to operations. However, for planning purposes, it is preferable that we gain an understanding of the projects as early as possible in the process, particularly for larger and more complex developments. This allows our teams to provide support and advice upfront to ensure that all aspects are considered and there is a good understanding from our clients on the process and data requirements.

Why should businesses come to Xodus? We have a flexible team and are dedicated to meeting our client’s needs with specialists in production, wells, subsea, geophysical, atmospherics, renewables, cable laying. Our clients are extremely satisfied with our approach to compliance management and this is demonstrated through our long-standing relationships with many clients. We pride ourselves in providing a high quality, value for money product, producing well-written, easy to read, visually appealing public documents. We have a pro-active independent relationship with the regulator and statutory consultees allowing a clearer understanding of comments which ultimately improves the overall approval process. We also continually strive to look for ways to make our processes more efficient and have developed innovative tools to support the team and our clients.

Large deals of note in the last three years:› At the end of 2017, ExxonMobil paid Eni $2.8bn for a 25% stake

in the company’s Mozambique gas resources, a move by the company to firm up its LNG future strategy. Having ExxonMobil as a partner in this type of resource base is a solid move by Eni and should help them reach commercialisation sooner.

› In Q3 2015, Sonangol and Cobalt signed an agreement for Sonangol to acquire Cobalt’s 40% participating interest in blocks 21 and 20 offshore Angola for US$1.8bn. The blocks contain commercial reserves of approximately 800 MMbbl.

Significant risks remain in Africa including operational issues,access to infrastructure as well as political concerns, however, most areas have seen improvements over the past few years. These improvements, coupled with converging buyer-seller valuations driven by improved oil price stability, is anticipated to lead to increased activity in Africa in 2018 and beyond. This stability is giving potential buyers confidence to make longerterm assessments about asset value, and seek opportunities they see in the ‘new normal’ $50-$70 oil and gas future. Perhaps surprisingly a continued rally in oil price towards$100 may in fact decrease levels of M&A in the short to midterm as buyer-seller valuations could diverge leading to delays in decision making until stability is realised.

We expect M&A activity in Africa to increase as 2018 progresses and into 2019 with more money coming in from overseas, particularly from large PE houses. The challenges associated with valuing oil and gas developments in Africa (particularly sub-Saharan) are not often subsurface driven. The barrels are there, but dealing with the surface issues and export routes is often the key to understanding the true value risks and drivers.

Transactions in Africa can be complex, requiring multiple technical and commercial advisors. Our advisory team can integrate across subsurface and surface identifying the key risks and translating this into commercial advice, underpinned by technical understanding. We can provide a holistic view capturing the full development lifecycle to our clients from the sand face to point of sale, but through a single interface. Not many companies can say that.

By challenging the status quo, asking the difficult questions and combining insights from all types of businesses and disciplines from data science all the way through to organisational psychology, we can help shape the future of oil and gas in Africa.

AfricaAdvising Africa’s M&A activity

May 2018

Africa has seen relatively subdued M&A activity over the last three years (see image). In part due to the low oil price environment but even when compared to the rest of the world over the same period, the $15 billion total is modest. Also notable is the fact that the big deals of 2015-17 mostly came from corporate sources, with only ~10% sourced from private equity (PE) companies.

Salah Farid Tantawy joins from PICO Petroleum Integrated Services where he was most recently project general manager for the Amal-C platform installation in the Gulf of Suez. Salah has 37 years’ experience working in oil & gas, having started his career as a project engineer. Before moving to PICO, he was chairman assistant (VP) for projects with Gulf of Suez petroleum (GUPCO) – BP’s JV for oil production in Egypt.

Salah said: “Xodus has gained a strong reputation within the country over the last few years so I know I am joining a very experienced team with capabilities throughout the lifecycle of an asset. I hope my experience in managing multimillion dollar projects and my knowledge of the Egyptian oil and gas sector will help in attracting new business as well as reinforcing already established partnerships.”

Since 2013, we have won over £2 million in contracts in Egypt. Much of that work was previously won and carried out by the Aberdeen and London offices, however research found that an established base was required to increase business in the country.

The new office is located in the Maadi district of Cairo, which is central to many oil and gas company operational headquarters.

Managing Director, Steve Swindell said: “Over the last five years we have been collaborating with international and state organisations in developing upstream projects and increasing value of their assets. During this time, we have undertaken many scopes ranging between FEED work, advisory services, engineering studies and operational asset support assessments for major and independent oil and gas companies.

“Such a track record has established our reputation within the Egyptian market as a reputable and competent consultant. With the addition of Salah and a new office it means we can engage with clients and deploy our services quicker which we hope will lead to us gain considerable new business.”

We have delivered a decommissioning and abandonment study for wells, surface and subsea facilities in Tunisia on behalf of Thyna Petroleum Services (TPS).

We developed a decommissioning cost estimate for four onshore fields, one offshore field and two onshore storage and processing sites. The six-week study provided a high-level risk and opportunities assessment and reviewed regulatory and environmental aspects for facility and infrastructure removal.

The scope of work also included the creation of an asset register, the development of an abandonment strategy and site remediation in line with current industry best practice and in-country regulations. The study allows the joint venture partners

to define their cost liabilities towards decommissioning as well as a timeline for the project.

Tunisia and North Africa are growing areas for decommissioning. Last year, we delivered a similar scope of work for a large offshore complex in Tunisia. We also performed a study of decommissioning procedures in Tunisia compared to the North Sea – understanding the regulatory regimes and execution practices to include in cost estimates and methodology.

Managing Director, Steve Swindell said: “This project was a success as result of the support the TPS team has provided through the project team and close interaction with the Xodus project team. We have conducted similar types of work in the region and this experience was vital in advising TPS with this important project. Our integrated decommissioning capability means we can offer practical knowledge and experience of the regulatory framework for decommissioning, as well as cross-discipline technical safety and environmental support, integrity support and cost modelling expertise.”

Mr Nizar Taga, TPS finance manager said: “The study achieved the objectives set out and Xodus’ project team was successful in applying its deep understanding of decommissioning to inform the JV partners the key drivers that can materially impact the overall decommissioning cost and schedule. Xodus highlighted the risks and mitigation strategies that, if implemented, would reduce several of the inherent uncertainties associated with decommissioning a multi-asset field.

“There was a tight schedule for the work with uncertainty over data which Xodus successfully overcame through use of in-house tool. We are very pleased that Xodus had the capability and expertise to deliver this quality work to the partners requirements.”

The Asia-Pacific (APAC) region has had significant success in the growth of its decommissioning business, both in Australia and South-East Asia, where we have established relationships with several key players. We have also enhanced its digital production optimisation and monitoring tools.

With the success, our workforce has grown locally and Simon Allison is operations director for the APAC region.

Simon is responsible for the management of the group’s office including business development and growing strategic new markets while also maintaining an active technical role in projects, including project management.

Mr Allison has worked in the oil and gas industry for more than 20 years after graduating with honours in Chemical Engineering from the University of Melbourne. After starting his career as a process engineer, he later specialised in the field of flow assurance.

“It’s a huge honour to lead the APAC team in Perth and we have had an excellent year with some significant contract wins and the addition of new members of the team,” Simon said. “We continue to grow and enhance our digital production optimisation and monitoring tools.

“Over the next few months, we’re targeting sustained and supported growth while increasing our offering in the company’s core business areas of advisory service, field development, projects, asset support and decommissioning.”

Digital Asset Manager, Andy Jones, will be presenting with Origin Energy on ‘The effective use of data analytics in an advanced compressor performance and degradation monitoring’ at the APPEA 2018 Conference and Exhibition in Adelaide on Wednesday, May 16.

We have signed a three-year framework agreement with North Oil Company to deliver a variety of work for Al-Shaheen, Qatar’s largest oil field.

“This agreement will allow us to build on our experience with Al-Shaheen and increase our integration with Chiyoda. Chiyoda Almana, the Qatari entity, will support us in pre-FEED activities.”

Positive vibes in the Middle EastWork is on the up again for the vibration team in the Middle East. Over the last six months we have been supporting the likes of Zadco, ADNOC, Tebodin, NOC, Oxy Qatar and Qatargas on various projects. The vibration team is also expanding into the Asia Pacific region through a tie-up with SVTT. Since the first business development visit, six proposals have been submitted to date.

We have liaised with operators and test centres to develop functionality such as Geographical Information Systems (GIS) during this development stage. XAMIN was initially developed to provide high-level services for major oil and gas operators in the North Sea and was well received from within the sector.

For one operator, the introduction of XAMIN allowed it to cut its traditional Pipeline IM budget by 25% and free up the engineers to focus on reducing the risk picture of the asset. We believe the renewables sector can learn lessons from the oil and gas industry where poor data management is causing problems when identifying component condition or proving life extension.The tool can now provide operational integrity management for offshore wind, tidal, wave, structures and cabling. It can be used

to schedule inspections and maintenance activities, capture results for future trending, assess anomalies and assign actions for remediation during future campaigns.

Mike Allan, senior consultant said: “As a lifecycle asset tool, we believe XAMIN will benefit renewable projects, capturing design, installation, testing, operating, inspection and decommissioning information in a single system. This will reduce data losses, increase efficiency of data access, improve visibility of integrity issues and importantly for developing technology, allow issues to be identified quicker. Within the operational phase XAMIN can collate all information being measured on the asset and cross reference to allow a complete picture of operability and integrity. Once collated, data can be used to benchmark design assumptions and reduce safety margins or increase field life.

Richard Knox, Managing Director, EC-OG said: “We believe controlling operations and maintenance costs will be a big challenge to the marine renewables sector and it’s something we have considered throughout the early stages of developing our Subsea Power Hub technology. XAMIN has the potential to help us, and the industry as a whole, with its powerful combination of information on demand and established integrity processes.”

XAMIN can adapt to work with the functionality and requirements of each individual asset. It can be developed to fit with the processes of the company that requests it rather than forcing engineers to adapt their methods to fit within rigid software.

Toolsets XAMIN-ing a new sector

We have completed our initial project with Scottish Enterprise to develop our integrity management software tool, XAMIN (Xodus Asset Management and Integrity Network) for all clean energy technologies and extend the functionality to capture and monitor live data from offshore marine renewable assets. The funding has allowed us time to gain insights and feedback from industry to ensure that the product meets the needs of the users.

The ambition for this agreement is to secure funding and establish a commercially viable tidal energy demonstration project of three to eight turbines in the country. We visited Japan earlier this year to meet with government departments, supply chain and utility companies to promote the collaboration and join the lobbying effort for the general promotion of tidal energy as a credible future energy source in Japan.

Atlantis is a global developer of renewable energy projects with more than 1,000 megawatts in various stages of development including the world’s flagship tidal stream project, MeyGen. We played a pivotal role in the creation of the environmental statement as lead consultant in the environmental impact assessment for the project.

Pete Tipler, Principal Consultant at Xodus Group said: “Over the last few years, have built up strong connections in Japan through Chiyoda and we look forward to progressing this opportunity with Atlantis. We have a long and trusted relationship with Atlantis from the early days of their turbine testing at the European Marine Energy Centre (EMEC) and through the MeyGen project and can rely on the experience of their team to understand the opportunities and challenges of developing a tidal project in Japan. Together, we need to prove tidal energy as a competitive renewable energy source for the country.”

Tim Cornelius of Atlantis Resources added: “We are looking forward to working alongside Xodus pursuing development opportunities in this exciting market. This is a continuation of our long established relationship over many years at the MeyGen project that has seen the tidal stream sector move from demonstration to operations of commercial scale arrays. We look forward to replicating this success and have already commenced pursuing several project opportunities in Japan together.”

Renewables Targeting Japanese tidal opportunities with AtlantisWe have signed a Memorandum of Understanding (MoU) with Atlantis Resources to pursue the development of a tidal energy project in Japan.

We have recently completed work on the design verification of two refined product transportation systems to and from offshore SPM buoys via a subsea pipeline end manifold (PLEM).

Our recommendations resulted in the redesign of the control system and the cause and effects which eliminated the need for offshore surge accumulation tanks and relief valves. By looking at the failure elements from an operations perspective, we could prove all credible failure scenarios within the maximum allowable surge pressure.

We worked with a marine breakaway coupling supplier to specify the design of the coupling to prevent breakaway events over pressuring the floating hoses while providing an ALARP design for oil spilled in water.

The client was “very happy with the approach Xodus took and the solutions delivered”. This project is a great example of where our understanding of system dynamics led to lifecycle cost savings and environmental benefits.

New capabilitySurge analysisWorking together with an integrated project team, including the client operations team and a naval architecture design contractor, we have developed a market leading transient surge analysis capability for Marine Buoy Offloading systems.

The IRIS-M Motion Amplification System consists of a highly specified video camera and a PC-based controller and capture device. The software package allows standard recorded video images to be amplified, revealing the detail of vibration which cannot be seen by the naked eye.

Vibration magnitude and frequency can be captured from any point in the image allowing non-contact vibration measurements to be made from significant distances away from the subject.

The system can be deployed and data recording can start within minutes of a problem being identified, saving significant time and costs associated with constructing scaffold access platforms and/or organising rope access to difficult locations.

The IRIS-M Motion Amplification System is a fantastic addition to the comprehensive suite of vibration measurement devices available to our vibration engineers.

For the assessment of a wide range of common machinery problems the system is very powerful and in many ways unparalleled.

For the assessment of pipework integrity however, careful consideration must be given to the data capture aspects and to the interpretation of the data. As with so many things in life, the results are only as good as the user.

Vibration Cost saving device added to tool boxOur vibration engineers have added a powerful new motion visualisation capability to their suite of vibration assessment tools.

I first got involved with P&O Cruises in 2005 whilst working at a previous consultancy. One of the two 20MW 80 tonne electric propulsion motors on its round-the-world Aurora cruise ship started to exhibit high vibration levels and I was mobilised to investigate the problem. After several modifications to the internal wiring, the vibration could not be reduced and the cruise was cancelled and the ship went into refit to have two new replacement propulsion electric motors (PEMs) installed. After refit, I was involved in the acceptance sea trials of the new PEMs to baseline the new vibration characteristics.

Four years later, an online condition monitoring (CM) system was designed and installed by Gordon Strang and Farouk Azzaz to continuously monitor the vibration, with alarm levels set. Since the installation of the condition monitoring system, Gordon and I have been mobilised several times to investigate the vibration levels, which have exceeded the alarm levels.

Most recently, the staff electro-technical officer on board MV Aurora contacted me via LinkedIn to ask if I was still involved in vibration troubleshooting and mobilised me to investigate the reason for the current high vibration levels on the Port PEM compared to the Starboard PEM. Myself and Roger Kinns from RKAcoustics mobilised with a 16 Channel Dewesoft data acquisition system to Cartagena on the north coast of Colombia in February to board MV Aurora and monitor the vibration whilst sailing to Aruba. The Dewesoft system was set up to record the vibration levels on both propulsion motors during a defined testing program which covered the full operating speed of the motors (30 to 140 RPM). Analysis of the recorded data from both PEMs highlighted that the Starboard PEM had similar vibration signatures to those from the acceptance sea trials in 2005, but the Port PEM had discrete frequency components which are now substantially higher at 2f0 and 4f0 where f0 is the AC supply frequency.

Our recommendation was that the root cause was most likely due to torque perturbations which could happen if one (or more) of the stator bars had developed increased resistance or even gone open-circuit. P&O followed up with a full internal inspection of the Port PEM and located the problem. An open circuit coil ring was found on the NDE along with two further connections showing heat damage. The feedback was positive – “your equipment and expertise got it right!” – and we were praised for finding the issue and managing to resolve it swiftly. It’s not all oil and gas for the vibration team!

Dragados UK has awarded Xodus a contract to monitor noise levels as part of the Aberdeen Harbour Expansion Project. The £350 million development will create additional facilities and infrastructure in Aberdeen’s Nigg Bay, to the south of the existing harbour. This marks the first contract between Xodus and Dragados UK, one of the major infrastructure developers.

We have installed four remote noise monitors in the area surrounding the development, which will monitor noise levels continuously throughout the three-year construction phase of the project. The devices will automatically send alerts to project stakeholders if limits are breached. We will also provide support and consultancy services to the project throughout the three-year project span.

Noise Sound project at Aberdeen Harbour

IN BRIEF

Following a period of research and development in 2017, our geographical information services (GIS) and technical, safety and risk (TSR) teams have developed a new combined service to risk assess potential ship collisions.

This will consist of a vessel traffic survey (VTS) and collision risk assessment (CRA), drawing upon our significant in-house experience in the fields of risk assessment, vessel management and geospatial data processing.

Market opportunities for this type of service range from informing early stage design to establish structural tolerances through to permitting and consenting, where such assessments are a fundamental requirement for locating offshore assets (e.g. drilling rigs) in UK waters under the Energy Act. Since developing this offering, we have already delivered VTS for an offshore wind project in the North Sea and an FPSO project off West Africa and a full VTS/CRA scope for a multi-asset oil and gas development in the Southern North Sea.

Whilst VTS/CRA is not a new offering to the industry, the approach we have developed is robust, transparent, cost-competitive, and highly integrated with our engineering and permitting teams, differentiating us from the competition.
