West Africa

Following its success in the Gulf of Thailand, Decom Engineering (Decom) has secured two contracts worth more than UK£300,000 in the North Sea and offshore West Africa, strengthening their reputation as a leading provider of decommissioning services.

The northern Irish company had designed and developed a range of cold cutting saws which are deployed on a variety of energy sector decommissioning projects which require pipelines and associated infrastructure to be safely removed.

The UK Continental Shelf contract is a conductor recovery and removal project deployed topside on a vessel and Decom’s C1 Chopsaw is expected to complete eight cuts on behalf of a global offshore contractor. Separately, Norwegian-headquartered subsea and offshore wind farm contractor Havfram have commissioned Decom to carry out cutting operations on a ROVCON connecter in water depths of up to 800 metres off the coast of West Africa.

Both projects were secured following a series of technical trials at JFD Global’s testing tank and the National Hyperbaric Centre in Aberdeen, and they follow the successful completion of two phases of another international workscope offshore in the Gulf of Thailand in which Decom’s chop saws performed hundreds of cuts on piping of up to 16” diameter.

Decom Engineering Managing Director, Sean Conway, commented, “The successful completion of a strategic project offshore Thailand and our imminent mobilisation on workscopes in the North Sea and Africa, demonstrates that our technology is gaining traction with energy companies and contractors who have technically challenging requirements on a range of international decommissioning projects.

“Recent technical trials in Aberdeen have proven our cutting technologies can operate safely in deeper waters and that they are preferable to rival solutions where accessibility to subsea infrastructure is an issue.

Steven Gibson, Senior Engineer with Havfram during testing, remarked, “The potential of Decom’s saw to cut the heavy grade material we are going to be cutting through on the West African seabed, the speed of the cut, and the ability to position it in a very restricted space, were the driving factors in awarding this workscope.”

Decom opened up a new base near Aberdeen at the start of 2022 to be located closer to potential North Sea clients and the policy appears to be paying off following this most recent contract award.

Conway added, “We will continue to invest in infrastructure and to build our asset portfolio to ensure we are positioned to be able to respond to more technically challenging projects as the global decommissioning sector continues to grow.

“Our R&D and engineering teams are currently working on new chop saws which are capable of handling piping of up to 36” diameter in anticipation of potentially winning other contracts in the second half of this year.”

BiSN, a leading supplier of sealing solutions and technology to the global oil and gas industry, has reached a significant milestone after completing its 300th deployment, helping operators around the world to effectively solve common downhole flow issues.

The operations were carried out on six continents (Australia, The Americas, Europe, the Middle East, Africa and South Asia) and took place in a range of challenging conditions and location; onshore, offshore, high temperature or high pressure.

By providing critical production enhancement, intervention, completion, and plug and abandonment services, using its patented Wel-lok sealing technology, BiSN reduced costs, improved production, and dramatically extended the life of hundreds of wells.

By working with specially developed chemical reaction heaters to carefully melt unique bismuth-based eutectic alloys into plugs, BiSN developed its Wel-lok technology to create a bismuth plug that is not only safer, but much more reliable and easier to deploy. It makes it possible to form a gas tight (v0) seal and with a density that is 10 times higher than water it effectively displaces all wellbore fluids.

Paul Carragher, CEO of BiSN said, “As operators strive to address downhole flow issues safely, increasing production while reducing costs, we have made it our mission to help them achieve this. We have the extensive real world experience in applying this method. As a result of carrying out more than 300 deployments globally, we know how to successfully use our technology to complete operations aimed at enhancing production, completions, plug and abandonment, and intervention. These jobs represent operations carried out for many repeat customers, illustrating the value and confidence they continue to place in our work.”

To help operators tackle complex challenges downhole, BiSN draws upon its varied experience and services. These range from shutting off water production and isolating zones to setting a gas-tight plug, repairing damaged casing or tubing, and permanently sealing multiple annuli, among others.

While the company continues to provide downhole sealing solutions to new and existing customers in the US, Canada and Australia, BiSN is actively expanding in Europe and Africa and has recently opened an office in Aberdeen.

Petrofac, one of the leading providers of services to the global energy industry, has grown its presence in Africa having been selected by Tullow Oil to provide well decommissioning services in Mauritania.

The contract, with a potential total value of more than US$60mn, involves the project management, engineering, planning and plugging and abandonment (P&A) of seven subsea wells on Tullow Oil’s Banda and Tiof fields.

Petrofac will assume responsibility for the subsea well decommissioning scope from Maersk Decom, who have been preparing the work since 2020. By mutual agreement, the parties have novated the contract to Petrofac who will take immediate responsibility for the project, with the offshore scope running from the fourth quarter of 2022 throughout first quarter of 2023.

Petrofac said it will provide all personnel, assets and equipment required for the project, including management of the ‘Island Innovator’ drilling unit and offshore support vessels.

Nick Shorten, Chief Operating Officer for Petrofac’s Asset Solutions business said, “The contract award is a demonstration of the international demand that exists for the skills and quality of delivery we have established in the North Sea. Since 2016 Petrofac has delivered three successful decom campaigns for Tullow Oil. We look forward to emulating this success for them in Mauritania, and across the African continent as we continue to grow our business here.”

Havfram, a Norwegian oil field equipment supplier recently announced that PC Mauritania 1 Pty Ltd, a wholly-owned subsidiary of PETRONAS, has awarded Havfram an offshore decommissioning contract.

The contract includes the provision of engineering, procurement, retrieval and disposal (EPRD) services for the abandonment and decommissioning of Subsea Facilities at Chinguetti and Banda Fields, offshore Mauritania, in March 2022.

“The PETRONAS Chinguetti and Banda EPRD project is another significant project award for Havfram in the Africa region. This is one of four projects Havfram has been awarded in Africa and the Mediterranean in the last 12 months, further enhancing our already strong track record in the region. We are proud to have been chosen by PETRONAS to meet their decommissioning needs in this field,” said Odd Strømsnes, CEO, Havfram.

Under the contract, Havfram will utilise its in-house expertise to project manage, engineer, retrieve and dispose of the remaining field infrastructure, having already executed the first phase of decommissioning operations in 2018.

“Our focus on risk mitigation and efficient execution solutions has seen us selected by Petronas once again as the perfect partner for decommissioning operations,” said Kevin Murphy, EVP Subsea and Deputy CEO, Havfram. “Havfram has consistently delivered a range of subsea projects across the continent for our clients, and we look forward to renewing our working partnership with Petronas’ Chinguetti and Banda team.”

Andrea Sbordone, Business Development Manager at TechnipFMC, will describe four case studies of successful riserless light well intervention (RLWI) campaigns at the upcoming Offshore Well Intervention West Africa 2022 conference in Accra.

David Carr, Senior Vice President – International at Helix Well Ops, will be hosting a session at the upcoming Offshore Well Intervention West Africa (OWI WA) which will look at the potential for light well intervention (LWI) in Africa.

Exclusively for attendees of the event, which is arriving in Accra from 12-13 July, Carr will examine examples of innovative LWI vessel based solutions for complex well integrity issues and production enhancement purposes that improve the efficiency of well intervention projects.

Despite the seemingly incredible benefits that can be achieved through the use of such vessels, there remains somewhat of a reluctance to make use of them in the West African region. However, with Covid-19 forcing oil companies to keep hold of capital wherever they can, LWI could provide a viable outlet by offering them the chance to achieve their offshore objects but at a much lower cost.

Carr will continue the session by reviewing multi-service campaigns completed on an integrated vessel and how this can solve a variety of challenges operators face when embarking on intervention projects.

Those attending OWI WA will then have the chance to engage in a discussion with the Helix representative to explore how collaboration with an international and multi-disciplinary team can lead to seamless operational efficiency.

Such unique sessions are not to be missed by anyone involved in the African offshore industry or those interested in squeezing more from their offshore operations. To learn more, be sure to download the event brochure here:
