Aquatic Engineering & Construction has been sub-contracted to Bibby Offshore to replace subsea infrastructure as part of BP’s $1 billion Eastern Trough Area Project (ETAP) life extension project.
Aquatic will deploy its carousel system to install 35 kilometres of umbilical ensuring electrical control capability between ETAP’s central processing facility and the Machar field.
The umbilical laying work is scheduled is expected to last approximately 30 days. This is the first phase of Bibby’s five vessel campaign, involving trenching, structure and riser installation followed by electrical diagnostics and commissioning works.
Aquatic – part of the Acteon group – has also been subcontracted to provide lay equipment and personnel for the riser installation campaign in September of this year.
ETAP, located 150 miles east of Aberdeen, is one of the largest and most complex developments in the North Sea, comprising nine oil and gas reservoirs, six of which are operated by BP. The life-extension project will help secure the future of the fields until 2030 and beyond.
Aquatic will be providing a team of offshore supervisors and technicians to mobilise and operate its 1,500-tonne on-deck carousel and integrated five-tonne tensioner system, as well as a 15-tonne two-track tensioner and ancillary equipment.
Additionally, James Fisher Offshore will provide a 20-tonne abandon and recovery winch to support the operation. Significantly, the Aquatic offshore team will manage and operate the JFO equipment, thereby reducing the number of back-deck personnel hitherto required during the month-long operation.
Aquatic will be the sole point of contact for the customer in supplying and managing the back deck equipment portfolio for this project.
Aquatic hosted a two-day event prior to the mobilisation, using this North Sea opportunity to bring specially invited customers, shareholders, media, partners and employees to Smith Quay in Peterhead, Scotland, to see the carousel first hand before operations commenced.
Steven Kilpatrick, Aquatic’s Regional Manager, Europe, said: “With Aquatic’s 1,500-tonne modular carousel mobilising out of Peterhead, we decided this would be an excellent opportunity to bring together our stakeholders from across the region and provide a demonstration of its capabilities
“In the current economic climate, many leading oil and gas providers are taking the opportunity to reinvigorate areas of their fields that need more specialist operational support and we are engaged in a number of these new North Sea opportunities.”
