Aquatic Engineering & Construction Ltd. has been subcontracted by Bibby Offshore Ltd. to replace subsea infrastructure in the Central North Sea as part of BP’s $1 billion Eastern Trough Area Project (ETAP) life extension project, according to a news release.

Aquatic said it will deploy its carousel system to install 35 km of umbilical ensuring electrical control capability between ETAP’s central processing facility and the Machar Field, the release said. The umbilical lay campaign is scheduled to begin in June and is expected to last about 30 days. It will mark the first phase of Bibby’s five vessel campaign, involving trenching, structure and riser installation followed by electrical diagnostics and commissioning works.

Aquatic has also been subcontracted to provide lay equipment and personnel for the riser installation campaign in September, according to the release.

ETAP, located 240 km 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 ETAP Life Extension Project (ELXP) will help secure the future of the fields until 2030 and beyond, the release said.

Aquatic said it will provide a team of offshore supervisors and technicians to mobilize and operate its on-deck 1,500-tonne carousel and integrated five-tonne tensioner system, as well as a 15-tonne two-track tensioner complete with all ancillary equipment. Partner James Fisher Offshore (JFO) will be provide a 20-tonne abandon and recovery winch to support the operation.
