EnQuest, a London Stock Exchange-listed energy firm, has tucked a new decommissioning milestone under its belt in the UK sector of the North Sea, thanks to the assistance received from a heavy lift vessel owned by Allseas, an offshore pipeline installation, heavy lift, and subsea construction contractor.

Following regulatory approval in May 2020, the firm awarded the Heather topsides removal contract in September 2022 with a single lift operation scheduled for 2025. The Heather jacket removal scope was subject to a separate process.
