Maersk Supply Service has secured a second decommissioning contract with Maersk Oil UK; this time for the Leadon subsea decommissioning in autumn 2017, off the Shetland Islands.
The company’s first decommissioning contract with Maersk Oil, for the Janice subsea field in the North Sea, was revealed in September 2016. According to the company, the Janice decommissioning project has progressed on time and as planned since the beginning in summer 2016.
To date, Maersk Supply Service, said it has removed and delivered the Janice floating production unit (FPU), recovered all subsea risers and sunk the mid-water arches on the seabed in preparation for a rig to begin the plug and abandonment phase of the project.
The next phase of the Janice decommissioning will employ the company’s first of six Starfish newbuildings that are built for deep water anchor handling and oilfield operations.
“Securing the Janice as well as the Leadon contracts shows that Maersk Supply Service is a trusted partner when it comes to delivering projects with broader scopes of work and responsibilities. Through managing project partners and leveraging our internal capabilities we are able to deliver a more simplified, cost effective and safe project solutions for our customers,” said Maersk Supply Service CEO, Steen S. Karstensen.
Building on the collaboration established in the Janice decommissioning, the same Maersk Supply Service-led team will begin work on the Leadon subsea field in autumn 2017. Project planning for the Leadon decommissioning is already underway and up to five Maersk Supply Service vessels, including the Starfish new-building from Janice and one of the Stingray subsea support vessel new-buildings, are expected to be used in the project program.
Located 120 nautical miles off the Shetland Islands, the Leadon subsea structure sits at approximately 120 meter water depth and the subsea structures to be recovered weigh up to 397 tonnes. The project completion is expected in December 2017.
