The turret mooring system (TMS) for Equinor’s Johan Castberg floating production, storage, and offloading (FPSO) vessel is en route to Singapore for integration into the vessel’s hull. Drydocks World Dubai fabricated all four TMS modules under contract with SBM Offshore.
The first two modules, the bogie support structure and lower turret, arrived in Singapore late 2019 and early 2020. The manifold and gantry modules were completed and safely loaded for transport in mid-April 2020 with delivery to the Singapore yard planned for May.
The turret is an 8,000-ton bogie turret accommodating 21 riser slots for the new-build Johan Castberg FPSO, which will develop Skrugard, Havis, and Drivis discoveries in the Barents Sea, offshore Northern Norway. The FPSO will be permanently moored in 372-m water depth by means of three bundles of five mooring lines.
Johan Castberg’s recoverable resources are 450-650 MMboe, according to the Norwegian Petroleum Directorate. The development is in PL 532 about 240 km northwest of the Melkoya LNG plant in Hammerfest and 100 km north of Snohvit field.
Johan Castberg license partners are Equinor (50%), Vår Energi (30%), and Petoro (20%).
