United Heavy Lift moves 8,000-tonne turret

United Heavy Lift has safely moved an 8,000-tonne turret for Equinor’s new Johan Castberg FPSO. The turret is designed by SBM Offshore and will now be shipped from Drydocks World Dubai to Singapore where the FPSO is being constructed. The load-out was carried out by Mammoet. 

The 8,000-tonne Bogie Turret will allow the FPSO the operate in the harsh conditions of the Barents Sea offshore Northern Norway, where Equinor is developing its three new discoveries called Skrugard, Havis and Drivis.

The FPSO will be permanently moored in 372-meter water depth by means of three bundles of five mooring lines and the turret will keep the FPSO in position while transferring fluids from the seabed via the risers to the FPSO.

Drydocks World Dubai (DDW) fabricated all four modules for the Turret Mooring System (TMS). The first two modules, the bogie support structure and the lower turret, were completed in 2019 and delivered to the Singapore yard in 2019/2020. The manifold and gantry modules were completed and safely loaded onto the transportation vessel in mid-April, and delivery to the Singapore yard is planned for in May.

United Heavy Lift deployed its semi-submersible heavy transport vessel MV Hua Sheng Long for the operation. The vessel is currently sailing Northeast of Oman and is expected to arrive in Singapore on May 10th.

The German shipping company operates a fleet of five of these semisubmersible vessels which per May 1st will be managed through the company’s new subsidiary United Heavy Transport.

“Given the additional challenges under today’s exceptional circumstances worldwide, delivering this key milestone as planned is an outstanding performance by all involved,” commented Laurent Agussol, SBM Offshore Turret & Mooring Product Line Director.
