The final two modules for the turret mooring system (TMS) for Equinor ’s Johan Castberg floating production, storage, and offloading (FPSO) vessel have headed to Singapore for integration into the FPSO’s hull.

Marine and offshore services provider Drydocks World Dubai fabricated all four TMS modules as part of contract with SBM Offshore .

According to SBM, the shipping of the last two modules represents the successful completion of their fabrication phase.

SBM Offshore senior project manager Michael Sandberg said: “We are delighted to have completed this milestone for the Johan Castberg project.

“It represents a great achievement thanks to the quality work performed by the project teams across the world, the close engagement with our client and the dedication and expertise of the yard and our vendors.”

The 8,000t bogie turret can accommodate 21 riser slots.

In the mid-April, SBM loaded the manifold and gantry modules onto the transportation vessel. It slated delivery to the Singapore yard for next month.

The Johan Castberg FPSO will operate on the Skrugard, Havis, and Drivis discoveries in the harsh environments of the Barents Sea, offshore Norway.

SBM Offshore said the turret mooring system allows the FPSO to safely remain in position on the field during weather extremes ensuring continued operations and the transfer of fluids from the seabed through the risers to the FPSO vessel.

The Johan Castberg field development is located in production licence PL 532, 100km northwest of the Snøhvit field in the Barents Sea. Field partners are Equinor (50%), Vår Energi (30%), and Petoro (20%).

Last December, Equinor and partners concluded that a downscaled ship-to-ship oil transfer terminal for the Johan Castberg field development would be too costly, and abandoned the oil terminal project for the field.
