Sleipnir to install final Johan Castberg structures

The semi-submersible crane vessel Sleipnir will soon install the manifold and gantry modules on Equinor’s Johan Castberg, a floating production storage and offloading (FPSO) vessel.

This installation will take place at the Akers Solutions quay in the municipality of Stord, in Vestland county, Norway. Both the aforementioned companies are Norwegian, with the energy company, Equinor, formerly known as Statoil, being based out of Stavanger, while the client, Akers Solutions, is headquartered in Fornebu.

In January of this year, Heerema Marine Contractors also installed the Johan Castberg FPSO’s lower turret for Akers solutions. The turret, consisting of three parts, was brought from Singapore to Stord aboard the heavy lifting vessel Trustee, arriving on January 24th, after five weeks of travel.

In 2020, the Johan Castberg’s original 8,000-tonne turret was installed by United Heavy Lift. The FPSO vessel was then transported from Singapore to Europe in February 2022, onboard Boskalis’ semi-submersible heavy transport vessel Boka Vanguard. It was delivered in April of this year. The ship is scheduled for deployment at the Johan Castberg field in the Barents Sea, in the Arctic Ocean.
