Heerema Marine Contractors has completed the installation of the Hugin-B jacket, the fifth and final jacket for the Yggdrasil and Valhall PWP-Fenris project for Aker BP ASA.

The latest operation followed the installation of the Fenris jacket in 2024 and the Valhall PWP, Hugin-A, and Munin jackets in 2025. With Hugin-B now installed, Sleipnir has completed the jacket installation scope referenced by the company for the project.

The Hugin-B jacket weighs around 4,500 tonnes and stands 146 m tall. It was towed from Verdal, moored against Sleipnir, lifted, upended and carefully set down on the seabed. The installation was completed through pile driving, grouting and completion activities.

Heerema Marine Contractors described the work as a heavy lift operation carried out from start to finish through step-by-step execution, supported by offshore and onshore teamwork.

The company added that Sleipnir is not yet finished in the Yggdrasil field. Four topsides and two flares are still scheduled for installation.
