Heerema´s Sleipnir Installs Jacket for the Hollandse Kust Zuid Wind Farm
Heerema’s SSCV Sleipnir has successfully transported and installed the six-legged, 2,852 metric ton, and 50-meter long jacket for the Hollandse Kust (zuid) (HKZ) offshore transformer platform.
Heerema secured the contract for this project with the jacket and topside main contractor, Petrofac. While the HKZ windfarm developer is Vattenfall, and the transformer station is owned by the Dutch grid provider TenneT.
Koen van der Perk, Heerema Wind Director said: “We are proud to work alongside these parties to contribute to the energy transition in the Netherlands. With our main office located in Leiden, the Netherlands, this project was special to execute so close to home, with visibility from the shore.”
The project is Sleipnir’s second on the HKZ project, with the installation of the HKZ alpha jacket in 2020. The jacket was transported to the HKZ location on Sleipnir’s deck after being picked up in Amoy Fjord, Stavanger, Norway on June, 22. After that, the vessel and jacket sailed to the HKZ location around 22km off the coast of Scheveningen, the Netherlands.
Sleipnir is the world’s most sustainable SSCV, and during the project, the vessel performed the full installation operations while running on emission-reducing LNG fuel. Using LNG, Sleipnir reduces CO2 emissions by 25%, reduces NOx emissions by 92%, reduces SOx emissions by 99%, and Particulate Matters by around 99% compared to traditional Marine Gas Oil crane vessels.
