Heerema’s SSCV Sleipnir has safely and sustainably transported and installed the six-legged, 2,858t and 46m tall jacket for the Hollandse Kust Zuid (HKZ) transformer station.
Heerema secured the contract for this project with the jacket and topside main contractor, Petrofac.
The transformer station is owned by the Dutch grid provider TenneT and will provide the link to the Dutch onshore grid for the Vattenfall owned Hollandse Kust Zuid offhsore wind farm.
Sleipnir picked up the Alpha Jacket in Vats, Norway, on September and installation was safely and successfully finalized on 9 September.
The vessel was visible during the installation from the beaches at Scheveningen 23 km away on the Dutch coast.
This project is the first job within the wind sector for Sleipnir, Heerema’s largest vessel. Aegir, their fast-moving DP crane vessel is currently working on the TPC Offshore Wind Farm in Taiwan.
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.
So far, Sleipnir has had a busy summer campaigning of decommissioning and installation work and will continue to be busy these coming months.
Heerema’s CEO, Koos-Jan van Brouwershaven noted that ‘Heerema is proud to have worked in Dutch waters to contribute to a more sustainable energy future for The Netherlands, and we are looking forward to delivering more safe and successful projects within the wind sector.
