Heerema’s Sleipnir completes first wind project
Heerema’s SSCV Sleipnir has safely and sustainably transported and installed the six-legged, 2858 metric ton, and 46-meter 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. While the HKZ windfarm developer is Vattenfall, and the transformer station is owned by the Dutch grid provider TenneT.
This project is Sleipnir, Heerema’s largest vessel, first job within the wind sector. Their fast-moving DP crane vessel Aegir is currently working on the TPC Offshore Wind Farm in Taiwan.
For the HKZ installation, Sleipnir picked up the Alpha Jacket in Vats, Norway, on September 2 before sailing to the HKZ location around 23 km from Scheveningen, The Netherlands. Installation was safely and successfully finalized on September 9, and the vessel was close enough to shore to be visible from the beaches nearby.
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:
‘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."
