Heerema Marine Contractors’ LNG-fueled semi-submersible crane vessel Sleipnir has completed the installation of the second jacket of TenneT’s offshore transformer platforms for the Hollandse Kust Zuid (HKZ) wind farm in the North Sea.

Located 22 kilometres off the Netherlands coast, the 2,852-tonne heavyweight is the foundation on which the transformer platform will be placed, before the connection of the wind farm, which will be ready for use in 2022.

At 50 metres long, 34 metres wide and 44 metres high, the jacket is anchored to the seabed by six piles, each weighing 162.5 tonnes. These form the foundations for the second of the two transformer stations that Petrofac is delivering for TenneT as part of the HKZ project.

The transformer platforms will have a capacity of 700 MW each. The first jacket for the wind farm was installed in September last year.

Sleipnir, the largest heavy lift vessel in HMC’s fleet, performed these operations while running on LNG fuel.

Marco Kuijpers, TenneT’s Director Offshore Projects said: “The past year has been characterised by uncertainty and challenges due to the COVID pandemic. Not only for TenneT, but also for our contractors and suppliers. Nevertheless, together we succeeded in achieving this performance. We can be proud of that.”
