LEIDEN, the Netherlands Heeremas semisubmersible crane vessel Sleipnir has transported and installed the 2,852-metric ton (3,144-ton) jacket for the Hollandse Kust Zuid (HKZ) transformer platform in the Dutch North Sea.

The six-legged jacket was transported to the HKZ location on the Sleipnirs deck after being picked up in Amoy Fjord, Stavanger, Norway on June 22. Then the vessel and 50-m (164-ft) long jacket sailed to the HKZ location about 22 km (14 mi) offshore Scheveningen, the Netherlands.

This is the Sleipnirs second on the HKZ project. The vessel installed the HKZ alpha jacket in 2020.

The Sleipnir performed the full installation operations while running on emission-reducing LNG fuel. By using LNG, the Sleipnir reduces CO2 emissions by 25%, NOx emissions by 92%, SOx emissions by 99%, and Particulate Matters by around 99% compared to traditional Marine Gas Oil crane vessels, according to Heerema.
