World’s Largest Crane Vessel ‘Sleipnir’ is Warming Up for Mobilization to her First Job

Netherlands based world leading marine contractor Heerema’s semi submersible crane vessel ‘Sleipnir’ is undergoing sea trials for Hollandse Kust (zuid) Alpha project

On 14 May 2019, Heerema Marine Contractors (“HMC” or “Company”) was awarded the Petrofac contract for TenneT’s Hollandse Kust Zuid (HKZ) Alpha project, one of the largest offshore wind farm zones being developed in the North Sea in front of the Dutch coast.

The award entails the transport and installation of the HKZ Alpha HVAC platform. This platform is a high-voltage substation, an essential component of offshore wind farms that run electricity to the mainland, in this case the Maasvlakte. The jacket (2,800 metric tonnes) for the HKZ Alpha substation will be installed in the second quarter of 2020 and the topside (3,800 metric tonnes) in the fourth quarter of 2020, HMC said.

The installation will be performed by one of Heerema’s newest vessel, Sleipnir. Sleipnir is a Semi-Submersible Crane Vessel and can also operate in shallow waters. During the tender preparations Heerema used its Simulation Center to successfully explore the feasibility of the jacket and topside installation by Sleipnir in this shallow water location close to shore.

Hollandse Kust (zuid) Alpha will go into service in 2021.
