The jacket foundation for TenneT’s 700MW Hollandse Kust West (HKW) Alpha offshore transformer station was recently upended at the Heerema yard, in Vlissingen.
Assembly can now continue with the installation of the cable deck in a few weeks, said Smulders.
The jacket, weighing more than 2300 tonnes and standing 49 metres in height, will be ready this summer.
The structure is part of the second substation for the Hollandse Kust West Alpha project.
The substations will be installed off the coast of Egmond aan Zee in the north of the Netherlands.
The Hollandse Kust (noord), (west Alpha) and (west Beta) offshore platforms will be located in the North Sea along the Dutch coast.
These three 700MW platforms will be the fifth, sixth and seventh large-scale grid connections for offshore wind energy in the Netherlands to be constructed and operated by TenneT.
Hollandse Kust West Alpha is scheduled to be fully offshore commissioned in the third quarter of 2023.
