Smulders progresses Hollandse Kust West Alpha jacket

At the Heerema yard in Vlissingen, the jacket foundation for TenneT’s 700 MW Hollandse Kust West (HKW) Alpha offshore transformer station was recently upended.

Smulders expects the cable deck to be installed in the next few weeks. The jacket 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 Netherlands.

TenneT’s Hollandse Kust West Alpha offshore wind farm will have an offshore substation built by Smulders and EQUANS. The offshore transformer substation will be designed, procured, built, installed offshore, connected, and tested as part of the contract.

Along the Dutch coast, in the North Sea, will be three new offshore platforms: the Hollandse Kust north, west Alpha, and west Beta. TenneT will build and operate three 700MW platforms in the Netherlands, the company’s fifth, sixth, and seventh large-scale grid connections for offshore wind energy.

TenneT’s transformer substations are an essential part of the offshore grid. Standardization of these 700MW platforms will substantially reduce the costs of development, construction and maintenance. In the third quarter of 2023, Hollandse Kust West Alpha is expected to be fully offshore commissioned.
