Smulders has announced that both parts of the jacket for TenneT’s Hollandse Kust (West Alpha) substation were upended at the Heerema yard in Vlissingen, the Netherlands.
The first part was upended last week, while the second one was upturned on 11 April.
Assembly work is expected to continue with the installation of the cable deck in a few weeks.
According to Smulders, the jacket structure is 49 metres high, approximately 2,300 tonnes heavy, and will be ready this summer.
It will be installed in 28 metre water depth to support a topside which is currently under construction at the Smulders’ facility in Hoboken, Belgium.
In April last year, Sea and Land Project Engineering (SLPE) was awarded a contract for the detailed design of the Hollandse Kust West Alpha offshore substation jacket and foundations.
Back in 2020, SLPE signed a contract with Iemants, a subsidiary of Smulders, who, in a joint venture with ENGIE, will deliver the offshore substation as a complete turn-key solution for the Dutch transmission operator TenneT.
The transformer substation for Hollandse Kust (west Alpha) is scheduled to be fully offshore commissioned in the third quarter of 2023.
The jacket structure is part of the second substation for the Hollandse Kust Noord & West Alpha project.
The jacket foundation for the Hollandse Kust (Noord) offshore substation was installed off the northern coast of the Netherlands in November 2021.
