Iemants (part of Smulders) has awarded Heerema Fabrication Group (HFG) with a contract for the construction of the Hollandse Kust (noord) offshore transformer substation jacket. The jacket is planned to be ready in September this year.

TenneT, as the offshore grid operator in the Dutch part of the North Sea, is responsible for the offshore connection. Following a European tender procedure, In 2020, TenneT selected the joint venture ENGIE Fabricom – Iemants contract for the engineering, procurement, construction, offshore installation, connection and testing of the offshore transformer station for the Hollandse Kust (noord) wind farm zone. In September 2020, the first steel cutting for the topside took place.

HFG will now build the jacket for the station. The jacket will be 44 meters high and consists of 1,600 tons of steel. Construction will occur at the HFG Vlissingen yard, with fabrication scheduled to begin in January 2021 and completion planned for September 2021.

Standardised 700 MW offshore platforms
The station is the fifth to be built using the standardised 700 MW design that TenneT introduced. The first high-voltage connections for the wind farms near Borssele is now operational,and will be followed by the connections for Hollandse Kust (zuid) in 2022.
