Heerema Fabrication Group (HFG) has signed a contract with Iemants, part of Smulders, to construct the Hollandse Kust (noord) offshore transformer substation jacket.
The jacket will be 44 meters high and consists of 1600 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.
TenneT, as the offshore grid operator in the Dutch part of the North Sea, will be responsible for the design, fabrication, installation, and operation of the grid connections that will transport the generated electricity to shore.
Following a European tender procedure, TenneT selected the joint venture ENGIE Fabricom – Iemants to construct the offshore transformer station for the Hollandse Kust (noord) wind farm zone.
HFG’s yard director Richard Spronk said: “We are proud to be collaborating with Smulders on realizing the Hollandse Kust (noord) project, as well as directly contributing to the Dutch energy transition.”
Heerema Fabrication has also been busy with the Greater Changhua pre-piling template for Heerema Marine Contractors.
The offshore platform Hollandse Kust (noord) will be located in the North Sea along the Dutch coast and is due to be operational by 2023.
In 2030, 40% of the electricity demand of the Netherlands will be supplied by the electricity of offshore wind farms.
This 700MW platforms will be the fifth large-scale grid connections for offshore wind energy in the Netherlands, built and operated by TenneT.
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.
TenneT aims to realise approximately 9.6GW of high-voltage connections in the Dutch North Sea by 2030.
