A consortium of Belgian companies ENGIE Fabricom and Iemants has been awarded the contract for the supply of the offshore platform for the Hollandse Kust (noord) wind farm. Grid operator TenneT launced a tender earlier this year. The contract also includes an option for the Hollandse Kust (west alpha) and Hollandse Kust (west beta) projects.

The Hollandse Kust (noord) wind farm zone allows for the construction of a wind farm with a total installed capacity between 693 MW and 760 MW. The scope of the contract includes design, engineering, production, delivery, transport and installation of the topside and jacket.

The topside measures 45 m (l) x 21 m (w) x 30 m (h) and will weigh approximately 3,000 tons. The weight of the jacket is around 1,650 tons. The platform is to carry high-voltage switching and transformation equipment 220kV as well as auxiliary facilities. Here, the power (66 kV) from the future wind farm will be transformed to 220 kV. Each platform is connected to the onshore grid by two three core 220 kV AC sea cable circuits and, if applicable, by single core 220 kV AC land cables.

The platform follows the standardised 700 MW offshore connection concept introduced by TenneT. The Dutch grid operator is building 5 identical platforms with a combined capacity of 3,500 MW as part of the 2023 programme. The platforms will be unmanned. All control is normally carried out from the onshore control center.
