Sif Group has completed the first two of the 70 monopiles to be manufactured for CrossWind’s 759 MW Hollandse Kust Noord offshore wind farm in the Netherlands.
With a combined weight of 64,356 tonnes, the 70 monopiles are designed in such a manner that they do not require transition pieces. The design is said to allow faster installation and cost reductions.
The TP-less monopiles, which are being manufactured at Sif’s Maasvlakte facility in Rotterdam, will support Siemens Gamesa’s SG 11,0-200 DD 11 MW wind turbines installed at the site some 18.5 kilometres off the coast of Egmond aan Zee.
Sif secured a contract with Van Oord , the Balance of Plant contractor for the project, for the fabrication and supply of monopiles in 2020.
The Hollande Kust Noord offshore wind project will be built and operated by the CrossWind consortium between Shell and Eneco, which won the tender in July 2020, without government subsidies.
The offshore construction is in full swing with the substation topside installed a few days ago.
The consortium plans to have the offshore wind farm operational in 2023, from when it will be generating at least 3.3 TWh per year.
When it comes to Sif, the company is also providing the monopiles for the 1.5 GW Hollandse Kust Zuid offshore wind project.
