Both Geosea and Van Oord have been awarded contracts for Ørsted’s Borssele 1 and 2 offshore wind farms off the coast of the Netherlands.
Geosea has been awarded the contract for the transportation and installation of 94 foundations, while Van Oord has announced it has been awarded the contract for the transportation, installation and burial of the 94 inter array cables.
Borssele 1 and 2 are located 23km from the Dutch coast and will have a total capacity of 752 MW when completed.
Van Oord will deploy its dedicated cable-laying vessel Nexus for the installation of the cables and trencher Dig-It will bury 167km of cables to the required depth of 2m.

Under Geosea’s contract, the firm will be responsible for the full scope of the Borssele 1 and 2 foundation installation and scour supply and installation.
Geosea will transport and install the wind turbine foundation structures including the supply, transport and installation of scour protection on each location.
The monopile foundations will have pre-installed scour protection, an anode cage and a bolted transition piece. Water depths range from 14m to 36m.
Under a separate contract A2sea, part of Geosea, will provide installation vessel capacity to transport and install the Siemens Gamesa 8MW turbines at the Borssele 1 and 2 wind farm.
Geosea business unit manager offshore renewables Jan Klaassen said: “We are pleased that Ørsted has selected Geosea for the largest offshore wind farm project in the Netherlands.
“The contract award demonstrates our leading position as a provider of state-of-the-art, integrated solutions for the offshore wind industry.
“We look forward to working with Ørsted and to leverage our joint expertise in order to successfully deliver this project.”
Monopile and turbine installation is scheduled in 2020.
In April MHI Vestas Offshore Wind appointed the Two Towers Consortium, formed by Van Oord, Investri Offshore and Green Giraffe, to deliver Borssele Wind Farm scheme.
