The final monopile for CrossWind’s 759MW Hollandse Kust Noord wind farm was successfully installed by Van Oord this week, bringing the total to 70.
The offshore wind farm is located 18.5 kilometres off the coast of the Netherlands, near the seaside resort of Egmond aan Zee.
The first monopile was installed less than four months ago, on 17 October 2022.
Roeland Ris, Project Director Van Oord, said: “After an extensive period of preparations, it’s great to now actually see the outlines of the offshore wind farm.
“Thanks to the project team and all partners involved who worked with great efforts and enthusiasm on reaching this important milestone to have all monopiles in place.
“With the supply of secondary steel and inter array cables on target and our offshore installation vessels fully operational, the construction of the Hollandse Kust Noord offshore wind farm is progressing well on schedule.”
Wybren de Vries, Balance of Plant Package Manager at CrossWind, said: “The installation of the monopiles was an immense operation, with the monopiles weighing between 788 tonnes and 960 tonnes each.
“During the installation works CrossWind and Van Oord promoted and maintained an open culture, in which we acted as one team.
“I am convinced that this approach defined a big part of our success in reaching this milestone in a safe and timely manner.”
Van Oord is also involved in the design, engineering, procurement and installation of the inter array cables, as well as the transport and installation of the wind turbines themselves.
Meanwhile Van Oord’s offshore installation vessel MPI Resolution is installing secondary steel to complete the foundations.
The secondary steel sets consist of boat landings, main access platforms (with davit cranes) and internal platforms.
The platforms will be used for maintenance activities once the wind farm is operational.
Van Oord will deploy cable-laying vessel Nexus to install the cables starting in March this year.
