Jan De Nul Group and LS Cable to connect Dutch duo
TenneT has awarded a consortium of Jan De Nul Group and LS Cable &
System contracts for the supply and installation of high voltage cables
for the grid connection for the Hollandse
wind farms. Jan De Nul Group will take care of the transportation, laying
and protection of the cables that will be designed and manufactured by
LS Cable & System. Offshore execution will take place in 2022-23.
The Hollandse Kust Noord and Hollandse Kust West Alpha export cable systems
will consist of two 220 kV AC cable systems each. These four cable systems
will cover a total length of 210 km, connecting the wind farms to the onshore
Dutch power grid near Beverwijk, just north of the port of IJmuiden. When
operational, these wind farms will generate up to 1,400 MW, enough green
electricity to meet the annual needs of one million households.
Dick Lagerweij, Project Director HKN/HKWa TenneT Offshore, said: “Since
Q3 2018 TenneT has prepared the project documents for offshore cable installation.
Five bidders were qualified to submit their proposals and early 2020 we
concluded that the consortium was best placed to win this contract. We
are aiming for completion of the project as a whole by 2023, and the offshore
cable installation including beach works and termination to the platforms
is a vital part of the project. We are much looking forward to a positive
Philippe Hutse, Offshore Director at Jan De Nul Group, said: “We are
proud to have been selected by TenneT to take on this project together
with our partner LS Cable & System. Our versatile offshore installation
vessels are ideally suited to bring this project to a successful conclusion.
Thanks to its very large carrying capacity, our Cable Lay Vessel Isaac
Newton will load the cables in Korea and transport them to the Netherlands
for installation with a minimum number of offshore joints. Our Multi-Purpose
Support Vessel Adhémar de Saint-Venant will execute the post-lay trenching
works and the rock protection works at the subsea crossing locations.”
