Seaway 7 Install Last Foundation on Hollandse Kust Zuid
“Last pile is in. Done and dusted. Thanks to all involved!” Victor Donchenko, Captain of Seaway 7’s Seaway Strashnov.
On the 4th September, a new milestone was reached in the construction of Vattenfall’s wind farm Hollandse Kust Zuid when the last of 140 monopiles was piled into the Dutch sector of the North Sea.
Vattenfall’s Foundation Installation Manager, Mary Carol Anderson, reflected on this milestone: “A big achievement by the project team, our contractors – Seaway 7 and Sif – and all other parties involved. Going from installing 34 foundations in the 2021 summer campaign, to installing 106 foundations in 2022, is a huge testament to the team!”
The 8m diameter foundations manufactured by Sif have lengths between 62m and 75m, and weigh between 735t and 955t.
There are two jack up installation vessels currently working on the wind farm project. Cadeler’s Wind Osprey continues installing the Siemens Gamesa 11MW turbines at a tip height of 251m, and the 97m long recyclable blades. Four sets of turbines and blades are loaded on the Wind Osprey for each voyage from the quay side at Sif on Maasvlakte 2 in the Port of Rotterdam to the wind farm location.
On completion, due early in October 2023, the wind farm will be rated at 1.52GW.
