The jacket for TenneT's Hollandse Kust (North) platform has been installed off the coast of North Holland, the Netherlands. After leaving the port of Vlissingen, the jacket arrived at its destination over 18 kilometers off the coast of Egmond in 20 hours.
After exact positioning at the site, the 2,100-ton steel structure was set on the seabed by the cranes on hoisting vessel Gulliver. The jacket was secured at the four corner points using piles driven into the seabed to approximately 38 meters. The piles are large 10-meter tubes that are welded to the feet of the jacket. By filling the space between the piles and the tubes with grout, the platform will soon be able to withstand even the heaviest storm in the North Sea. Early next year, in anticipation of the placement of the topside, the power cables will be installed that will come ashore on the Heemskerk/Wijk aan Zee beach. The construction of the complete platform will be ready in 2023.
