On behalf of TenneT, the jacket for the Hollandse Kust (west Beta) transformer platform has been placed on the seabed off the North Holland coast.The ready-made topside will be installed next year. The steel structure measures 49 metres high, weighs more than 2,100 tonnes, and is anchored at the four corner points using piles driven more than 50 metres into the seabed. These piles are placed in large tubes of 10 metres that are welded to the feet of the chassis. By filling the space between the piles and the pipes with cement (grout), a connection is created that ensures the platform can withstand even the heaviest storms on the North Sea. TenneT's socket is intended for the wind farm that RWE/OranjeWind will build at sea in the coming years.
