Vattenfall has selected Siemens Gamesa’s 10 MW offshore wind power turbine for the Hollandse Kust (Zuid) 1&2 offshore wind farms. Should the Swedish developer also be awarded the Hollandse Kust (Zuid) 3&4 tender then it will also deploy this turbine type. The complete Hollandse Kust (Zuid) project would then involve 152 wind turbines.
Siemens Gamesa’s latest generation offshore wind turbine, the SG 10.0-193 DD, has 94 metre-blades and a rotor diameter of 194 m. According to the wind turbine manufacturer the offshore turbine could increase efficiency by 30%. With a capacity of 10 MW, the new turbines will enable this wind farm to generate enough electricity to supply 1-1.5 million households each year
Gunnar Groebler states: “Due to the increased capacity, we require fewer turbines to be placed at Hollandse Kust Zuid which clearly reduces the environmental impact of thiswind farm compared to earlier ones. Larger turbines and greater availability also lead to major advantages in terms of electricity generation, which is particularly important in a subsidy free environment. Having fewer turbines to install also means lower costs and fewer risks during the installation process”.
In September 2018, Vattenfall received an irrevocable licence to build Hollandse Kust Zuid 1&2, the first non-subsidised wind farm in the Netherlands. The initial preparations for this wind farm are now under way and various studies have started at the North Sea wind farm site. The wind farm is scheduled for completion in 2023.
For Hollandse Kust (Zuid) 3&4, Vattenfall has also secured the contracts for the cable production, the foundations and installation vessels. Subject to the tender being awarded to Vattenfall, the foundations will be provided by Sif Group B.V and the cables by Prysmian. The installation work for the foundations and cables will be performed by Seaway Heavy Lift. The wind turbines will be installed by Swire Blue Ocean. Source: Vattenfall
