Vattenfall plans to start the first offshore construction activities on the 1.5 GW Hollandse Kust Zuid (HKZ) wind farm in the Dutch North Sea in June.
This is when the first ships will sail out to deliver rocks for scour protection to the wind turbine locations. Rocks will be placed to protect the monopiles against waves and currents that can cause erosion of the soil around fixed structures in the seabed.
From July onwards, the first of the 140 monopile foundations without the transition pieces will be installed at the site.
”Our foundation installation vessel the ‘Seaway Strashnov’ – a 183 m long and 47 m wide heavy lift vessel – will load three complete sets of monopiles and secondary steel components from the quay side of our foundation manufacturer, situated on the Maasvlakte in Rotterdam,” Sven Mey, Construction Manager, said.
”The vessel will sail to the offshore site to install the monopiles and secondary steel parts, such as the internal airtight platform, external work platform and the boat landing.”
