Jumbo Offshore has deployed the vessel Fairplayer and crew to transport and install secondary steel for 106 pre-installed monopiles at the Hollandse Kust Zuid offshore wind farm, currently being built in the North Sea.

The Hollandse Kust Zuid (HKZ) Wind Farms will be operated by the Dutch energy company Vattenfall, in collaboration with BASE and the German multinational, Allianz. HKZ 1&2 and HKZ 3 & 4 are being built by Heerema. Seaway 7 will build 140 foundations and a 66 kV inter-array cable system, and Heerema will  install secondary steel for 106 of the 140 foundations this summer.  

Installation of the secondary steel consists of a Boat Landing System, an External Working Platform, and an Airtight Platform, and a versatile Offshore Construction Vessel such as the Fairplayer, as well as a skilled crew. 

Once completed, Hollandse Kust Zuid Wind Farm will have a renewable electricity output equivalent to the annual consumption of over two million Dutch households, and will also be the largest subsidy-free wind farm at sea.
