DONG and Con4Mare enter huge deal
DONG Energy has chosen the Hamburg-based Con4Mare as a supplier of transport and installation of transitional pieces and monopile foundations at the 1.2 GW Hornsea Project ONE offshore wind farm in the Danish part of the North Sea.
Royal Boskalis Westminister has won a contract for the transport and installation of part of the foundations with its new offshore transport and installation vessel. The company will rebuild an existing F-Class heavy-lift transport vessel. Boskalis has not revealed exactly how many of the wind farms’ 174 foundations this contract covers.
Bladt is responsible for building 96 transitional pieces for the wind farm. 56 will be produced at the Offshore Structures Britain plant in Haverton Hill near Billingham, Teesside, while the remaining 40 are manufactured at Bladt's facilities in Aalborg.
Steelwind will produce another 20 transition pieces. EEW Special Pipe Constructions GmbH (EEW SPC) will produce all the monopile foundations for the offshore wind farm. The installation of foundations and internal cables in the wind farm is currently expected to start only in 2018.
The Hornsea Project ONE will consist of 174 Siemens 7 MW turbines and, when fully operational by 2020, will become the world's largest wind farm.
