DEME Offshore has won a contract for the transport and installation of 165 foundations at Ørsted’s Hornsea Two offshore wind farm in the UK. The company will also transport and install the turbines at the wind farm.

The 1,4 GW Hornsea Two wind farm is located approximately 89 km off the Yorkshire coast and will meet the electricity needs of over 1.3 million homes per year. The wind farm borders the northern and western edge of the Hornsea One wind farm, where DEME Offshore was already involved in the foundations, turbines and export cable works.

Orion to Install the Monopile Foundations

DEME Offshore will transport and install the 165 monopile foundations and carry out scour protection. The monopiles and transition pieces will be installed by the company’s new DP3 offshore installation vessel Orion, entering the fleet by the end of the year. The new flagship features an unrivalled combination of exceptionally high transport and load capacity, as well as a crane with a 5000 t lifting capacity.

Turbine Installation

The company will also provide installation vessel capacity to transport and install 165 Siemens Gamesa 8.4 MW turbines at the wind farm. Turbine installation will be carried out with offshore installation vessels Sea Challenger and Sea Installer. Installation should be completed in early 2022.

The total contract value is over EUR 200 million.
