Belgium-based DEME Offshore announced Friday it has been awarded a contract worth approximately €200 million ($223.3 million) for the transportation and installation of 165 foundations and turbines at Ørsted’s Hornsea Two offshore wind farm in the UK.
The 1.40-gigawatt Hornsea Two offshore wind farm is located approximately 89 kilometers 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.
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 flagship DP3 offshore installation vessel Orion, due to enter the fleet by the end of 2019r. According to DEME, the new vessel features a combination of exceptionally high transport and load capacity, as well as a crane with a 5,000 metric tons lifting capacity.
The liquefied natural gas (LNG) powered Orion was launched at the COSCO Qidong shipyard in China in November 2018.
DEME Offshore will also provide installation vessel capacity to transport and install 165 Siemens Gamesa 8.4-megawatt turbines at the wind farm. Turbine installation will be carried out with offshore installation vessels Sea Challenger and Sea Installer, and should be completed in early 2022, the company said.
