Subsea 7 has announced the award of a sizeable contract for the Kaskasi offshore wind farm project located about 35km north-west of Heligoland in the German sector of the North Sea.
The contracted work scope includes the transport and installation of the offshore substation foundation, 38 wind turbine monopile foundations and 52km of inner array grid cables in water depths of between 18 and 25 metres. The offshore installation is scheduled to begin sometime in 2021 and 2022 using Seaway 7’s heavy lift, cable lay and support vessels.
When completed, the Kaskasi offshore wind farm will have an installed capacity of 342 megawatts.
Steph McNeill, executive vice president of Renewables at Subsea 7, said: “We are pleased to continue our partnership with innogy on the Kaskasi II project, after having collaborated on other projects such as Nordsee One and Triton Knoll.
“It will benefit from being managed as an integrated foundation and cable installation project leveraging the available capabilities within Seaway 7, and will use an innovative vibratory hammer installation approach to minimize the noise levels during offshore installation of the monopiles.”
