Subsea 7 has announced the award of a sizeable contract by innogy Kaskasi GmbH for the Kaskasi offshore wind farm project, located approximately 35 kilometres 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 52 km of inner array grid cables in water depths of between 18 and 25 metres. Offshore installation is scheduled for execution 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, EVP Renewables, says, “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 minimise the noise levels during offshore installation of the monopiles.”
Note: Subsea 7 defines a sizeable contract as being between USD 50 million and USD 150 million.
