Bladt Industries has confirmed two contracts with Innogy for foundations and the offshore substation for the 342MW Kaskasi offshore wind farm in the German North Sea.
The Danish fabricator will deliver 39 monopiles and 38 transition pieces and one TP special designed for the offshore substation, which Bladt Industries will also supply under an EPCI contract.
Work will start on the foundations in the third quarter of 2020, with the final monopile scheduled to leave the Aalborg site (pictured) in Denmark by third quarter of 2021.
Bladt Industries chief executive Klaus Steen Mortensen said: “It is clearly an advantage for the project, that we have been able to provide guidance and inputs to ensure the most optimised fabrication design.
“This early involvement has been a productive process for both parties and I am convinced that it will pay off in the end.”
Bladt said the substation deal will be executed in close cooperation with its long-term partners Semco Maritime and ISC Engineering.
ISC Engineering will carry out the substation design, while Semco Maritime will design and carry out the electrical installations.
Installation is scheduled for the first half of 2022.
The platform will be the 22nd substation that Bladt Industries will have fabricated and the fourth to be delivered as a turnkey project to German waters.
Bladt chief sales officer Nils Overgaard said: “I am delighted that we have signed the contracts with our partner, Innogy for the delivery of both the foundations and the offshore substation.
“I am certain that the mutual proven experience from previous projects will be a cornerstone for our teams, when we enter into mobilisation and this will pave the way for a significant reduced risk mitigation in the execution phase in order to meet the important milestones.”
Meanwhile, Subsea 7 also confirmed a contract with Innogy for the transport and installation of the offshore substation foundation, 38 monopiles and 52km of array 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, the company said.
Subsea 7 executive vice president of renewables Steph McNeill said: “We are pleased to continue our partnership with Innogy on the Kaskasi 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.”
