Foundations needed for Vattenfall’s nearshore pair

Swedish energy company Vattenfall has issued a call for the supply of all required work to manufacture up to 50 monopile foundations for two nearshore wind projects in the Danish North Sea.

The tender is divided into two lots. Lot 1 covers the civil engineering manufacturing of up to 50 transition pieces, up to 25 units for the Vesterhav Syd wind farm, and up to 25 TPs for the Vesterhav Nord.

Lot 2 is for the manufacturing of up to 50 monopile foundations for the two projects.

The contract will run from 31 August 2021 to 31 December 2023.

The tender remains open until 26 August.

Located nine and eight kilometres off the Danish western coast, respectively, Vesterhav Syd and Vesterhav Nord will comprise a total of 41 Siemens Gamesa 8.4 MW turbines with a combined capacity of 344.4 MW.

Vattenfall had initially planned to commission the two wind farms in 2020. However, the developer had to delay the two projects after the Danish Energy Agency had initiated new environmental impact assessment (EIA) processes for the two projects.

Vattenfall also had to cancel several ongoing tenders related to the project, including the ones for the manufacturing and the installation of the monopile foundations.

Vattenfall has since changed the layout of the wind farms, pushing the wind turbines as far offshore as possible.

Back in May, the Danish Energy Agency opened a public consultation on the new EIA reports, with the final permits expected to be issued in September or October.

Vattenfall now plans to commission the two wind farms by 2023.
