Sif Smulders consortium to provide foundations for first two phases of Dogger Bank Wind Farm

17th November 2020 in Press releases, Project news, Supply Chain

Dogger Bank Wind Farm and a joint venture between the Sif Group and Smulders are today (17 November 2020), announcing a contract to provide the wind turbine foundations for the first two phases of the world’s largest offshore windfarm.

Dogger Bank is a joint venture between SSE Renewables and Equinor, with SSE Renewables leading on the construction phase and Equinor leading on the operation for the lifetime of the project of at least 25 years.

As part of the Sif-Smulders consortium, Sif will be responsible for the fabrication and supply of 190 monopiles and primary steel for the transition pieces, as well as for the marshalling of all foundation components. Smulders will be responsible for the supply, fabrication and fit-out of the secondary steel for the transition pieces.

The contract, which is subject to Dogger Bank A and B reaching Financial Close, includes monopile foundations and transition pieces that will be designed by UK-based designers Wood Thilsted. Wood Thilsted were part of the team that pioneered the PISA design methodology for monopolie foundations, using geotechnical engineering through the design process to optimise the final design. Transportation and installation for the foundations will be undertaken by OHT, with installation due to begin summer 2022.

Dogger Bank Wind Farm previously announced a record-breaking contract with GE Renewables to provide 190 of its 13MW Haliade-X turbines for Dogger Bank A and Dogger Bank B.

Dogger Bank Wind Farm Project Director, Steve Wilson, said: “We’re working with the consortium on an innovative approach to manufacturing and installing UK-designed foundations that will support the world’s largest and most powerful wind turbines in operation.

“As the final tier one supplier to be confirmed in the Dogger Bank Wind Farm development, this contract marks a significant milestone for us. In the meantime, we continue to explore opportunities for other UK-based businesses to be part of this developing supply chain.”

Fred van Beers, CEO of Sif Holding, said: “Dogger Bank Wind Farm joint venture partners SSE and Equinor are strong, experienced and reputable customers. Through our facility at MV2 we are well-positioned to serve the Dogger Bank Wind Farm project and we look forward to a continuation of the excellent relationship that dates back many years already. With this biggest award ever to Sif, the projects still in exclusive negotiation and the strong tender pipeline, Sif’s mid-term order pipeline is now looking very robust.”
