The initially monopile as well as change item have actually been set up at the Dogger Bank Wind Farm in the U.K. North Sea, noting a crucial turning point for the building of the globe’s biggest overseas wind ranch.
The structures, made by Wood Thilsted, depend on 72m in size, consider on ordinary 1057 tonnes as well as consist of the globe’s biggest 8m overseas wind flange. The layout consists of the globe’s initial split-level change item for secure installment as well as procedure, with installment functions being led by Seaway 7 with assistance from DEME.
Paul Cooley, supervisor of overseas wind at SSE Renewables, among the joint endeavor (JV) firms associated with Dogger Bank, claimed, “This is a really important milestone for the project as it marks the commencement of our campaign to install 277 turbine foundations across the three phases of what will be the world’s largest offshore wind farm.”
Dogger Bank Wind Farm, a JV in between SSE Renewables (40%), Equinor (40%) as well as Eni Plenitude (20%), is comprised of 3 overseas wind ranch websites greater than 130km off the North East shore ofEngland When functional the wind ranch will certainly produce 3.6 GW of power.
SSE Renewables is lead driver for the growth as well as building of Dogger Bank, while Equinor will certainly be lead driver of the wind ranch on conclusion for its anticipated functional life of around 35 years.
“As lead operator during the construction phase of Dogger Bank Wind Farm, we’re working with our development and supply chain partners to install some of the world’s largest turbine foundations on this world-class project,” Cooley claimed.
“During this campaign we’re using foundations that are U.K.-designed and with components made from U.K.-manufactured steel, all of which are helping to support U.K. jobs and a fair and just transition to net zero.”
Steel made by Tata Steel in Wales as well as refined in Corby as well as Hartlepool is being made use of in the sustaining parts of the change items, while South Tyneside- based Metec as well as Rochdale- based Granada Material Handling have actually likewise won agreements with Smulders to sustain the job.
The structures have actually been maximized to take on difficult wave lots in the Dogger Bank location of the North Sea, with installment in water midsts of approximately 32m as well as at a range of 130km from coast as well as supply a strong as well as secure base for the range of the GE Renewable Energy’s Haliade- X generators, which are arranged to be set up onto each of the wind turbine structures beginning with Spring 2023. Each wind turbine has a power outcome of approximately 14MW.
lastair Muir Wood, CHIEF EXECUTIVE OFFICER of Wood Thilsted, claimed, “Wood Thilsted is proud to be a part of making Dogger Bank Wind Farm a success. Our team faced challenges including working with the largest turbine at the time, an innovative dynamic positioning installation vessel, and some very significant wave loads.
“What made success possible was the collaborative working relationship shared with the Dogger Bank team and the other key stakeholders. This project is a model of success for current and future projects.”

Over the three-year installment program for the 3 stages of Dogger Bank, an overall of 277 monopiles as well as change items will certainly be filled onto installment vessels in Rotterdam in advance of transfer bent on the overseas wind ranch website. Using vibrant placing innovation, the vessels will certainly determine the installment website in the seabed whereupon a monopile coming up to 72m will certainly be overthrown as well as moved to a stack gripper, prior to being reduced right into the seabed.
A hammer will certainly be made use of to drive the monopile to the layout deepness in the seabed prior to a support system lines up the installment of the record-breaking 8-meter flanges, which serve as a link for the change item which is after that set up onto the monopile. The structures need 152 gigantic M80 screws to protect them prior to a cover is put onto the top of the change item to leave it watertight.
Seaway 7 was granted the rate one agreement for structure installment on all 3 stages of Dogger Bank Wind Farm, with sub-contractor DEME– likewise the job’s inter-array cable television installer– releasing its Innovation overseas installment vessel for the initial structures on Dogger Bank A. Later, the Seaway Strashnov will certainly release on Dogger Bank A to proceed the structure installment.
Lucien Romagnoli, renewables organization device supervisor at DEME Offshore, claimed, “These unique foundations are huge but also, they are technically complex. This is an important moment for the offshore wind industry and the energy transition.”
In November 2020, the consortium Sif as well as Smulders was granted the agreement for the manufacture of all 190 monopiles as well as change items for the Dogger Bank An and also B stages of the wind ranch, with an agreement for Dogger Bank C’s continuing to be 87 monopiles as well as change items granted to the consortium in 2021.
