Norway-based energy giant Equinor has a new floating wind turbine foundation design and wants to launch it in a Scottish gigawatt (GW) offshore wind farm project.
If Equinor succeeds in its bid for ScotWind, which is an offshore wind program that will lease areas of the seabed around Scotland for the development of wind farms up to 10 GW, then it will use its new wind turbine foundation design there. floating.
Its new design is called the Wind Semi. Equinor says it is suitable for rough waters, such as those off the Scottish coast, and can “maximize opportunities for the Scottish supply chain”. Equinor says the following about the Wind Semi:
- Increased reliability: By introducing a passive ballast system, the Wind Semi has a simple substructure design, reducing the risk of system failure and the amount of maintenance required.
- Simpler and more robust design: A flat plate design free of struts, lift plates and complicated knots that can fatigue cracking
- Supply chain flexibility: With a draft of less than 10 m, the integration of the Wind Semi turbine can be assembled in most industrialized ports. The Wind Semi’s simpler flat plate design allows the substructure to be built into blocks that can be manufactured locally and / or shipped from other locations.
Sonja C. Indrebø, Vice President of Equinor Floating Offshore Wind, said:
We are poised to develop the next generation of large scale commercial floating offshore wind in Scotland. Leveraging our 20 years of experience and innovations in floating offshore wind, we plan to develop GW-sized floating projects in a single phase. The implementation of large-scale projects will accelerate Scotland’s energy transition to net zero.
At 1 GW, this project would be over 30 times the size of Hywind Scotland, the UK and Equinor’s first floating project, and would have the potential not only to position Scotland as a leader in deepwater technology , but also to create opportunities for existing suppliers and new entrants. to the offshore wind sector.
Hywind Scotland was the first floating offshore wind farm from Equinor and the UK, with a capacity of 30 MW. It was uploaded in 2017.
