Two wind measurement buoys have been deployed in the UK Celtic Sea, between Cornwall and Wales, to support floating offshore wind development.

The project is being led by Hayle-based Celtic Sea Power under the £6 million Cornwall FLOW Accelerator program (part-funded by the European Regional Development Fund) which is working to speed up the development of FLOW in the UK and optimise its benefits for the region.

The WINDSEA floating LiDAR (Floating Laser imaging, Detection and Range) systems, provided by French company Akrocean, have been positioned around 60 miles offshore and use laser technology with the aim of measuring wind speeds and direction. Additional meteorological and oceanographic data will also be collected.

The buoys, which are 5.1m high and 2.4m wide, were deployed earlier this week out of Falmouth by specialist marine contractors Keynvor MorLift Ltd. They are expected to remain offshore for one year. The data will build a picture of the wind profile out to sea and form a broad-scale wind resource model.

Neil Farrington, Strategic Offshore Development Manager at Celtic Sea Power explained: “The data from these Floating LiDAR systems will benefit Cornwall, South Wales and the wider South West by feeding into a bank grade regional wind resource model. This model will then be validated by external experts (at Wood Group) to support investment decisions for FLOW sites across the UK Celtic Sea region. It will also help reduce the time it takes to install floating offshore wind farms”.

The Crown Estate has previously announced its intention to run a competitive floating offshore wind leasing round for the Celtic Sea, targeting an overall regional capacity of 4 GW.
