Blue Gem Wind, the joint venture between TotalEnergies and Simply Blue Energy, has begun geotechnical investigations on the Angle Peninsula.

The work, which began in late May, is being led by Tetra Tech and is scheduled to last for up to six weeks. The scope covers excavating trail pits and borehole drilling to create small diameter holes to obtain samples of soil and rock.  

Ben Huskinson, Consenting Manager at Blue Gem Wind, said: “These works involve examining soils and collecting samples of rock along the proposed onshore cable route for the Erebus floating wind farm. We will be carrying out the investigations from Pembroke Power Station across to West Angle Bay.  Each location has been carefully selected to provide good representative samples, and avoid sensitive ecological and archaeological features.”

“Katy Woodhouse, Geo-Environmental Engineer at Tetra Tech, added: “We are delighted that our Cardiff based geo-environmental team have been chosen to work with Blue Gem Wind on this exciting low carbon project. ”

Blue Gem Wind is focussed on developing floating wind in the Celtic Sea, using a "stepping stone" approach. As its first proposed project,
Erebus is expected to provide enough green energy for approximately 90,000 homes per year. The project is to have a 96 MW capacity and will be installed in an area with a water depth of 70 metres. An application has been submitted to the Crown Estate.

The parties are planning to develop the project using Principle Power’s WindFloat technology. WindFloat is a semi-submersible floating foundation with "water entrapment plates" fitted onto the bottom of the three pillars and a static and dynamic ballast system to enable stability.
