International marine and engineering consultancy LOC Group's renewables team is to offer marine warranty surveying (MWS) services for the first offshore windfarms in French territorial waters.
Services will be provided for the 498MW Fécamp, 450MW Courseulles-sur-Mer and 480MW Saint-Nazaire windfarms.
A consortium led by EDF Énergies Nouvelles and Enbridge won the contract to develop the three sites.
LOC Group has been working with the consortium to offer early-stage guidance on the design work and also to ensure the safety of the construction process.
LOC France managing director Hugues Delanoue said: “As the very first turbines to be built in French waters, these are important projects for the development of France’s offshore wind industry.
"The LOC Paris team is also advising and contributing to the review of preliminary submissions for the next round of tenders for the foundations and offshore stations in the French market."
The LOC team is working with EDF Énergies Nouvelles to advise on the transportation, as well as installation of the individual turbines, and ensuring all procedures meet the standards required by the marine warranty surveyor.
As part of its MWS offering, LOC has accounted for the varying environmental conditions and water depth at each site.
Initial drilling indicated different soil conditions, with Saint-Nazaire having a hard seabed, Courseulles-sur-Mer a softer one made up mostly of clay and limestone, and Fécamp’s being chalk-based. Therefore, the 83 turbines at Fécamp will use gravity-based foundations, while the other two locations will use monopole foundations for the turbines.
LOC Renewables Advisory & Energy Technology group director Ahilan said: “France intends to install 6GW worth of windfarms by 2020, and is taking a leading role in developing opportunities in floating offshore wind.
"In this market, the offshore engineers of the LOC Paris team are well-placed to take a lead role in the industry’s development in France."
The company has acted as MWS on more than 1,000 energy infrastructure projects of several types.
