DCNS is poised to install EDF’s second 500kW Arcouest tidal turbine at Paimpol-Bréhat off Brittany by the end of next week.

“We have a good weather window between May 13 and 19 and hope the wave and wind conditions will be good enough for the construction works,” a DCNS spokesperson said.

The French shipyard has hoisted the prototype on a barge in the harbour of Brest, where additional trials will be carried out on Monday and Tuesday.

The machine will be towed through the water to test its mechanical and technical performance.

If the machine is functions well, it will be transported to the offshore site 15km off the coast.

The turbine will be installed on a gravity foundation in about 40m of water.

This second turbine will remain immersed for three years. A first machine was installed earlier this year and will be tested over five years.
