October 2019

In October the Olympic Challenger was contracted to Sabella SAS for installation of a horizontal axis tidal turbine 2km South-East off the coast of Ushant Island, France.

The tidal turbine has a rated capacity of 1MW and the nacelle is moored to the seabed using a gravity base structure. Power is brought to shore via a jumper cable. The turbine was deployed by the vessel crane and guided into position by the WROV’s onboard. The ROVs also performed pre-/post survey, preparatory work and electrical hook-up of the turbine. Dry weight of the turbine is 107 tons and requires a capable subsea construction vessel for such a complex lifting operation.
