DNV GL has issued a statement of feasibility for Alstom’s Oceade 18 tidal stream turbine, the first stage towards full certification for the 1.4 MW device.

DNV-OSS-312 certification is being utilised to assess the Oceade 18, initially involving a full risk assessment of the tidal turbine and agreeing actions to mitigate the risk of failure.
The Norwegian company will now work with Alstom to review and approve design documents before heading towards the fabrication stage, including manufacturing quality as well as testing of the installation and commissioning.

Final prototype certification of the turbine will follow the successful close out of the actions agreed during the statement of feasibility stage.

Alstom will deploy four Oceade tidal turbines to a tidal stream array in the Raz Blanchard, France.

DNV GL director Claudio Bittencourt said: “Issuing the DNV GL statement of feasibility is an important step demonstrating that Alstom is taking a responsible approach to managing risk and putting in place the foundation for a successful project.”
