DNV GL, one of the world’s largest resources of independent energy experts and certification body, has issued a Statement of Feasibility for Alstom’s Oceade tidal turbine.
DNV is supporting Alstom, through the process of achieving Prototype Certification of the Oceade 18 – 1.4 MW, with the Statement of Feasibility seen as the first milestone in the process.
Alstom has been selected to supply four of the tidal turbines to one of the world’s first tidal stream arrays in the Raz Blanchard, France. The turbine design is an evolution of the 500kW and 1MW demonstrators tested at the European Marine Energy Centre, Scotland. Both the 500kW and 1MW demonstrators completed DNV GL Design Assessment. DNV GL is using the industry recognised DNV-OSS-312 to certify the Oceade 18 – 1.4 MW tidal turbine, with the first stage in the process involving a full risk assessment of the turbine and agreeing actions to mitigate the risk of failure.
DNV GL will now work with Alstom to review and approve design documents before heading towards the fabrication stage, including manufacturing quality and equipment testing and surveillance 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.
"The Statement of Feasibility is the first milestone in delivering a high-performing safe & reliable tidal turbine for our customers," commented Rob Stevenson, Vice-President, Ocean Energy, Alstom. "We look forward to continuing our journey with DNV GL to gain full Certification for the Oceade™ 18 – 1.4MW."
