DNV GL is supporting Alstom through the process of achieving Prototype Certification of its innovative tidal turbine Oceade 18 – 1.4 MW.  Alstom will supply four of the tidal turbines to one of the world’s first tidal stream arrays in the Raz Blanchard, in France. In the first milestone in the process, DNV GL has issued a ‘Statement of Feasibility’.
The turbine design is said to be at the leading edge of advanced tidal technology, being an evolution of the 500 kW and 1 MW demonstrators tested at the European Marine Energy Centre, Scotland. Both the 500 kW and 1 MW demonstrators have completed DNV GL Design Assessment.  DNV GL is using the industry recognised DNV-OSS-312 to certify the Oceade unit, 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.
Claudio Bittencourt, Business Development director, DNV GL, commented: "Issuing the DNV GL Statement of Feasibility is an important step in demonstrating that Alstom is taking a responsible approach to managing risk and putting in place the foundation for a successful project."
