Norway-based technology certification body DNV GL has issued a ‘statement of feasibility’ for French Alstom’s Oceade 18 tidal turbine.

Alstom has received orders to deliver four of the turbines, each with a power generation capacity of 1.4MW, at one of the world’s first tidal stream arrays in the Raz Blanchard, France.

The firm used DNV-OSS-312 for the certification process, which involves an initial full risk assessment of the turbine, assenting to actions aiming for risk mitigation in case of failure.

DNV GL will co-ordinate with the turbine manufacturer to carry out a review and approval of the turbine design documents before proceeding with the fabrication stage. This will include evaluation of the manufacturing quality and equipment testing, as well as surveillance of the installation and commissioning of the model.

"Alstom is taking a responsible approach to managing risk and putting in place the foundation for a successful project."

Final Prototype Certification of the turbine will be issued after successful completion of the actions agreed upon in the statement of seasibility stage.

DNV GL business development 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."

Last year, Alstom, along with GDF SUEZ, was selected by France to supply equipment for a tidal energy pilot farm at Raz Blanchard, west of the Cotentin peninsula (Manche).

Expected to be operational in 2017, the sea-based project is designed to generate 5.6MW of wave energy, which is enough to meet the needs of 5,000 people.
