U.S.-based Columbia Power Technologies was recently awarded a Statement of Feasibility by international certification body DNV GL for its StingRAY wave energy converter.
The statement, issued by DNV GL during the recent International Conference on Ocean Engineering (ICOE) conference in Edinburgh, Scotland, is an important milestone for the StingRAY device as Columbia Power tales the next steps toward prototype certification.
"Issuing the DNV GL Statement of Feasibility is an important step demonstrating that Columbia Power is taking a robust and transparent approach to managing risk," said Benson Waldron, Head of Section, Wave and Tidal Certification for DNV GL. "We are pleased to be working with and supporting Columbia Power and look forward to continuing the journey to prototype certification with a long-term objective of full commercialization."
The Statement of Feasibility recognizes the StingRAY converter as having satisfied the issuing organization's DNV-OSS-312 specifications for wave and tidal devices. The certification also recognizes Columbia Power's willingness to openly work with interested stakeholders -- including the U.S. Navy, U.S. Department of Energy and potential customers -- as work on the device progresses.
"We are extremely pleased with the achievement of this important milestone," Columbia Power CEO Reenst Lesemann said. "It points to both the experience and expertise of our product development and delivery team and to our technical leadership within the industry. Our team found the certification process rigorous, but extremely beneficial towards ensuring that we have a firm understanding of the risk management requirements and processes."
DNV GL will continue working with Columbia Power to review and approve design documents before the StingRAY device enters the fabrication stage. The watchdog group said this includes manufacturing quality, equipment testing, and surveillance of the installation and commissioning of a unit at the Navy's wave energy test center in Hawaii.
StingRAY units are intended to be deployed in arrays at depths of more than 60 meters, with these clusters located up to three kilometers from shore.
