Columbia Power Technologies (Corvallis, OR, US) recently received a Statement of Feasibility from DNV GL (Oslo, Norway) for its StingRAY wave energy converter. Columbia Power Technologies has been working with DNV GL to ensure that its StingRAY wave energy device accomplishes the first stage in the prototype certification process.

The StingRAY wave power system, buitl using corrosion-resistant composite materials, is intended to be deployed in water depths of over 60 meters and positioned in arrays formed of multiple devices. These arrays will be located up to 3 kilometers from shore and the device will begin testing when it is deployed to the US Navy’s new wave energy test center in Hawaii.

Columbia Power Technologies have been following the DNV GL certification process outlined in the industry recognized wave and tidal device certification specification ‘DNV-OSS-312.' Issuing a Statement of Feasibility to Columbia Power Technologies successfully completes the first stage of the process and DNV GL will now continue to support them through the next stages towards Prototype Certification.

Achieving the Statement of Feasibility required Columbia Power Technologies and DNV GL to complete a full technology risk assessment and agree actions to mitigate potential risks. This ensured a fully transparent approach to risk, giving stakeholders, such as the US Navy, US DOE and potential customers a clear outlook of the devices’ progress.

DNV GL will continue to work with Columbia Power Technologies to review and approve design documents, before the device enters the fabrication stage. This includes manufacturing quality and equipment testing and surveillance of the installation and commissioning. The final Prototype Certification of the StingRAY technology will follow the successful close out of the actions agreed during the Statement of Feasibility stage.

 “We are extremely pleased with the achievement of this important milestone,” said Reenst Lesemann, Columbia Power Technologies CEO. “It points to both the experience and expertise of our product development & 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. We are also appreciative of the support from the US DOE and US Navy in reaching this advanced stage in our commercialization plan.”
