Wave energy converter secures world-first DNV certification

DNV has issued the world’s first Prototype Certificate for a wave energy converter, awarded to Sweden-based CorPower Ocean for its C4 device, in a move the classification society says establishes a new benchmark for the wave energy sector.

The certificate, issued under DNV-SE-0120, the standard for certification of wave energy converters and arrays, followed a seven-year process during which DNV independently reviewed and approved the device’s design, engineering, structural and fatigue analysis, manufacturing, testing, installation and performance in storm conditions with waves up to 18.5m. DNV’s standards already underpin much of the offshore wind industry.

The CorPower C4 is a spherical composite hull, 9m in diameter and 18m tall, weighing around 100tonnes, installed at a water depth of
