While CorPower was developing the product, researchers at Trondheim University invented an innovative phase control technology, which CorPower and NTNU agreed to co-develop. Known as WaveSpring, the patented control system makes the buoy inherently resonant over a broad range of wave periods. It amplifies the motion of and power capture from regular waves, while allowing the system to be naturally ‘de-tuned’ during storm conditions. Tank testing has shown that the buoy can survive waves of up to 32 metres without excessive load on the structure. This significantly improves the system’s ability to survive in harsh conditions and so lengthens its productive lifecycle. After proving the WaveSpring technology with CorPower, the NTNU inventor Jörgen Hals Todalshaug joined the company as Lead Scientist.
