Bodycote, a provider of heat treatments and thermal processing services, is targeting the marine renewables sector after securing work with wave energy firm CorPower Ocean.

The UK-headquartered firm, which has built a long-term track record in automotive, aerospace, energy and broader industrial sectors, is now breaking into ocean energy after helping Swedish developer CorPower optimise key components in its Wave Energy Converters (WECs).

CorPower says its WECs, inspired by the pumping principles of the human heart, offers five times more energy per tonne of device compared to previously known technologies. Incorporating a series of unique features to boost storm survivability and power capture, the WECs also benefit from thermochemical treatment to protect against the harshest marine conditions.

CorPower Ocean’s senior procurement and quality engineer, Thomas Lindahl said: “After our initial collaboration we have now worked with Bodycote at a number of plant locations across Sweden to develop mechanical components for our WECs using Corr-I-Dur. This thermochemical treatment simultaneously improves corrosion resistance and wear properties by generating an iron nitride-oxide compound layer.

“Durability and robustness are of paramount importance in the wave energy sector, and effective protection of devices in the hostile ocean environment has always presented a major challenge to our industry.

“Corr-I-Dur has proved a particularly favorable solution being specifically designed for components subjected to a corrosive environment in combination with wear. From a commercial perspective, solid proof of the long-term resilience of our WECs makes them infinitely more valuable. We believe this collaboration will play a crucial role protecting our WECs during our next phase of testing in the Atlantic Ocean, and for the years to come.”

Bodycote’s president for northern and eastern Europe, Paul Clough, added: “By using Corr-I-Dur, CorPower was able to design mechanical components such as pistons, guides and linkages, that are suitable for the world’s harshest environments for metal.”

CorPower Ocean is now ramping up operations for its flagship HiWave-5 demonstration project in northern Portugal to propel its wave technology to a bankable product offering by 2024.

The €16 million ($19 million) project includes investment to build a world-class wave energy hub in the Port of Viana do Castelo, involving R&D, manufacturing and servicing facilities for the long-term development of supply and service capacity for commercial wave energy farms.
