AW Energy rides the waves
WaveRoller passes year-equivalent power take-off testing
Finnish developer AW Energy has completed the equivalent of one year’s accelerated testing of the power take-off (PTO) for its WaveRoller device.
The developer is conducting comprehensive tests on the PTO before the first commercial-scale 350kW WaveRoller is installed off the coast of Peniche in central Portugal.
AW Energy said the PTO has been tested up to wave heights of up to eight metres at its rig located near Helsinki.“When waves go above the height of 2.5 metres the sea conditions are considered rough”, said chief technology officer Chris Ridgewell.
“We’ve learned an awful lot from this testing phase, the test facility proved very useful.”
The objective of the testing is to uncover hidden issues that are difficult to find during the design process.
The typical types of failure could be fatigue damage of mechanical and hydraulic components, failure of control systems and sensors, and errors in the control algorithms that reduce power output.
