DNV GL validates WaveRoller

AW Energy WaveRoller’s load calculation and structural analysis methods have been validated by DNV GL.

DNV GL used its wave energy modeling tool, WaveDyn, to simulate the loads on Wave Roller wave energy device structure.

The response of the structure was then predicted and compared with the information gained through Wave Roller’s sea trials.

“Suitable agreement with measurements has now been confirmed, thus validating the numerical methodology for design purposes,” AW Energy’s press release reads.

The numerical models, created and now validated by DNV GL, are currently being used for the load and structural assessment of the commercial scale WaveRoller design, with the first commercial roll-out of the 350 kW being on track for 2016, it is stated in AW Energy’s press release.

The R&D Manager Tuula Mäki of Finland-based AW Energy said: “These results are especially valuable since they will help in optimizing the design of the technology. Keeping safety factors at a reasonable level by reducing uncertainty in the modelling process will also cut investment costs, further stimulating the technology’s progress towards large scale roll-out.”

DNV GL is a ship and offshore classification society, and technical advisor for the energy value chain including renewables and energy efficiency, as well as the global oil and gas industry.
