Significant wave height up to 8.2 meters and single waves up to 15 meters.
Cross current up to 3.1 knots.
The prototype project ran from 2015 to 2019 and included several development iterations increasing the energy production and durability in each iteration.
In the first iteration two energy collectors were each fitted with a 4 m2 plate. In the second and third iteration a total of 4 energy collectors were each fitted with a 7 m2 plate. In our last iteration the energy collectors were each fitted with a 8.5 m2 plate.
The last version was a 100-m string with the possibility of attaching 6 energy collectors. In the last iteration we tested 4 energy collectors simultaneously.
Different storm protection systems were tested in parallel on the energy collectors. The storm protection system reduces the plate area when forces get too strong.
Data from the loads and the energy production was collected on a computer on the inner buoy and uploaded to a server. The data was analysed and compared to the predictions from the Wavepiston Load and Energy Tool developed in collaboration with the Technical University of Denmark. The identified improvements in the design will be implemented in the next projects at full scale in Gran Canaria.
