WavEC Offshore Renewables Conducted Biofouling Tests at AW-Energy’s site in Peniche



The tests were measuring the amount of marine growth attaching to the WaveRoller® panel and its seals. The tests were conducted in connection to the University of the Highlands and the Islands’ MERIKA (Marine Energy Research Innovation and Knowledge Accelerator) project.

Information gathered with the biofouling tests is vital, as the panel functions might change if the object’s mass is increased significantly. Lifting the device for maintenance can also prove tricky if the expected weight is exceeded.

-  The goal was to find out the number and weight of species attaching to the panel per square meter. The same tests were conducted with the device’s seals, says AW-Energy’s Environmental Specialist Essi Paronen.

Scaled down test panels demonstrating the WaveRoller® surface, along with the seal materials, were submerged in the test site to measure the amount and impact of biofouling. The tests identified the main type of species colonizing the WaveRoller® device.

-  This information can be used to choose the most appropriate anti-fouling protection and helps to plan the device’s maintenance operations.

The MERIKA tests will be concluded in August.
