Glossary and Helpful Notes for Readers
What is a Wave Energy Converter?
A wave energy converter is a device designed to capture kinetic energy from ocean waves and convert it into electrical power. WECs come in many shapes and sizes, including point absorbers, attenuators, oscillating wave surge converters and others. Testing such devices at Wave Hub Cornwall helps engineers compare performance and durability across different concepts under real sea conditions.
Why offshore testing matters
Offshore testing provides critical performance data that cannot be reliably obtained in onshore facilities or small‑scale rigs. Realistic wave action, seabed interactions, corrosion, biofouling and maintenance demands all influence device viability. Wave Hub Cornwall’s offshore environment is therefore essential for validating reliability, safety and long‑term cost effectiveness.
