Wave Tank Testing Report for Controls Validation of a Heaving Point Absorber


The core objectives of this project is to improve the power capture of three different wave energy
conversion (WEC) devices by more than 50% using an advanced control system and validate the
attained improvements using wave tank and full scale testing. In parallel, we will bring along the
development of a wave prediction system that is required to enable effective control and test it at full

The purposes of this report are to:
1. Plan and document the 1/25th scale device testing at the wave-tank facility;
2. Document the test article, setup and methodology, sensor and instrumentation, mooring,
electronics, wiring, and data flow and quality assurance;
3. Communicate the testing results between the associated members;
4. Facilitate reviews that will help to ensure all aspects (risk, safety, testing procedures, etc.);
5. Provide a systematic guide to setting up, executing and decommissioning the experiment.
