Project Description / Objectives:
The WRAM is a powerful, single-bodied heaving buoy point absorber with a pneumatic PTO, intended for utility-scale arrays in deep-water ocean sites. The main CAPTOW objective is to optimise the control algorithms and PTO systems, backed by empirical tests. Simulations will predict performance, loads and forces, and are being validated by tank tests with true scale models.
– Predicted performance, loads and forces from WEC-Sim, CFX, RANSE and SPH solvers validated by tank tests.
– Assessment of RANSE and SPH solvers.
– Control algorithms developed and tested using real-time hybrid systems test rig.
– Prototype PTO system designed, built and tested.
– Techno-economic evaluation and estimated LCOE.
Update on Work to date
– Kick-off meetings, consortium agreement, cloud-based server.
– WEC-Sim modelling well advanced.
– Scale model built, performance tank tests completed.
– Now progressing with CFX, RANSE, SPH simulations.
