Oscillating Water Column

Technology Description A 1 5MW Multi Resonant Chamber MRC using Oscillating Water Column OWC principles Consists of 3 x 500kW independent chambers each with a Dresser Rand HydroAir turbine driving an induction generator Full power conversion system delivers grid compliant power 1 5MW 33kV 60Hz to shore Device is tension moored to maximise power capture and minimise footprint All maintenance is done on board No moving parts in the water Turbines are low speed 300rpm high efficiency 75 and low noise

Mooring Configuration Proprietary
Optimum Marine/Riverline Conditions Installation site must be 50m water depth preferably 1km offshore to avoid coastal refraction and reflection of waves The optimum wave climate would be 3m 9 5secs period
