Oscillating Wave Surge Converter
• Bottom hinged flap • Sea bed mounted

• Moves in pitch • PTO - Hydraulic
• Near-shore 10 – 15m
• Array of point absorbers

Queen’s University Belfast

Research objective
 To gain an understanding of the hydrodynamics of the oscillator so that this knowledge can be used to optimise its design with respect to performance.

Queen’s University Belfast

Physical modelling
 Performance seas

 Monochromatic waves  Wave force
 Forced Oscillations – new model

 Pitch stiffness, Natural pitching period  Survival seas – load tests
