Wavegen Limpet OWC

QUB and Applied Research and Technology

RPS was appointed to undertake design of an oscillating water column wave power plant with approx 600kW generating capacity.

Rock drilling, blasting and excavation was required at an exposed coastal site to approximately 5½m below MLWS to create a rock pocket for construction of the wave energy device.

RPS designed the three chambered device of 18m wide x 6m deep using the latest Finite Element analysis software and extreme wave loadings impacting on the front wall. Internal pressure and suction also was considered from the moving air column.

The design of the device and construction technique allowed for a protective rock face during construction. On completion this rock face was removed by blasting to create the tapering entrance channel.
