Innovative Wave-Absorbing Structures

Project funded by the European Union’s Horizon 2020 research and innovation programme under Marie Skłodowska-Curie Grant Agreement No. 842967

The InWAS project objectives consisted in revisiting design optimisation for two archetypal wave energy converter (WEC) principles: (a) in heaving point absorbers (HPAs), which are mechanical structures operating in heave, non-cylindrical hull geometries would be investigated, which may allow for optimal power absorption using smaller control actuation, hence at reduced capital cost; (b) in oscillating wave surge converters (OWSCs), which exploit the horizontal wave-induced fluid motion in nearshore zones, flexible, bio-inspired structures would be developed, which can improve survivability, and have excellent potential in terms of protection against coastal erosion, as previously pioneered at PMMH.
