Abstract

This paper discuss wave loadings acting on the Wave Energy Converter (WEC) Seawave Slot-Cone Generator (SSG). The SSG is a new type of structure for wave energy conversion based on storing the incoming waves in several reservoirs placed one above the other. The wave forces on the main structure can be estimated using experiences from coastal protection structures, but the differences between the two types of structures are so large that more reliable knowledge on the wave forces is desired. Model tests were carried out to measure wave loads using realistic random 2D and 3D wave conditions. Pressure cells were placed in order to achieve information on impact/pulsating loadings. Data analysis identifies different structure response depending on wall geometry and location. Results discussed here derive from preliminary analysis conducted using only a part of the whole data set. The research is intended to be of direct use to engineers analyzing design and stability of the pilot plant under construction at Kvitsøy island, partly funded by the EU 6th framework program (WAVESSG).
