“…(12) which is suggested to be used as new design formula instead of Equation (7). As a point of strength, the new tool holds for both impact and non-impact conditions; on the other hand, it has to be pointed out that the determination index is some low (R 2 = 0.61) and the lack of dependence on the linear thrust parameter may lead to largely overestimate the variance of steep standing waves, which have low ξ and low LTP.…”

Abstract:The reliability of Computational Fluid Dynamics (CFD) in reproducing qualitative and quantitative features of loadings exerted by waves on Seawave Slot-cone Generators (SSG) has been investigated via 17 numerical experiments, conducted with the suite Flow 3D. The geometry of the Wave Energy Converter (WEC), as well as the characteristics of the foreshore in front of it, were identical to those used by the authors in a laboratory study, carried out on a small scale model of a pilot plant to be located along the West Norwegian coasts; the similitude of the layouts allowed an in depth comparison between the results. A good agreement has been generally found between physical and numerical experiments, apart from some aspects of the wave-structure interaction that, however, can be considered secondary for engineering purposes.

“…Patented by WavEnergy SAS (Stavanger, Norway), this OTD includes a number of reservoirs placed on the top of each-other, which capture the water during the up-rush phase; on its way back to the sea, the fluid passes through a low-head turbine, spinning it and producing electricity [12][13][14].…”

“…Unfortunately, environmental issues required locating the SSG pilots to another location, but, after more than ten years, these projects have not been realized. Although several studies (Kofoed, 2002;Margheritini et al, 2009) suggest that the use of multiple reservoirs improve the efficiency compared to structures with one reservoir, on the other hand, this complex geometry leads the device to be still not economically competitive with respect to other WECs embedded into breakwater.…”

The Overtopping BReakwater for Energy Conversion (OBREC) is a new typology of overtopping wave energy converter (OTD) integrated into a traditional rubble mound breakwater. The device can be considered as an innovative non-conventional breakwater that has the same functions as the traditional structures with the addedvalued of the energy production. The paper presents a comprehensive overview of the OBREC, offering a synthesis of the complete design process, from the results of the two complementary test campaigns in small scale carried out in 2012 and 2014 at Aalborg University, to the description of the full-scale device installed in Naples in 2016. The device represents the first OTD device in full-scale integrated into an existing rubble mound breakwater and it has been equipped by an instrumental apparatus to measure its response to the wave interaction. The monitoring of the full-scale device in the port of Naples, particularly during storm conditions, is aimed to study the scaling effects in wave loading and the overall performance of this breakwater-integrated OTD, included performance in terms of the energy production.

“…Wave energy which is one of the renewable energies attracts attention as a promising resource that can reduce CO2 emissions. Wave energy converter (WEC) which converts wave power into electric power has been developed all over the world and many types of WECs [1] such as the movable body type [2,3] and the overtopping wave type [4] were proposed. There is an oscillating water column (OWC)-type wave energy converter as one of the WECs.…”
