“…Moving from the recent intense research on the SSG (Buccino et al, 2012;Buccino et al, 2015a;Buccino et al, 2015b;Oliveira et al, 2016), a slightly different device, denominated Overtopping BReakwater for Energy Conversion (OBREC), is under development (Vicinanza et al, 2013a;Vicinanza et al, 2014, Contestabile et al, 2017a. It is an innovative breakwater with a special shape designed to accommodate an overtopping wave energy converter (OTD) and all the instrumental equipment for the energy conversion.…”

“…Considering the non-conventional geometry of the OBREC, research work into aeration, local effects and extreme wave events on a full-scale device have been considered essential to have a complete knowledge of the overall wave-structure interaction phenomena. However, the relations presented in this paper for the hydraulic response of the device and the results on loading acting on the OBREC from test AAU2014 (Contestabile et al, 2017a) and from Allsop et al (1997) have been used to design the device in full-scale at the port of Naples in Italy.…”

“…6). The aim is to acquire and analyze pressure data to compare it with existing formula in literature and validate pressure data measured in the experimental test in small scale in 2012 (Vicinanza et al 2014) and in 2014 (Contestabile et al, 2017a). Two highresolution cameras are used to capture the wave profile when waves overtop the ramp and impact on the vertical wall.…”

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.

“…Apart from dissipating the wave energy, the breakwaters are also used for loading and unloading of cargo. Breakwaters have application in various other fields such as coastal rehabilitation of mangroves [15] and energy production from overtopping waves [14]. Apart from conventional rubble mound breakwater, new hybrid type breakwaters have also been developed.…”

Economic development of a country is directly dependent on the functioning of the ports and transportation facilities available. It is of vital importance to protect the ports and harbors and thereby providing safe and effective loading and unloading facilities. Proper protective measures like breakwaters have to be constructed to protect and maintain tranquility conditions inside the harbor. Apart from conventional rubble mound breakwater, newly developed hybrid type breakwaters are also used as protective structures. Final layout of the structure is determined only after prior physical model studies. Soft computing techniques, widely used in the field of prediction, are recently used in the field of breakwater studies for the prediction of transmitted wave height, damage analysis etc. Present work deals with the transmitted wave height prediction of a tandem breakwater using hybrid PSO-SVM model. Effectiveness of the models developed were measured using various statistical parameters such as RMSE, MAE, CC and SI. Results showed that, from among various kernels used, model developed with polynomial kernel showed better correlation.
