The integration of the wave energy devices (WECs) into existing or new coastal structures could be a realistic solution to reducing their very high costs (Vicinanza et al., 2014). Nowadays very few devices have been constructed in full scale and no one is in commercial phase. The paper presents the prototype of an innovative breakwater for wave energy conversion installed in the port of Naples in 2015. The device is denominated OBREC (Overtopping BReakwater for Energy Conversion) and represents embedded into a breakwater, which exploits the wave overtopping process. This article shares the entire design process, from concept, the preliminary design in small scale to the full-scale prototype construction. [ABSTRACT FROM AUTHOR]

The wind energy industry is growing worldwide. Recently, a number of physical and numerical modeling studies have been carried out in Europe to implement the offshore wind turbine technology, as well as the wind resource. Accordingly, the consideration of the possible environmental impacts of this technology on the marine environment, already affected by several anthropogenic pressures (e.g. fishery, maritime traffic) becomes increasingly important. Main goal of this paper is to provide an overview of the offshore wind farm developments and the associated environmental impacts at European level. The Italian state of the art is also presented.

This article discusses research which examined the random wave computational fluid dynamic (CFD) simulations for the structural response of seawave slot-cone generator (SSG), a wave energy converter. Topics discussed include the wave energy converter based on the overtopping principle and equations based on results of physical model tests conducted with regular waves.

The article discusses research which analyzed the wave flume-generated seiching. Topics discussed include the mode of the seiche which includes the number of nodes it has within the system, modes of free oscillations in closed basins and the behavior of low frequency motions in the large wave flume by the spectral analysis.
