“…These buoys are able to record different parameters, such as significant wave height H s (measured in meters), peak period T p (measured in seconds), and average wave direction δ m . At first, recording period was about 3 h, then (with the replacement of all the wave buoys with more technological ones) it was about every 30 min [40]. In this way, RON was able to describe wave climate with a higher time resolution (but the spatial resolution still remained low).…”

Abstract:The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around the island. A point absorber is present in order to exploit this source. Two scenarios are presented, with two different levels of energy production.

“…These estimates can be used to quantify the accuracy of the model chain, as well as to provide a way to compute H S (T R ) curves for geographical locations not coinciding with wave buoys by making use of Equation (4), and of the standard deviation σ(T R ) given by Equation (8). Figure 7 reports some examples.…”

“…As a consequence, it has become a common practice [8,9] to use data (in the following indicated as "indirect data" or "model data") originated from global or regional wave models, which are in turn driven by meteorological wind models. Global and regional wave data are readily available and this favours their extensive use by ocean engineers and researchers.…”

Abstract:Estimating the extreme values of significant wave height (H S ), generally described by the H S return period T R function H S (T R ) and by its confidence intervals, is a necessity in many branches of coastal science and engineering. The availability of indirect wave data generated by global and regional wind and wave model chains have brought radical changes to the estimation procedures of such probability distribution-weather and wave modeling systems are routinely run all over the world, and H S time series for each grid point are produced and published after assimilation (analysis) of the ground truth. However, while the sources of such indirect data are numerous, and generally of good quality, many aspects of their procedures are hidden to the users, who cannot evaluate the reliability and the limits of the H S (T R ) deriving from such data. In order to provide a simple engineering tool to evaluate the probability of extreme sea-states as well as the quality of such estimates, we propose here a procedure based on integrating H S time series generated by model chains with those recorded by wave buoys in the same area.

“…At the beginning, the available energy at the site of interest is estimated on the basis of annual offshore wave climate toward the coast [9]. In particular, the wave mean power distribution around the island of Sicily is shown in Figure 1b, from which the values in front of Giardini Naxos (red dot) are extracted.…”

“…Such a form of energy is not uniformly distributed throughout the world [3][4][5][6] and being generally weak in enclosed seas, is therefore scarcely used for energy exploitation. In particular, the wave energy availability in the Mediterranean Sea, in terms of mean annual wave power, gives values in a range of 2-12 kW/m [7][8][9][10][11][12][13]. The areas of the highest energy are located on the western coast of the island of Sardinia, near Alghero (Italy) [14,15], where the mean power is about 12 kW/m.…”

A feasibility study for installing Wave Energy Converters (WECs) in a Mediterranean port is presented here. The final aim is to evaluate the possibility of building a green touristic infrastructure in a site having ordinary wave energy. In particular, the site of interest is Giardini Naxos, which is located in the northern Ionian coast of the island of Sicily (Italy). A preliminary estimation of the available energy has been carried out. The chosen type of WEC device is the Oscillating Water Column (OWC) system, which is found here to allow for good integration with the vertical breakwater needed for the extension of the existing port. Its feasibility is evaluated from the structural and economic point of view. Towards this aim, the system is tested in the laboratory for estimating the reflection coefficients and the pressures on the structure, which allow us to carry out the optimization of the OWC breakwater. Furthermore, the air turbine noise is estimated and an attenuation chamber is designed to reduce such noise to within acceptable levels. The economic feasibility study allows for an evaluation of the recuperation period of the investment, which is slightly less than the service life of the WEC device.
