Wave energy is referred to the energy transported by wind waves, which power can be extracted and converted into electricity or pressurized water. Wave power comes from the up-down movement of the water (potential energy) or the water movement beneath them (kinetic energy). Wave energy is always present in any water body, being a promising source of clean energy anywhere in the globe: waves are ubiquitous and present 24/7 all year-round. Global wave energy potential is estimated on 2.11TW, with 427GW available at North and Central America coasts, and 374GW in South America coastlines (Gunn & Stock-Williams, 2012).

Today, wave energy converter technologies (WECs) are at different development stages, having a vast range of concepts and formats, as well as energy capture and generation possibilities. It is worth mentioning that these devices must operate under a wide range of environmental conditions, including natural hazards like storms and tsunami, and therefore survivability is one of their main challenges, in which understanding local conditions plays a significant role. The Ocean Energy Systems, international working group part of the International Energy Agency, suggests a technological classification for WECs: attenuators, overtopping, oscillating water column, oscillating wave surge converters, point absorbers, and other concepts [2]. Depending on the scale and functionality, WECs could potentially deliver energy to an electrical network, or otherwise be the source of clean energy and/or freshwater at open ocean, triggering and supporting community and industrial development where these resources are scarce.
