The principal objective of this thesis has been to study and research on Water Energy Convertors(WEC) devices, carrying out theoretical and analytical approximations. Nowadays, the demand of renewable energy resources is increasing and tent to increase deeply in the next couple of years. This has been forced mainly by oil crisis and by the need of creating energy by clean resources. The main proposal has been to find out the maximum efficiency level for two different types of convertors and energy transmission process from point absorber to drive generators. Carrying out the dimensioning process of each device separately, according to exigencies demanded for each one. The entirely thesis is oriented completely from an application point of view, using the engineering background of maritime technology, mechanical and offshore industry. An interesting arriving point was obtained from Scatter diagram, an optimal potential energy range was captured by wave's motion with wavelength from 7.5sec to 10.5sec period. This range will be the most appropriate range of work for WEC. The main motivation of this report is to provide two different WEC application approach from academicals perspective to industry.
