Design of the Point Absorber Wave Energy Converter for Assaluyeh Port

The research explained in this paper was carried out to analyze and design a point absorber wave energy convertor for Assaluyeh coastal on Persian Gulf. The geographical conditions of this region have somelocal short waves which may be ideal to use this type of energy convertor. According to the collecting of wavedata and using an optimized buoy, it is concluded that the adjustments on damping and natural frequency havemore effect on average heave displacement. Therefore, by changing the shape of flat buoy to conicalcylindrical, the drag coefficient that has direct effect on the damping of the buoy could be reduced. Regardingthe length to diameter ratio of 1.7 for the selected buoy, changing its shape from flat cylinder to conical cylindercauses the drag coefficient to decrease by 50 %, which is followed by 20% increase in average amplitude of heave motion from 0.524-0.625m. This increase in average amplitude heave is efficacious in increase power buoy around 45 watts
