OTEC(Ocean Thermal Energy Conversion) system using the temperature difference between cooler deep and surface ocean waters is one of the renewable energy. But in Korea, OTEC system can not apply except in winter because surface sea water temperature is not enough. C-OTEC(Combined OTEC) system is that utilizes temperature difference between sea water and the condenser of power plants via working fluid. It can be a good alternative in the warm surface sea water for Mid-latitudes region like Korea. In this study, a marine survey using multi-beam echo sounder, single-beam echo sounder and sparker seismic wave is performed and sea water intake pipe line is proposed for the 10kW C-OTEC Pilot Plant.
