1000 Mega Watt Power Plant OTEC Support Semi-Submersible Platform DSI is offering a proposal for a One Thousand Megawatts power plant that can be built in the deep waters off the East coast of Tamil Nadu or other tropical countries and islands. The power plant will be designed to produce 1000 MW on a platform and can be located about 30 Kilometers off the coast. This will be on a Floating semi-submersible Offshore Platform type in class ABS/Dn. V that resists 1000 years return storm, quite stable for the harsh environment of the Bay of Bengal and of the Tropical oceans. (Experimentally Verified) A 100 METERS X 500 METERS VERY LARGE FLOATING VESSEL TO SUPPORT 1000 Mega Watt OTEC POWER PLANT 10
