The primary objective of this conceptual design sutdy was to maximize the cost effectiveness of the two OTEC platform configurations, the ship and the spar with detachable modules, as they apply to commercial plants with 400 MW/sub e/ net output. Early examination of potential concept arrangements for the 400 MW/sub e/ plant using 25 or 50 MW/sub e/ power modules revealed that traditional materials and arrangements would not be capable of attaining cost effective designs. Immersing some of the power system components in the sea water revealed remarkable design opportunities. The ship-type conceptual design utilizes immersed heat exchangers (50 MW/sub e/) with a combined strong-back and water duct structural design in concrete to provide a platform which is estimated to cost 690 $/kW for each of the 2nd to 8th units for a New Orleans site. The spar-type conceptual design, which inherently utilizes immersed heat exchangers in the detachable modules, incorporated immersed ammonia storage tanks to assist in providing net buoyancy for the core of the spar as constructed in concrete. A cost of 801 $/kW is estimated for the spar-type platform at a New Orleans site. Both platform concepts utilize a central control facility in the OTEC farm which provides living accommodations for service personnel and all on-site maintenance ships and supplies. No accommodations are planned for permanent personnel on the individual commercial platforms.
