Ocean Thermal Energy Conversion power system development. Phase I: preliminary design. Final report

This report summarizes the preliminary design for the Ocean Thermal Energy Conversion (OTEC) Demonstration Plant project. The scope of Phase I was the conceptual design of: (1) full sized power system module; (2) scaled (5 MWe nominal) proof of concept power system; and (3) 1 MWe heat exchanger test article. Included were all components and subsystems specifically involved with the generation of power (warm and cold seawater pumps, heat exchangers, turbine/generator, etc.) The scope of Phase I preliminary design is: (1) conceptual design of a commercial size power system between 40 to 50 MWe(net) with costing on prototype, first production, and eighth unit; (2) preliminary design of a 10 MWe net modular application power module with tube material of titanium, and analogous to the commercial size power module. The heat exchangers are to be immersed and costing data should be provided for first unit and eighth unit; and (3) preliminary design of a heat exchanger test article
