One of the possible options for generating electrical energy from ocean thermal gradients requires the use of a floating offshore platform. The platform would contain all OTEC (Ocean Thermal Energy Conversion) systems and power cycle components and consist of the hull, seawater, station-keeping, platform service, and mission support subsystems. It would be stationed at one of the designated OTEC sites, and would transmit the generated electricity to the shore power networks by means of an electrical transmission cable. The objective of the present study is to investigate the station-keeping subsystem (SKSS) requirements and develop preliminary SKSS designs for the two Modular Experiment Plant (MEP) candidates of 10/40 MW/sub e/ capacity for deployment at a specific site. The two MEP hull candidates are a Barge type platform and a Spar shaped hull with external heat exchangers. The specific site assigned for this study is Puerto Rico. The preliminary SKSS designs are developed for both platforms as follows: (1) an 8-leg spread catenary mooring system for the Spar, and (2) a 12-leg spread catenary mooring system for the Barge. Applicability of these designs to larger capacity commercial OTEC platforms is also investigated.
