A baseline design was developed for an Ocean Thermal Energy Conversion (OTEC) pilot plant. The plant was configured as a floating platform for large-scale, at-sea, practical demonstrations of OTEC system operation. This study reports on model tests that were conducted at 1/30 scale in a model basin in order to develop confidence in the seakeeping and survivability qualities of the design. Waves were produced to simulate a variety of ocean conditions, including a 100-year storm sea with hurricane waves to a maximum height of 65 feet. The platform survived all simulated conditions, although it was observed that bilge keels, a shaped bow and additional hull length would improve seakeeping in hurricane seas. Quantitative data were obtained on ship motions, cold-water- pipe loads and motions, mooring forces, and seawater system pressures.
