Floating platforms housing hydrogen plants operated with 100 MW of OTEC (Ocean Thermal Energy Conversion)-generated electricity have been conceptualized. These plantships, deployed throughout the tropical oceans, could provide a significant source of energy in the form of liquid hydrogen. Large suspended pipes would transport cold seawater from depths of 1000 m to the heat exchangers onboard. A 285000-tonne ship-shaped vessel is first proposed. It provides deck space for the OTCE plant, hydrogen plant, storage,and crew quarters. A length of 250m and a beam of 60m are sufficient to accomodate five seawater sumps. The operational draught is 20m. Four 3000PSthrusters permit grazing at one-half knot and some maneuvering capability. A more compact plantship jet-propelled by the momentum flux of the OTCE discharge is also presented. The length is reduced to 200m, for a displacement of 225000 tonnes. Only one sump is required, and warm seawater is fedthrough lateral openings.
