Description

The Spar and Sphere offshore platforms are feasible concepts for the demonstration of a near full size OTEC plant to determine its validity and to gather data for use in the construction, design and operation of commercial OTEC plants. A hull size suitable to support a 100 MWe net output plant was chosen. Either 50, 25 or 12.5 MWe power modules could be used. Selection of 50 MWe modules would permit the testing of equipment recommended for the commercial plant. The use of 25 MWe modules would permit optimal hull volume utilization. The size hull selected for both platforms represents ... continued below

Description

The Spar and Sphere offshore platforms are feasible concepts for the demonstration of a near full size OTEC plant to determine its validity and to gather data for use in the construction, design and operation of commercial OTEC plants. A hull size suitable to support a 100 MWe net output plant was chosen. Either 50, 25 or 12.5 MWe power modules could be used. Selection of 50 MWe modules would permit the testing of equipment recommended for the commercial plant. The use of 25 MWe modules would permit optimal hull volume utilization. The size hull selected for both platforms represents a reasonable increase above the pilot plant, providing design and construction problems similar to those that may be found in a hull size commercial plant. Since the hull size is substantially smaller than the projected commercial plant size, the possiblity of constructing the vessel of steel was presented. However, it is already determined that the full size hull shall be constructed principally of reinforced concrete and thus to fully demonstrate the feasibility of both construction techniques and operation, concrete was chosen for the demonstration plant. The superstructure of the sphere is all steel and for the spar, concrete with a steel deckhouse. The cold water pipe for both platforms is fiberglass. Construction of the hull and installation of all equipment are proposed to take place in three separate phases at three different sites. The overall plan proposes: (1) a shoreside construction site; (2) an offshore site in sufficient water depth to complete the hull erection; and (3) installation of the cold water pipe at the demonstration site.
