Model Test of a Generic Shelf-Mounted OTEC (Ocean Thermal Energy Conversion) Platform

摘要

A model test of a generic Ocean Thermal Energy Conversion platform was performed in CBI's wave tank. The basic model consisted of four vertical columns placed in a square configuration. This model allowed the study of wave cancellation and multiple scattering. The spacing of the columns influences the wave force and may minimize the force at a given (design) wave period. The variation of other model configurations from the baseline model consisted of square blocks of different heights representing the submerged power modules of OTEC. The modules of different heights produced different blockage to the incoming waves. These modules were solid or uniformly perforated. Thus, the same blockage could be achieved by two different sizes of solid or perforated modules. Most of the modules were totally submerged while one extended above the water surface. The purpose of the test was to study the effect of, at least, three parameters on the global wave forces on the platform: (i) the size, (ii) the type, and (iii) the location of the modules.
