ABSTRACT:
A method and apparatus for an OTEC platform are disclosed. The platform provides the high stability needed for OTEC applications. The platform includes a centrally located cold water pipe. The cold water pipe is suspended from a center column that is open at both the top and the bottom. The platform further includes multiple columns surrounding the cold water pipe. The columns extend from above the sea surface to deep depths below the sea surface. The OTEC platform also includes multiple power modules. The power modules are submersed below the sea surface and are utilized to provide stability to the platform. Moreover, the power modules are dispersed around the columns to provide additional stability. Various embodiments of the arrangement of the columns are also disclosed. The columns may be proximate the center column or may be placed an extended distance from the center column.
