Offshore Thermal Energy Conversion Vacuum Structure

Kailua-Kona, Hawaii

The Pacific International Center for High Technology Research was awarded a contract to build an Offshore Thermal Energy Conversion demonstration plant for generating electricity using the water temperature difference stored in tropical oceans. The process uses warm surface seawater flash-evaporated under vacuum pressure and cold seawater to condense the water vapor after it passes through a turbine generator. BergerABAM designed a concrete vacuum structure to meet the challenging airtight tolerances required for the successful operation of this steam generation process.
