Bureau Veritas has issued its first Approval in Principle for an Ocean Thermal Energy Converter (OTEC) to a 1MW plant developed by the Korea Research Institute of Ships and Ocean Engineering (KRISO).
The plant will be installed off the coast of South Tarawa, Republic of Kiribati, in the South Pacific Ocean. It consists of an octagonal 6,700-tonne four-deck floating platform moored in a water depth of 1,300m. A 1,000m pipe with a 1.2m diameter will be used to pump cool water up from the depths to the plant on the platform.
Bureau Veritas’ engineers verified a metocean/hydrodynamics analysis, mooring analysis, stability analysis, and examination of the riser design and system design concept.
Approval in Principle implies that the design is feasible, achievable, and contains no technological show-stoppers that may prevent the design from being matured. It also means that the design is deemed to be suitable for use in the metocean conditions that the unit facility will be located in.
Bureau Veritas said KRISO’s 1MW OTEC plant is the first practical level of its kind on a pathway to build a 100MW commercial system.
