international classification society Bureau Veritas has issued its first
Approval in Principle for an Ocean Thermal Energy Converter (OTEC). The approval
applies to a 1MW plant developed by the Korea Research Institute of Ships and
Ocean Engineering (KRISO) which will be built for installation off the coast of
South Tarawa, Republic of Kiribati, in the South Pacific Ocean.
Matthieu de Tugny, Senior
Vice-President and Head of Offshore, Bureau Veritas,
says, “OTEC technology offers the potential for round-the-clock
clean renewable energy from the ocean. We are excited to deploy our expertise in offshore energy,
met-ocean studies and structures to help bring this project which will deliver
clean electricity to remote areas to fruition.”
Ocean Thermal Energy
Conversion (OTEC) is a sustainable way to produce electricity from the
difference of temperature between deep cold and warm surface seawater. A working
fluid is successively vaporised and condensed in a thermodynamic cycle, with
the gas phase driving a turbo-alternator producing electricity.
KRISO’s 1MW OTEC plant
is the first practical level of plant on a pathway to building a 100MW
commercial system. It consists of an octagonal 6,700 tonne four deck floating
platform 35 m across moored 6 km offshore in a water depth of 1,300 m. A 1,000
m pipe 1.2 m in diameter will be used to pump cool water up from the depths to
be fed to process plant on the platform.
Approval in Principle
for Bureau Veritas implies that the
design is feasible, achievable,
and contains no technological
show-stoppers that may prevent the design from being matured and that
the design is deemed to be suitable for
use in the metocean conditions that the unit facility will be located
in. Bureau Veritas’ engineers verified a metocean/hydrodynamics analysis,
mooring analysis, stability analysis, and examination of the riser design and
system design concept.
KRISO (Korea Research Institute of Ships & Ocean
engineering), established in 1973, is a government-funded research institute in
the Republic of Korea and the leader in technology development in ships and
ocean engineering. Its major research areas are
Environment-friendly Advanced Ship Technology, Offshore Plant
Engineering Technology, Ocean Energy Technology, Maritime Traffic Safety and
Marine Accident Response Technology and Underwater Vehicles and Marine
Equipment Technology. www.kriso.re.kr/eng/
