OTEC Turbine and Two New Heat Exchangers Arrive at the Makai Ocean Energy Research Center in Hawaii

Makai’s Ocean Energy Research Center (OERC) in Kona, Hawaii has received several major pieces of equipment for its Ocean Thermal Energy Conversion (OTEC) demonstration plant. Two new heat exchangers (2-megawatt thermal duty each), and a 100 kilowatt ammonia turbine-generator have arrived and are in various stages of installation and testing. To date, Makai has tested four condensers and three evaporators at the OERC, each made of either aluminum or titanium. The facility has been designed… Continue reading

Successful repair of NELHA’s 40-inch deep-seawater pipe

Recently the repair works on NELHA’s 40-inch deep-seawater pipe were successfully completed. Operating at 150M depth and using remotely operated vehicles, it was quite an undertaking.

The high-density 1.2-mile-long polyethylene pipe, installed in 1987, extends to depths of 2,000 feet. The pipeline is the backbone of the Natural Energy Laboratory of Hawaii Authority’s coldwater aquaculture and research projects.

Surveys of the pipeline in December 2007 showed the mooring bridles, which help hold the pipeline to… Continue reading
