9000-SHP CLOSED CYCLE POWER UNIT BEING DEVELOPED FOR LNG TANKERS

The design of a 9000-shp closed cycle power unit for use as a refrigeration system aboard LNG tankers, with a secondary objective to define a technologically advanced closed cycle gas turbine main propulsion plant, is described. The closed cycle engine, called the Brayton Cycle engine, is described in full, including an explanation of how the system operates, as well as advantages of the system. This system would eliminate LNG boil-off by refrigerating the boil-off instead of reliquefying it, thereby utilizing advantages of safety, low weight, and size and design simplicity over a reliquefication unit. The operation of the refrigeration unit, as well as descriptions of other features and advantages, are also included in the article.
