APPLICATION OF CONDENSER SCOOP COOLING SYSTEM FOR STEAM TURBINE (IN HAMPTON MARU, ETC)

Sumitomo have built a series of five 168,000-dwt ore/coal/oil carriers since 1971, each of them with a scoop cooling system for the main condenser. Test results of the system, from the sea trials of Hampton Maru, the first ship of the series, were published in 1972. In the present article, the further development of this scoop system during the building of the series is described. To obtain the most suitable configuration, in respect of important variables such as cooling pipe diameter, lip-length/pipe-diameter ratio, and outlet angle, the system was modified in the four later ships on the basis of the results obtained in the previous ship or ships. The article also reports on the performance of the system in the Hampton Maru in her first twelve months' service, during which the cooling-water flow decreased because of hull fouling.
