Abstract
Various kinds of ship are operated to transport cargo or passengers at sea in the world. Most of the important auxiliary machineries installed in those ships are fluid machineries such as pumps, compressors, and fans. A large percentage of fluid machinery is pumps which are classified turbo and positive displacement pumps. This paper analyzes only positive displacement pumps. This thesis has two aims: (a) to analyze the present status of pumps installed in merchant and training ships and (b) to find the correlation among sea going pump ㎾, port pump ㎾, total pump kW, GE ㎾, ME MCR, number of pumps, ME kgf, pump kgf. Based on ship's type, this paper seeks to find special characteristics as a result of analyzing head, flow rate, and ㎾. Moreover this paper analyzes and compares number of pumps, pump kW/ME MCR, pump ㎾/GE ㎾ under the conditions of seagoing and berthing according to ship's type.
