摘　　要：本文以 2 8 0 0 0 m3L PG船为研究对象 ,对其首端线型作优化改型 ,优化所得线型在 3种装载状态下获得平均降低功耗 5 .5 8%的效果 ,满载设计航速比设计指标 16 kn提高 0 .38kn。乙烯装载状态和压载状态的功耗降低幅度更大 ,航速提高更多 ,其装载量、经济性和实船性能明显优于同类型的 16 5 0 0 m3和 2 2 0 0 0 m3L PG船。With a 28 000 m 3 LPG taken as a study object, the paper presents how lines optimization is done to its fore body. It is found the new lines obtained 5.85% average power saving effect at all three loading conditions, with design speed at full load increased by 0.38 kn from the 16 kn required speed. It is found that at ethylene loading condition and ballast condition the reduction of power consumption and the increase of the speed are greater than these values. The loading capacity, cost effectiveness and ship running performance are much better than those of similar ships such as the 16 500 m 3 and 22 000 m 3 LPG carriers.
