摘 要
本文阐述了6000T近海成品油船的设计。
内容包括任务书分析，主要要素的确定，船体型线设计，船舶性能计算，总布置设计，舱容和各种载况下的稳性计算，阻力计算，螺旋桨和舵设计等。整个设计过程以货舱舱容、稳性、操纵性和经济性为中心。确保设计的船具有足够的舱容，改善设计船的稳性和操纵性，同时具备良好的经济性。
设计船的主要数据如下：总长Loa=108.3m,两柱间长Lpp=103m,设计水线长Lwl= 105.33m, 型宽B=17m,型深D=7.9m,吃水T=6.4m,排水量Δ=8415t , 浮心纵向位置Xb= 0.538m(舯前)，方形系数Cb=0.73，棱形系数Cp=0.738，舯剖面系数Cm=0.989，水线面系数Cw=0.850，货舱容积VC=8281.409m3。
