CSR对超大型油船装载及压载舱分舱的影响

CSR efforts on loading conditions and arrangement of ballast tanks of very large crude oil carrier

国际、国内的油运市场对超大型油船(VLCC)的需求非常迫切。油船结构共同规范(CSR)不仅对VLCC结构设计的影响是全面和系统的,还对VLCC的装载工况和压载舱分舱方案有很大的影响,而这些因素直接决定了船体的最大中拱静水弯矩。该文针对30.8万吨VLCC,对CSR进行了研究,通过装载计算,初步阐明了CSR对VLCC装载工况和压载舱分舱设计的影响。

Nowadays there is a big demand on VLCC and will increase steadily. Common Structural Rules for Double Hull Oil Tankers （CSR） have great influence not only on structural design of VLCC, but also on loading conditions and arrangement of water ballast tanks which directly determines the value of maximum bogging still water bending moment of ship hull. In this paper, a 308 000 DWT VLCC is used to consider the CSR effect, and its influence on loading conditions and arrangement of water ballast tanks are discussed by loading calculation.
