对600-5000DWT油船结构型式的探讨

An Investigation on Structural Type of Cargo Tank for 600-5000 DWT Tanker

MARPOL 73/78的13F新规则对6OO-5000DWT油船提出了采用双层底的结构型式,并限制每个货油舱容积不大于700m^3。本文建议作为等效措施可选用双舷的结构型式.对3000-5000DWT油船最大货油舱容积可放大到1000m^3,有利于设计建造这一类油船。本文还探讨了此类油船的主尺度、稳性,以供设计参考。

The new regulation 13F of Annex I to MARPOL 73/78 present that double bottom cargo tank or space is required for 600-5000 DWT tanker and the capacity of each cargo tank does not exceed 700M3. This paper suggests that the double wing 600-5000 DWT tanker, and the capacity of each cargo tank can be increased up to 1000M3, thus facilitating the design and construction of this type of tankers. The principal dimensions and stability are also discussed in the paper.
