The invention provides a VLCC cargo oil tank segmentation and carrying process, which is characterized in that a VLCC cargo oil tank is divided into a plurality of segments in the length direction; the segments comprise an upper deck, a longitudinal bulkhead and a middle structure segment; the upper deck is divided into a DCS segment and a DCP segment along the symmetry plane; the longitudinal bulkhead is divided into an LAP segment and an LAS segment along the symmetry plane; and the middle structure segment is located between the two segments of the longitudinal bulkhead, the middle structure segment is of a cross beam structure or a sealed transverse bulkhead, and then carrying is conducted according to the segments. The invention belongs to the technical field of cargo oil tank segmentation and carrying, and the original LB segment deck small group and large group integration operation is omitted; and no turning-over fortification exists in a fixed disc in the dock, external field operation is turned into internal field operation, the operation procedure is advanced, the construction time of the in-dock operation is shortened, and the dock period is shortened.

    本发明提供VLCC中货油舱分段分割及搭载工艺,将VLCC中货油舱沿长度方向分成若干组节段:所述节段包括:上甲板、纵舱壁、中间结构分段:将上甲板沿对称面分成DCS、DCP两个分段;将纵舱壁沿对称面分成LAP、LAS两个分段;所述中间结构分段位于纵舱壁的两个分段之间,所述中间结构分段为横梁结构或密性横舱壁,然后按照上述分段进行搭载,属于货油舱分段和搭载技术领域,本工艺取消原LB分段甲板小组,大组一体化作业;坞内定盘无翻身工事,外场作业内场化,使作业工序前道化,减少了坞内作业施工工时,缩短了坞期。
