The invention discloses a subsection division method for a cargo hold area of a thin film type LNG (Liquefied Natural Gas) ship. The subsection division method comprises the following steps of: 1), dividing all key nodes W1-W5 on the inner shell wall of a cargo hold into segments; 2), arranging a large joint between the two cargo compartment areas in a transverse compartment; 3), dividing each transverse compartment independently; and 4), dividing a liquid dome area into independent sections. The subsection division method is more scientific and reasonable, greatly reduces labor intensity, is good in implementation effect, the cargo space building precision of a cargo space area and structural centering precision of key nodes can be guaranteed and the method has the advantages of reducing dock carrying and hoisting, reducing assembling and welding workload of dock large joints and paint damage amount; dock and wharf fitting-out work forward movement is achieved to the maximum extent, ship launching integrity is improved, and the dock period is further shortened.
本发明公开了一种薄膜型LNG船货舱区分段划分方法,该方法包括以下步骤:1)将货舱内壳壁上的关键节点W1~W5全部划在分段内;2)将两个货舱区之间的大接缝布置在横隔舱;3)每座横隔舱均采用独立划分;4)液穹区域划为独立分段。本发明的分段划分方法更为科学合理、大大降低了劳动强度、实施效果良好,不仅保证了货舱区舱容建造精度和关键节点的结构对中精度,也具有减少船坞搭载吊装,减少船坞大接缝的装焊工作量、油漆破损量,最大化的实现船坞和码头舾装工作前移,提高船舶下水完整性,使船坞周期得以进一步缩短。
