The invention discloses a ship liquid cargo tank sub-layer loop line establishing method, which comprises the following steps of: 1, measuring the length of each edge line and the length of a diagonal line of a cargo tank surface, and determining the distribution of 10 tank wall surfaces of a liquid cargo tank; 2, calculating and marking actual midpoint position information of the edge line according to the length of the edge line; 3, actual midpoint position information of the edge line and a cargo hold theoretical value are input into design software for calculation, the actual position of a cargo hold datum line is calculated according to the deviation value of an actual midpoint and a theoretical midpoint, and the cargo hold datum line comprises a cargo hold transverse datum line and a cargo hold longitudinal datum line; and 4, marking out cargo hold datum lines of the bulkheads, and connecting the transverse datum lines and the longitudinal datum lines of the bulkheads to form rings in three directions, namely a horizontal ring, a longitudinal ring and a transverse ring. According to the method, the measurement difficulty of the MarkIII type enclosure system is reduced, and a foundation is laid for the subsequent construction of the MarkIII type enclosure system.

    本发明公开了一种船舶液货舱次层环线建立方法,包括以下步骤:步骤一、对货舱面的各个边缘线的长度及对角线的长度进行测量,确定液货舱10个舱壁面的分布;步骤二、根据边缘线的长度计算边缘线的实际中点位置信息并标记;步骤三、将边缘线的实际中点位置信息与货舱理论值输入到设计软件中进行计算,根据实际中点与理论中点的偏移值计算货舱基准线的实际位置,货舱基准线包括货舱横向基准线与货舱纵向基准线;步骤四、划出各舱壁的货舱基准线,将各舱壁的横向基准线、纵向基准线连接起来,即组成3个方向的环:水平方向环、纵向方向环、横向方向环。本发明降低了MarkIII型围护系统的测量难度,为后续MarkIII型围护系统的建造打下了基础。
