The invention discloses a marking method for a Mark3 type LNG ship reference axis. The marking method comprises the steps that the internal size of a liquid cargo tank is measured; the actual midpoint position of an edge line is marked; a deviation value between a reference line and an actual midpoint is calculated; datum lines BR1 and BR2 of each bulkhead are drawn; and the perpendicularity of the datum line BR1 and the datum line BR2 is checked. According to the marking method for Mark3 type LNG ship reference axis, the datum line of each surface is accurately marked and the datum line of each surface forms a ring. 本发明公开了一种用于Mark3型LNG船基准轴线划线方法，所述方法包括：测量液货舱内部尺寸；标注边缘线实际中点位置；计算出基准线距离实际中点的偏移值；划各舱壁基准线BR1、BR2线；检查基准线BR1、BR2线的垂直度。本发明准确划出各面的基准线并使各面基准线成环。
