The invention relates to a segmented construction method for double tail fins of an LNG ship, which comprises the following steps: dividing a single tail fin into a stern shaft small section and a stern cusp cabin small section, respectively constructing and closing the stern shaft small section and the stern cusp cabin small section, and the stern shaft small section comprises a stern shaft tube,an outer plate close to one side of a midship and an outer plate close to one side of a board; each stern cusp small segment comprises a platform plate, a longitudinal component and a stern cusp small segment outer plate. By means of the construction method, the segmented construction precision can be effectively controlled, the follow-up propeller installation precision is ensured, and the segmented construction quality of the double tail fins of the LNG ship is improved.

    本发明涉及一种LNG船双尾鳍分段建造方法,该方法将单只尾鳍分段划分为艉轴小片段和艉尖舱小片段,艉轴小片段和艉尖舱小片段分别建造后合拢,艉轴小片段包括艉轴管、靠近船舯一侧的外板、靠近舷侧一侧的外板,艉尖舱小片段包括平台板、纵向构件、艉尖舱小片段外板。通过本发明的建造方法,可有效控制分段建造精度,确保后续螺旋桨安装精度,提升LNG船双尾鳍分段建造质量。
