The invention relates to a method for installing vent pipe unit modules around a vent mast of an LNG (Liquefied Natural Gas) ship, which comprises the following steps of: arranging vent pipes around the vent mast, and integrating to form an L-shaped pipe system set; a combined support is arranged on the L-shaped pipe system set to form a vent pipe unit module; vent pipe unit modules are processed and manufactured, and hanging rings are arranged; the vent pipe unit modules are integrally hoisted on a ship at the wharf stage; and installation of the vent pipe unit module is completed. According to the installation method of the ventilation pipe unit module around the LNG ship ventilation mast, the ventilation pipes around the ventilation mast become an integral unit module through the combined support, positioning, welding and installation work of most pipe sections and accessories is completed in the unit module stage, the safety risk caused by high-altitude operation is reduced, and the installation efficiency is improved. Wharf crane resources are saved, the construction efficiency is further improved, and the construction period of the LNG ship is effectively shortened.

    本发明涉及一种LNG船透气桅周围的透气管单元模块的安装方法,包括以下步骤:对透气桅周围的透气管进行布置,整合形成“L”型管系合集;在“L”型管系合集上设置组合支架以形成透气管单元模块;对透气管单元模块进行加工制作并布置吊环;将透气管单元模块在码头阶段整体吊装上船;完成透气管单元模块的安装。本发明的一种LNG船透气桅周围的透气管单元模块的安装方法,通过组合支架使透气桅周围的透气管成为一个整体的单元模块,让大部分管段及附件的定位、焊接、安装工作在单元模块阶段完成,降低高空作业所带来的安全风险,节约了码头吊车资源,进一步提高了建造效率,有效地缩减了LNG船的建造周期。
