The invention relates to the technical field of ship construction, and discloses an LNG (Liquefied Natural Gas) ship NO96 type containment system mounting platform integral hoisting method which comprises the following steps: S1, mounting a hoisting structure on a bottom layer part of a mounting platform; s2, a distance keeping structure is installed on the top layer part of the installation platform; and S3, a sling hung by a lifting hook of the crane is connected with a lifting ring above the supporting rod. The lifting points are arranged on the high-strength bottom-layer part, the lifting strength is ensured, the problem that the distance between the lifting hooks is not matched with the distance between the lifting points on the bottom layer of the mounting platform is solved through the supporting rods, the vertical state of the slings below the supporting rods is kept through the distance keeping structure on the top layer, the overturning risk of the lifting points below the gravity center is avoided, and the lifting safety is improved. The hoisting stability is ensured, the problem that the mounting platform is disassembled into small modules for hoisting due to the limitation of hoisting strength in the conventional hoisting method is solved, the integral hoisting of the mounting platform is realized, and the construction efficiency is greatly improved.
本发明涉及船舶建造技术领域,且公开了一种LNG船NO96型围护系统安装平台整体吊装方法,包括如下步骤:S1.在安装平台底层零件上安装吊装结构;S2.在安装平台顶层零件上安装保距结构;S3.吊机的吊钩所挂吊索与撑杆上方的吊环相连接。本发明通过将吊点布置在了强度较高的底层零件上,确保了吊装强度,通过撑杆,解决了吊钩间距与安装平台底层吊点间距不匹配的问题,通过顶层的保距结构,保持了撑杆以下吊索的竖直状态,避免了吊点在重心以下的倾覆风险,确保了吊装稳定性,解决了以往吊装方法中因吊装强度限制而将安装平台拆为小模块吊装的问题,实现了安装平台的整体吊装,大幅度提高了施工效率。
