The invention provides a simulation hoisting control method for a ship LNG large storage tank. The simulation hoisting control method comprises the following steps that S1, a small saddle assembly is manufactured; s2, saddle carrying line type simulation positioning, specifically comprising the following steps: S21, scanning data of a molded outer edge laminated wood line type of the LNG large-scale storage tank by adopting a three-dimensional scanner, and performing data analysis on the scanned laminated wood line type; s22, the saddles are assembled and positioned, the seven small assemblies of the fixed saddles are assembled into a fixed annular saddle, the seven small assemblies of the sliding saddles are assembled into a sliding annular saddle, and size precision control is conducted in the saddle positioning process in the assembling process; s23, saddle assemblies are welded and formed, and the seven small assemblies of the fixed saddle and the seven small assemblies of the sliding saddle are welded respectively; s24, the saddle line type is matched with the LNG tank body laminated wood in a simulation mode; and S3, the LNG large storage tank is hoisted. The epoxy clearance fitting degree of the saddle and the tank body laminated wood is ensured through three-dimensional scanning simulation and accurate process control, and the large storage tank is hoisted in place at a time.
本发明提供了一种船舶LNG大型储罐的模拟吊装控制方法,包括以下步骤:S1.鞍座小组立制作;S2.鞍座搭载线型模拟定位,具体包括以下步骤:S21.采用三维扫描仪对已成型的LNG大型储罐的外缘层压木线型数据进行扫描,并对扫描后的层压木线型进行数据分析;S22.鞍座组装定位,固定鞍座的七块小组立组装成固定环形鞍座、滑动鞍座的七块小组立组装成滑动环形鞍座,在组装过程对鞍座定位过程进行尺寸精度控制;S23.鞍座组立焊接成型,分别焊接固定鞍座的七块小组立和滑动鞍座的七块小组立;S24.将上述鞍座线型与LNG罐体层压木模拟匹配;S3.LNG大型储罐吊装。本发明通过三维扫描模拟以及过程精准控制确保鞍座与罐体层压木的环氧间隙贴合度,实现大型储罐吊装一次到位。
