Intelligent manufacturing method for LNG ship double-layer bottom subsections

Abstract

The invention discloses an intelligent manufacturing method for LNG ship double-layer bottom subsections. The method specifically comprises the following steps: manufacturing an inner bottom plate middle assemblage, an outer plate secondary middle assemblage, a second longitudinal girder small assemblage, a first rib plate small assemblage, a third longitudinal girder small assemblage, a simple small assemblage, a second rib plate small assemblage and a longitudinal girder combined small assemblage; assembling the second rib plate small assemblage and the third longitudinal girder small assemblage together to generate a first longitudinal girder small assemblage; arranging a first small longitudinal girder assembly, a second small longitudinal girder assembly, a first small rib plate assembly, a simple small assembly and a small longitudinal girder assembly on the secondary middle assembly of the outer plate to form a middle assembly of the outer bottom plate; and folding the outer bottom plate middle assemblage and the inner bottom plate middle assemblage into a double-layer bottom subsection. According to the method, all intermediate products can be effectively managed, the turnover rate of a site can be increased, product overstock is reduced, and the construction quality and the construction efficiency of the double-layer bottom subsection are guaranteed.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an intelligent manufacturing method for double-bottom segments of an LNG ship. Background technique [0002] LNG ship is a high-tech, high-difficulty, and high-value-added "three-high" product. With the rapid development of the shipbuilding industry, my country has entered the main battlefield of direct competition with Japanese and Korean shipbuilding companies in the field of LNG ship construction. However, compared with Japanese and South Korean companies, there is still a relatively large gap in the construction quality and construction efficiency of my country's LNG ships. As the country proposes the strategy of intelligent manufacturing, the implementation of intelligent shipbuilding in the shipbuilding industry has become a necessary means for the high-quality and efficient development of my country's shipbuilding industry and the implementation of corner overtaking fo...
