Abstract

The invention discloses a manufacturing method of a dome deck panel of an LNG (liquefied natural gas) ship. The method specifically comprises the following steps: manufacturing a ribbed plate small assembly and a longitudinal small assembly; manufacturing a trunk deck middle assembly; manufacturing an external inclined top plate middle assembly; manufacturing a main deck middle assembly; manufacturing an internal inclined top plate middle assembly; combining the trunk deck middle assembly, the external inclined top plate middle assembly, the main deck middle assembly and the internal inclinedtop plate middle assembly to assemble the dome deck panel. According to the method, the dome deck panel is split into the multiple assemblies, the working face is comprehensively and effectively unfolded, so that the construction efficiency is effectively increased, the construction cycle is shortened, and the building efficiency of the ships is increased.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a segmented manufacturing method for an LNG ship dome deck. Background technique [0002] LNG carrier is a product of "three highs" with high technology, high difficulty and high added value. LNG carrier is the jewel in the crown of shipbuilding. Among the many types of sections of LNG ships, the dome section is a relatively complex section in the liquid cargo tank area of ​​LNG ships. The traditional manufacturing method based on manual assembly and welding has the following shortcomings: [0003] First, the segmented dome manufacturing cycle is long and the production efficiency is low. At present, the dome segments, which are mainly assembled and welded by hand, adopt the serial integral construction method. This method does not divide the dome segments into rib plate sub-units, longitudinal sub-units, and trunk deck sub-units according to the requirements of the process...
