Background
The heat-insulating layer of the gas transport ship is arranged on the main hull structure outside the liquid tank. According to the construction process, the insulation needs to be installed after the strength test of the ballast tank is finished. It is now common practice to conduct a ballast tank strength test at the dock stage after the ballast tank structure is completed, by flooding the ballast tank at the dock stage to complete the strength test. This results in the gas carrier insulation needing to be installed at the dock stage. Because the construction period of the heat insulation layer of the gas carrier is long, if the insulation is installed in the dock stage, a large number of dock periods are occupied. It is known that dock efficiency is a key factor affecting shipbuilding efficiency in shipyards, and dock resources are bottleneck resources of a shipyard. In order to shorten the dock period and realize quick construction, the strength test and insulation installation stages need to be moved forward to the total stage.

normally placing the broadside block structure after the broadside block structure is finished, and plugging an opening on a bottom longitudinal girder of the broadside block;
placing the port and starboard side sections face to face, and placing the port and starboard side sections on a strength test service rack for a first strength test;
after the first strength test is finished, installing a heat-insulating layer on the side state broadside block;
plugging an opening on a bottom longitudinal girder of the double-bottom-layer block;
after the preparation work is finished, water injection is started, and a second strength test is finished;
and a heat-insulating layer is arranged on the double-bottom-layer main section.
Preferably, the first strength test refers to: and arranging a vent pipe at the highest point of the top of the broadside block, and starting water injection after the preparation work is finished to finish the strength test.
Preferably, after the first strength test is qualified, draining the water in the ballast tank, and dismantling the corresponding tool; placing the broadside block in a wind and rain shed in a lateral state by taking the outer plate as a base surface; and after the installation and the inspection of the heat preservation layer are finished, hoisting the main section to a dock for carrying.
Preferably, after the second strength test is qualified, draining the water in the ballast tank, and dismantling the corresponding tool; placing the double-bottom-layer general section in a wind and rain shed; and after the installation and the inspection of the heat preservation layer are finished, hoisting the double-bottom-layer block section to a dock for carrying.
The invention has the beneficial effects that: according to the invention, the total section of the cargo compartment ring section is divided into the left and right side total sections, the double-bottom total section at the bottom and the deck total section, so that the strength test of the ballast compartment of the gas transport ship and the insulating installation of the ballast compartment in the total section are realized, the dock period is greatly shortened, and the efficient construction is realized. In addition, in the process, the open holes are plugged, so that the ballast tank is watertight.
