Installation method for cabins and side walls of cargo tanks

Abstract

The invention discloses an installation method for cabins and side walls of cargo tanks. The method comprises the steps that cargo tank supporting bases are installed at the preset fixing positions of the outer side walls of the cargo tanks, and cabin supporting bases are correspondingly installed at the preset fixing positions of the inner side walls of the cabins; actual coordinates of each cargo tank supporting base and the corresponding cabin supporting base; according to the differences between theoretical coordinates and the actual coordinates of the carbon tank supporting bases and the differences between the theoretical coordinates and the actual coordinates of the corresponding cabin supporting bases, the thickness and the installation positions of base plates are obtained; according to the obtained thickness of each base plate, the base plates are manufactured, and according to the installation positions of the base plates, the manufactured base plates are installed on the cargo tank supporting bases or the cabin supporting bases; each cargo tank is suspended into the preset installation positions inside the cabin. It is ensured that the supporting bases on the side walls of the cargo tanks and the supporting bases on the cabins can be effectively assembled, and therefore normal installation of the cargo tanks and the cabins can be ensured.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for installing a side wall of a cargo tank and a cabin. Background technique [0002] The asphalt ship is a new type of ship. Because there is an independent cargo tank structure inside, the support form of the tank itself and the hull cargo warehouse itself is particularly important. As the line shape of the hull shrinks from the parallel middle body to the fore and aft direction respectively, the outer dimensions of the cargo tanks located in the fore and aft areas of the hull will become more and more tightened, and multiple support seat structures will be designed in the fore and aft areas for the hull to align the cargo tanks. The upper and lower support of the side wall. [0003] Due to the characteristics of the ship type, the number of support seats is large and dense. If the support seats on the cargo tanks are installed according to the theoretical data o...

Problems solved by technology

[0003] Due to the characteristics of the ship type, the number of support seats is large and dense. If the support seats on the cargo tanks are installed according to the theoretical data of the drawings in the traditional method (that is, the coordinate positions and dimensions of the support seats of each cargo tank are set on the drawings Size), so that when the cargo tank is hoisted into the cabin later, the support seat on the cargo tank and the support seat on the hull bulkhead below will be misaligned, and the position error between the two will easily exceed the tolerance range required by the drawing. As a result, the support seat on the cargo tank and the support seat on the hull bulkhead cannot be effectively assembled, thereby affecting the normal installation of the cargo tank and the cabin
