Abstract

The invention discloses a positioning method for a single-shell fuel tank block. The positioning method comprises the following steps that S1, a guide sliding block is installed on a fuel tank beforethe fuel tank is hoisted; S2, the relative position of the guide sliding block on the fuel tank is determined; S3, according to the relative positions, corresponding sliding block bases are installedon the double-layer bottom of a ship body; S4, the fuel tank is hoisted in place, the position of the fuel tank is adjusted, and a folding line on the guide sliding block is aligned with the folding line on the corresponding sliding block bases; and S5, assembling and welding are performed after the fuel tank is positioned. The positioning sliding block is adopted for positioning, the tool is simple and convenient, operation is easy, and on-site construction is facilitated.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a positioning method for the general section of a single-hull fuel tank in a fuel tank modification project. Background technique [0002] Due to its weak structure, the general section of the single-hull fuel tank is easily deformed during hoisting and positioning. Therefore, it is necessary to find a fast positioning method to reduce the risk during the positioning of the general section of the fuel tank. For the large general section / ring section, the commonly used positioning methods are: 1. Use multiple synchronous jacking devices for the displacement and positioning of the general section; 2. Use large lifting equipment for the general section hoisting, and use a three-dimensional total station for positioning to locate. However, when the general section of the single-hull fuel tank has a weak lower opening structure and needs to be hoisted into the tank, ...
