Abstract

The invention provides a mounting process for a thruster. The mounting process comprises the following steps: I, finding a vertical center line of the thruster on a ship body; II, finding a mounting hole of the thruster on the ship body; III, finding a horizontal input shaft center line of the thruster on the ship body; IV, confirming the plane degree accuracy of the ship body; V, hoisting the thruster, and confirming the plane degree once again. The mounting process for the thruster has the advantage of convenience in mounting and implementation; the deformation condition of the ship body is confirmed before final mounting, so that mounting of the thruster is effectively ensured, and the production period is greatly shortened.

Description

technical field [0001] The invention relates to an installation process of an LNG liquefied gas ship, in particular to an installation process of an azimuth thruster. Background technique [0002] LNG (liquefied natural gas) carriers play an important role in current water transportation, and they need to integrate various advanced technologies. At present, the most advanced LNG carriers in my country use azimuth propellers as power output. [0003] Combined with the ship model test and calculation results, there are two main requirements for the installation of azimuth propellers on ships: [0004] 1. One-degree angle requirements on the vertical plane; [0005] 2. Two-degree angle requirements on the horizontal plane; [0006] Due to the small value of the angle, the requirements for hull manufacturing accuracy, full-turn installation accuracy, and welding deformation accuracy are relatively high. According to market research, except for some small boats without requirem...
