Problems solved by technology

[0003] With this installation method, it takes a long time to assemble and weld for the installation of the fairing and stern tube
In addition, during the installation process of the fairing and stern tube, it is necessary to work at high altitude, so the lifting difficulty and construction risk are high
In addition, after the installation of the fairing and stern tube, a tightness test is required, which prolongs the installation period

Abstract

The invention discloses a guide cover and stern tube installation method. The method comprises the following steps: S100, erecting a support bar and a benchmark bar on a ground sample according to therequirements of a design drawing; S200, hoisting and positioning the stern tube on the support bar; S300, hoisting and installing the guide cover on the position corresponding to the stern tube and positioning the guide cover; S400, welding and fixing the guide cover and the stern tube. The assembly process of the guide cover and the stern tube is moved to the ground stage, the amount of high-altitude work of the stern system installation can be reduced, the hoisting difficulty of the guide cover and the stern tube assembly can be effectively reduced, the total assembly time of the ship can be shortened, and the dock occupation period of the ship can be reduced.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for installing a fairing and a stern tube. Background technique [0002] During the construction of existing ships, for ships containing fairings and stern tubes, it is necessary to pull the shafting of the ship at the dock stage to determine the installation position of the shafting of the ship, and then adjust the installation of the shaft bracket of the ship position, then install the lower part of the front fairing and the rear fairing in sequence, then insert the stern tube and install the upper part of the rear fairing. [0003] With this installation method, the installation of the spinner and stern tube requires a long time for assembly and welding. In addition, during the installation process of the fairing and stern tube, it is necessary to work at high altitude, which makes the lifting difficult and the construction risk is high. In addition, a tightne...
