Abstract

The invention discloses an installation precision control method of a C-shaped saddle of an LNG filling ship. The installation precision control method comprises the steps of manufacturing the C-shaped saddle and installing the C-shaped saddle. C-shaped saddle manufacturing comprises the following steps of S11, a precision design of the C-shaped saddle; S12, C-shaped saddle manufacturing; S13, datum line drawing; S14, precision detection; and S15, C-shaped saddle transportation. C-shaped saddle installation comprises the following steps of S21, C-shaped saddle arc center point determination; S22, datum line reinspection; S23, C-shaped saddle positioning; and S24, C-shaped saddle installation. The manufacturing precision and the installation precision of the C-shaped saddle are monitored inthe whole process in the manufacturing and installation stages so that an actual mounting position of the liquid tank in the cargo hold is adjusted, the liquid tank is supported and fixed, stabilityof a liquid tank installation system is improved, and operation safety of the LNG filling ship is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a method for controlling the installation accuracy of a C-shaped saddle of an LNG filling ship. Background technique [0002] As a clean energy source, LNG has obvious advantages in energy saving and emission reduction, especially in the emission reduction of sulfide and nitride, and has attracted more and more attention from the shipping industry. With a large number of LNG-powered ships put into use, the market for LNG bunkering ships has emerged as the times require. [0003] LNG bunkering ships store high-pressure natural gas through large liquid tanks. In order to meet the requirements of economy, the length of the liquid tank exceeds 34 meters, and the diameter of the liquid tank reaches 13 meters. If such a large-sized liquid tank is not installed in place during the installation stage, problems such as uneven stress on the tank body, large internal disp...
