Abstract

The invention relates to the technical field of ships, in particular to a drill floor BOP hanging beam assembling method. The drill floor BOP hanging beam assembling method comprises the following steps of modeling, material feeding and assembling, wherein the modeling step comprises the step that during structural modeling, shrinkage amounts of preset sizes are added to a first panel, a second panel, a first web plate and a second web plate in the length direction; the material feeding step comprises the steps that in the material feeding process, the straightness of the first panel, the straightness of the second panel, the straightness of the first web plate and the straightness of the second web plate are checked and corrected; in the assembling process, an even number of welders are adopted for left-right symmetrical welding; in the assembling process and after assembling is completed, straightness, flatness, perpendicularity and the like are detected; and correction is conducted in time when out-of-tolerance is found. Therefore, according to the drill floor BOP hanging beam assembling method, errors are eliminated from the aspects of design, material feeding, assembly and the like, and then the precision requirements such as the size, the straightness and the levelness of the hanging beam are guaranteed, reworking operation caused by insufficient precision is avoided, and therefore, a large amount of working hours and energy consumption are saved, and the operation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of ships, in particular to a method for assembling a drilling rig BOP suspension beam. Background technique [0002] At present, the blowout preventer crane (BOP crane) is mainly used to lift the blowout preventer, and handle the casing with casing claws, and the BOP crane beam is used as the track for the BOP crane to travel. The overall accuracy of the BOP hanging beam is relatively high, as follows: [0003] (1) The levelness of the bottom panel of the single side track is within ±2mm; [0004] (2) The straightness of the track on one side is ±1mm every 2000mm; [0005] (3) Height deviation requirement between two tracks: ±3mm; [0006] (4) Width deviation requirement between two tracks: ±2mm; [0007] It can be seen that the overall precision of the hanging beam is relatively high, but in actual production at present, the precision control and construction are difficult.
