Ship engine room position segment division method

Abstract

The invention discloses a ship engine room position segment division method. During the segmentation construction of the engine room of the ship, wall plates connecting the bottom section and the upper section of an outfitting area of an engine room basin are divided into upper wall plates and lower wall plates according to the dividing position lines, the upper wall plates are constructed with the upper segment, the lower wall plates are constructed with the bottom segment; the upper wall plates are butt-jointed with the lower wall plates in a stage where the upper and bottom segments are folded together; corner joining of the wall plates in the narrow space can be avoided after the outfitting is installed in the engine room, the problems of narrow construction space of the hull operation, poor construction environment, potential safety hazards, and influence of water accumulation and other factors can be solved, and the on-site production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for segmenting the position of a ship engine room. Background technique [0002] The upper section of the ship's engine room basin outfitting area includes decks, shell plates, longitudinal and transverse bulkheads and other structural members. The longitudinal and transverse bulkheads are usually completely divided into the upper section. When the sections are closed, the longitudinal and transverse bulkheads of the upper section are connected to the deck of the bottom section by fillet welding. This division method has the following problems: [0003] 1. The siding of the upper section usually corresponds to the structure on the opposite side of the deck, and the corner joint form greatly increases the risk of structural dislocation during the large closing operation; [0004] 2. The fillet welding operation on the deck surface of the bottom section of the outf...

AI Technical Summary

Problems solved by technology

[0003] 1. The siding of the upper section usually corresponds to the structure on the opposite side of the deck, and the angle joint form greatly increases the risk of structural dislocation during the large closing operation;

[0004] 2. The fillet welding operation on the deck surface of the bottom section of the outfitting of the engine room basin is easily affected by the surrounding environmental factors, especially for the section of the outfitting area of ​​the bottom basin of the engine room, where a large number of pipe units and equipment are arranged on the deck surface of the bottom section Outfittings such as seat frames and walking bridges, after the upper layer is hoisted in sections, the connection between some wall panels and the deck of the bottom section is "surrounded" by unit frames and pipes, the construction space of the hull is narrow, the construction environment is poor, and there are great safety hazards , and are susceptible to deck area water;

[0005] 3. The working area of ​​personnel in some construction areas is narrow, and it is necessary for the outfitting unit to remove some of the outfitting parts before the construction can be carried out safely. This greatly increases the workload of the outfitting unit, and at the same time, due to the coordinated operation across units, it will also affect the construction of each unit cycle;

[0006] 4. Cross-operation between outfitting and hull increases safety risks
