Construction method of chemical ship pipe collecting area unit

Abstract

The invention relates to a construction method of a chemical ship pipe collecting area unit, which comprises two layers of brackets, two layers of pipelines and a platform, wherein a bottom layer of brackets, a bottom layer of pipelines, an upper layer of brackets, an upper layer of pipelines and the platform are respectively arranged from bottom to top, the construction method comprises the following steps of: constructing a pipe collecting area unit on a special bracket; arranging a column type jig which simulates the height of T rows of main decks of the pipe collecting area on the specialbracket as a bracket for supporting the pipe collecting area unit; and placing the special bracket on a unit construction site, after the construction of the pipe collecting area unit is finished, transporting the special bracket to a dock or a berth area through a flat car under the condition of not taking off the tire, so that the pipe collecting area unit is directly hoisted on the ship. According to the method, the hoisting of the whole unit is avoided, the limitation of hoisting capacity is avoided, the integrity of the unit is greatly improved while the whole weight of the unit is improved, and the deformation of the unit from the hoisting belt is effectively avoided.

Description

technical field [0001] The invention relates to ship building, in particular to a method for building a header area unit of a chemical tanker. Background technique [0002] A chemical tanker refers to a ship specialized in transporting chemicals. One of the characteristics of a chemical tanker is that the T row and longitudinal members of the main deck in the cargo hold area are located above the main deck. The header area unit is an important structural component. The header area unit It refers to a comprehensive unit formed by outfitting parts such as pipelines, brackets, and platforms in the header area located in the middle of the cargo hold area. One of its characteristics is that the brackets will be supported on the T row of the main deck of the header area, and the height of the lower ends of the columns is inconsistent. With such as figure 1 As shown, the header area unit is composed of two layers of supports, two layers of pipelines, and a layer of platform. From ...

AI Technical Summary

Problems solved by technology

[0006] First, the fetal position needs to be fixed, which is not convenient for the turnover of the site, resulting in a certain waste of site resources

[0007] Second, limited by the lifting capacity of the unit construction site, the header area units need to be built in layers, and the degree of integrity is not high, leaving more work on board

[0008] Third, it is necessary to hoist the upper mast at the unit construction site, which is likely to cause deformation of the unit and increase subsequent repair work

[0009] Fourth, when the unit is placed on the door frame, it is necessary to install a temporary column without decoupling, which involves a large workload and poses a safety hazard

[0010] Fifth, the cantilevered transportation will easily cause the deformation of the unit and increase the follow-up correction work
