Overall manufacturing process for anchor platform of drilling ship and structure of anchor platform

Abstract

The invention discloses an overall manufacturing process for an anchor platform of a drilling ship. The process includes: step A, manufacturing an assembly jig, and marking a center line of the assembly jig and an assembly line of a structure of the anchor platform on the assembly jig ; step B, marking a center line and an assembly positioning base line of a hawse pipe on a prefabricated hawse pipe; step C, assembling the hawse pipe on temporary tools, and calculating an included angle between the hawse pipe and a shell plating of a ship body; and step D, setting a structure base point on the hawse pipe, and assembling a shell plating of the anchor platform and an anchor mouth. Through the overall manufacturing process for the anchor platform of the drilling ship and a structure of the anchor platform, working environment of manufacturing and assembling the anchor platform is greatly improved, assembling and welding of the structure of the anchor platform are benefited, working aloft is reduced, personal safety is benefited, production efficiency and welding quality are improved, and production cycle is shortened.

Description

technical field [0001] The invention relates to an overall manufacturing process of a drilling ship anchor platform. Background technique [0002] In the prior art, due to the special shape of the anchor platform, narrow internal space, dense structure, large amount of welding, harsh construction environment, and difficult to guarantee the welding quality, in order to improve the working environment and meet the installation requirements, the structure was used to ship in bulk The traditional process of installation, the specific method is: firstly, install the anchor chain pipe on the section and extend out of the hull plate, leaving a cutting allowance at the pipe end; secondly, install two parts of the internal structure of the anchor platform, one part in bulk. The other part is installed on the anchor chain pipe protruding from the outer plate of the hull; finally, the inner structure of the outer plate of the anchor platform is aligned with the anchor chain pipe and th...

[0002] In the prior art, due to the special shape of the anchor platform, narrow internal space, dense structure, large amount of welding, harsh construction environment, and difficult to guarantee the welding quality, in order to improve the working environment and meet the installation requirements, the structure was used to ship in bulk The traditional process of installation, the specific method is: firstly, install the anchor chain pipe on the section and extend out of the hull plate, leaving a cutting allowance at the pipe end; secondly, install two parts of the internal structure of the anchor platform, one part in bulk. The other part is installed on the anchor chain pipe protruding from the outer plate of the hull; finally, the inner structure of the outer plate of the anchor platform is aligned with the anchor chain pipe and then installed and welded; the whole installation process is based on the anchor platform It is independent from the anchor chain pipe and the structure is mainly in bulk, resulting in low production efficiency; and the construction is carried out at high altitude, which is not conducive to personal safety; some structures form a narrow space, which is not conducive to the improvement of welding and working environment
