Underwater pipe clamp mounting method

Abstract

The invention relates to an underwater pipe clamp mounting method, which comprises the following steps: (1) the mounting position of an underwater pipe clamp (1) and the positions of three platform winches are determined; (2) the mounting datum line of a plurality of pipe clamps is determined; (3) the concentricity position of a plurality of pipe clamps is determined; (4) a plurality of pipe clamps are mounted, namely 1) a first steel wire (9), a second steel wire (10) and a third steel wire (11) of the three platform winches are adjusted, so as to form a three-dimensional coordinate system; 2) one pipe clamp (1) is placed to the mounting position, a flange tightener steel wire (12) is taken as the mounting datum line of an outer clamp (6), the mounting position and angle of the pipe clamp (1) are determined, the pipe clamp (1) encircles a pipe frame construction member (2), and the pipe clamp (1) is fixed; and the rest pipe clamps (1) are mounted by repeating the steps 1) and 2). The invention can simultaneously respectively carry out pipe clamp mounting fixing and coaxial adjusting, and underwater pipe clamp mounting efficiency and the coaxial accuracy ratio of pipe clamps are improved.

Description

technical field [0001] The invention relates to a method for installing pipe clips, in particular to a method for installing underwater pipe clips. It belongs to the field of offshore oil engineering. Background technique [0002] In offshore oil development projects, it is necessary to lay submarine oil pipelines and submarine cables on the seabed. The submarine oil pipeline includes: flat pipe, platform riser and expansion elbow. The platform riser is the main component used to connect the flat pipe and lead the end of the pipeline out of the water along the platform. [0003] After the offshore oil field is completed and put into production, due to the further development of the oil field and the establishment of a new platform, it is necessary to establish new submarine pipelines and new cables, which requires the installation of new risers, cable protection pipes and riser clips on the original platform. Or cable protection tube clamps are used to fix the riser or cab...

AI Technical Summary

Problems solved by technology

This method increases the error rate of the concentricity of the pipe clamp 1 and the working time above the water surface 13 and underwater. When the riser is installed in the later stage, it is necessary to adjust the concentricity of the pipe clamp 1 again according to the actual riser. Therefore, The installation steps of the existing underwater pipe clips are relatively cumbersome and cannot be put in place at one time
