Description

Technical Field

[0001] The utility model relates to the technical field of pipeline supports, in particular to a pipeline fixing support of an offshore platform. Background Art

[0002] The pipelines of offshore platforms are an important part of the offshore oil and gas extraction and transportation system. They are responsible for safely and efficiently transporting the oil and gas resources on the seabed to onshore or other processing facilities. The installation and laying of pipelines on offshore platforms is a complex engineering task. During the installation process, it is necessary to consider the support and fixing methods of the pipelines to ensure their stability and safety in the marine environment.

[0003] The utility model patent with the authorization announcement number CN211779401U discloses a pipeline support and an offshore operating platform, which includes a pipe clamp, which is used to be sleeved on the pipeline; a support assembly, one end of which is connected to the pipe clamp and is used to support the pipe clamp, wherein the height of the support assembly is adjustable; and a base plate, on which the other end of the support assembly is installed. The height of the support assembly is adjustable, which can adapt to the expansion and contraction changes of the pipeline, provides good support for the pipeline, and the installation and adjustment are simple and fast. In addition, it can compensate for manufacturing and installation errors, and is easy to install and maintain.

[0004] Although the pipe bracket and the offshore work platform are convenient for adjusting the installation height through the support components, the device still has shortcomings when in use. Specifically, when installing the pipeline, the pipe bracket can only install and support the pipeline horizontally. However, due to the complex structure of the offshore platform, the pipeline needs to be installed and laid in an inclined state when passing through some structures. It is difficult to adjust the installation angle of the bracket and cannot meet the installation requirements in different scenarios. In view of this, we propose a pipe fixing bracket for an offshore platform. Utility Model Content
