Seafloor petroleum pipeline plugging and rush-repair equipment

Abstract

The invention belongs to the field of seafloor petroleum pipeline plugging and rush-repair equipment, and particularly relates to seafloor petroleum pipeline plugging and rush-repair equipment which comprises a plugging box body, a pollution source positioning part is arranged at the top of the plugging box body, and a plugging box support is fixedly arranged in the direction, close to the plugging box body, of the pollution source positioning part. The plugging box body is connected with the plugging box support through a separating part, a pipeline cleaning part is arranged in the plugging box body, pipeline positioning parts are arranged on the two sides in the plugging box body respectively, and pipeline plugging parts are arranged on the two side walls of the plugging box body respectively. And the damaged and polluted part of the pipeline can be automatically positioned, and the damaged part of the pipeline is blocked.

Description

technical field [0001] The invention belongs to the field of plugging and emergency repair equipment for submarine oil pipelines, in particular to a plugging and emergency repair equipment for submarine oil pipelines. Background technique [0002] People have been developing and researching the ocean for a long time, and the exploitation of seabed crude oil and natural gas is the top priority in ocean development projects. However, due to the complex environment and high pressure conditions of the seabed, as well as the influence of the characteristics of crude oil and natural gas, the submarine oil and gas transportation pipelines have been corroded and damaged to a certain extent. [0003] Especially in deep sea operations, with the complexity of the marine environment and the increase in the use time of pipelines, damage to submarine oil pipelines and even oil and gas leakage often occur. Or self-fatigue damage, will lead to significant economic losses and pollution dama...

AI Technical Summary

Problems solved by technology

However, due to the complex environment and high-pressure conditions of the seabed, as well as the influence of the characteristics of crude oil and natural gas, a certain degree of corrosion and damage has been brought to the submarine oil and gas transportation pipeline.

[0003] Especially in deep sea operations, with the complexity of the marine environment and the increase in the use time of pipelines, damage to submarine oil pipelines and even oil and gas leakage often occur. Or self-fatigue damage, will lead to major economic losses and environmental pollution damage

At present, there is no reliable plugging device for deep-sea pipeline damage. Therefore, there is an urgent need for a submarine oil pipeline plugging and repairing equipment that can automatically locate and locate the damaged part of the pipeline and block the damaged part of the pipeline.
