A Submarine Pipeline Leakage Monitoring System

Abstract

The invention relates to a submarine pipeline leakage monitoring system, comprising a controller, a flow sensor, a pressure sensor, a temperature sensor and a central main computer; the inlet end and the outlet end of the pipeline to be monitored are provided with a flow sensor, a pressure sensor and a The temperature sensor, inlet flow sensor, pressure sensor and temperature sensor collect the flow, pressure and temperature signals at the inlet in real time, and send them to the first controller; the flow sensor, pressure sensor and temperature sensor at the outlet collect the flow, pressure and temperature at the outlet in real time. The temperature signal is sent to the second controller; each controller sends the signal to the central host computer through the Ethernet switch, and the leakage monitoring system in it displays the information in real time and judges whether the pipeline to be monitored leaks. Then the leakage alarm will be carried out, and the leakage amount and leakage position will be calculated and displayed; the central host computer will send the received signal and judgment result to each remote monitoring equipment.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a submarine pipeline leakage monitoring system. Background technique [0002] With the continuous increase of submarine pipelines, submarine pipelines have gradually become the lifeline of offshore oil and gas. Due to the complex submarine environment, submarine pipelines are prone to aging and corrosion, resulting in leakage of submarine pipelines. On the one hand, leakage of submarine pipelines will pollute the environment, on the other hand, it will cause economic losses, and more seriously, it will cause casualties. Therefore, the monitoring of submarine pipeline leakage has become an increasingly urgent technical problem to be solved. [0003] There are many researches on land pipeline leakage monitoring technology in China, the main methods are negative pressure wave method and acoustic wave method, because negative pressure wave method and acoustic wave method are highly sensitive t...

Problems solved by technology

Existing foreign submarine pipeline leakage monitoring methods mainly include pressure point analysis method, optical fiber method and real-time model. Among them, the monitoring results of pressure point analysis method are greatly affected by the instrument, and the optical fiber method requires the transformation of the submarine pipeline, and the transformation is difficult. Large, easily damaged subsea pipelines, real-time model monitoring is expensive and expensive
