A pipeline leak monitoring system is a 24/7 monitoring system for crude oil transportation pipelines. It provides immediate alarms and pinpoints the location of leaks in the event of a perforation or leak.
Leak detection methods are mainly divided into two categories: direct and indirect methods. Direct methods utilize pre-installed detection elements (such as leak detection cables or oil-sensitive elements) outside the pipeline to directly detect the leaking medium. This method can detect minute leaks and pinpoint their location, but it requires installation during pipeline construction. Indirect methods infer leaks by detecting changes in pipeline operating parameters, such as pressure and flow rate. This method is less sensitive than direct methods and is suitable for detecting larger leaks (generally around 1%). Its advantage is that it can be installed after pipeline construction without affecting production and can be continuously upgraded.
