One of the key issues in the transmission of crude oil and its products is to ensure safety and protect the environment.
Thanks to the integrated procedures and the dedicated LDS (Leak Detection System) module, PSIcontrol/Oil significantly increases pipeline operation safety.
PSI has developed a wide range of leak detection methods. These work independently and may be used individually or in combination. The choice of method depends on the specific nature of a pipeline, measuring accuracy, pipe foundation, pumping regimes and other factors. The leak detection and location system may be integrated with the PSIcontrol/Oil module or linked with other SCADA systems via interfaces.
In its usual mode of operation, the PSIcontrol system simultaneously relies on two complementary leak detection methods. The primary leak detection and location approach is by the mass balance method (MCMB) which ensures reliability and excellent sensitivity and, first and foremost, allows leak detection in unspecified conditions. The system additionally relies on the pressure drop method (PS) for highly accurate (±100 m) and rapid location of leaks.
The two complimentary methods enable PSIcontrol/Oil to effectively monitor pipeline tightness and alert operators every time border values have been exceeded.
The requirement in Germany is to employ at least two independent leak detection and location methods. This regulation will soon become law at European Union level. All pipelines in Germany fitted with the PSI leak detection module have been certified for operation by the TÜV certification body and comply with the TRbF 301 (TRFL) standard.
