Pipelines transporting liquid hydrocarbons are continuously monitored using computational pipeline monitoring systems to detect hydraulic irregularities in fluid flow and volumes, which may be indicative of release events (that is, leaks). These systems provide an effective means of detecting large releases in real time; yet they have shown only limited success in detecting smaller release rates. Unfortunately, small release events that go unnoticed over prolonged periods of time may cause significant environmental impact.

使用计算管道监测系统连续监测输送液态烃的管道，以检测流体流量和体积中的水力不规则性，这可能指示释放事件（即泄漏）。这些系统提供了一种真实的实时检测大量释放的有效手段;然而，它们在检测较小的释放率方面仅显示出有限的成功。不幸的是，长时间不被注意的小排放事件可能会造成重大的环境影响。
