Acoustic signatures of leaking pipelines

使用计算机管道监测系统对输送液态碳氢化合物的管道进行持续监测，以检测流体流动和体积中的水力异常，这可能表明发生了泄漏事件(即泄漏)。这些系统提供了一种实时检测大型释放的有效手段；然而，它们在检测较小的释放率方面只取得了有限的成功。不幸的是，长期未被注意到的小型释放事件可能会对环境造成重大影响。

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.
