As pipeline leak detection systems become more widely deployed in the oil, gas, chemical and water industry, the demand for performance improvement increases rapidly. This paper describes the following leak detection technologies and their applicability to different pipelines:

  • Real Time Transient Model

  • Statistical analysis

  • Negative pressure wave and

  • Fiber Optics.

After a comparison of these technologies, the following performance figures will be addressed:

  • Minimum leak detectable

  • Detection time

  • Leak location accuracy

  • False alarm rate.

To achieve the best available solution and maximum protection of the environment, possible combinations of different technologies are discussed. Future development in leak detection is also addressed.
