The two fundamental types of leak detection, internal and external are discussed along with sensitivity, accuracy, reliability, and robustness – the four key criteria.  Key challenges of oil leaks and leak detection versus gas are covered during this module which makes extensive use of hydraulic gradients.  This module simplifies and explains what to many is the “black art” of leak detection

Learning Objectives

  • Name and explain each of the four leak detection criteria.

  • Explain what is meant by internal and external leak detection.

  • Explain what is meant by instrument error.

  • Explain how instrument error affects sensitivity.

  • Explain what the acronym CPM stands for.

  • Explain the term parameter deviation.

  • List events that cause transient conditions.

  • Explain how transients make leak detection more challenging.

  • Explain the principles of signature recognition CPM.

  • Explain why API 1130 says CPM systems are not good at detecting small leaks.

  • Explain what happens to the centrifugal pump curve when a rupture occurs.

  • Explain what happens at the next downstream station when a rupture occurs.
