Pre-commissioning oil and gas pipelines for field readiness requires a series of tests to validate the system’s structural integrity before introducing the hydrocarbons to be transported. Hydrostatic testing (hydrotesting) for leaks generally involve a flooding and pressurization process— the most important of all pipeline integrity tests. The flooding phase is typically carried out with a diesel-driven water pump, while the pressurization phase requires compressor capacity. Hydrotesting has long been employed to verify pipeline integrity. Several types of information are obtained through this testing process, such as flaws in the pipeline material, stress corrosion cracking and specific mechanical properties of the pipe.
