In times of global warming, former pipeline leakages or rig disasters, the HSE (Health Safety Environment) pressure on the Oil/Gas industry increased more and more. 

An ILI (In Line Inspection) run is extremely important to verify the pipelines’ condition and therefore prevent any harm to people or nature. 

The most common procedure to inspect a pipeline is with the help of a MFL (Magnetic Flux Leakage) pig or with an UT (Ultrasonic Tool) run. 

As these pigs are sensible in terms of mountings, sensors, measurement, etc., it is recommended to inspect a pipeline after the cleaning campaign. 

Quite simply, the most important advantage of cleaning a pipeline prior inspection is the combined effect of getting good results (full pipeline coverage and high quality data) after just one ILI run. 

This is cost effective as well. 

Based on the ILI run result, specific maintenance work on the pipeline can be executed. 

On a regular basis, the pipeline should now be cleaned and re-inspected to keep the cleanliness and verify the pipelines’ condition.
