The title of the paper denotes two attributes:
“Inspection” reveals “past” events, i.e., inspection technologies determine the corrosion rate “after” corrosion had caused loss of material
“Monitoring” reveals “Present” situation, i.e., monitoring techniques determine the corrosion rate at the time of monitoring
“Model” predicts the “future” situation, i.e., modeling predicts the “futuristic” corrosion rate based on system operating conditions.
The paper discusses “past” developments, “present” status, and “future” advancements of inspection, monitoring, and modelling technologies.
The main objective of the paper is on Attribute #2.
In the past, the number of internal corrosion related incidences was more than 3 per 1,000 kilometers (km) of pipelines per year
In the present, the number of internal corrosion related incidences hovers around 0.5 per 1,000 km of pipelines per year
In the future, the industry’s goal is to bring the number of incidences to “ZERO”.
This paper explains “effective” and “economical” actions that are required to achieve the “ZERO” incidence goal and the roles of inspection, monitoring, and modeling activities in achieving the goal.
