Corrosion Control Knowledge and Technology Integration for Safer California Natural Gas Pipeline System
UCLA is preparing a corrosion detection technologies assessment to identify methods and instruments best suited to collecting the data needed to perform corrosion risk assessments. The project is also developing an integrated corrosion model optimized for use by gas system operators to manage corrosion risks and prioritize the use of mitigative and preventative measures.
Risk management approaches used by gas system operators have been qualitative and insufficiently predictive. The understanding of many pipeline threat mechanisms, especially interaction between various corrosion mechanisms, is not fully matured. Either current models are too simplistic or the phenomena are too complex to mathematically reproduce. This project is integrating detection technologies, corrosion risk assessment methodologies, and risk management optimization approaches to create a new quantitative corrosion risk management approach.
The project will improve safety by enabling the gas pipelines with the highest corrosion growth rates to be prioritized for mitigation measures.
Providing an improved understanding of corrosion damage to gas pipelines will lead to fewer accidental methane emissions and service disruptions.
The Association for Materials Protection and Performance estimates that corrosion damage in U.S. transmission pipelines costs $7 billion annually. Savings up to $250 million per year can be achieved in California's gas system by identifying the most cost-efficient technologies and analytical capabilities to better manage corrosion risk for the gas pipeline system.
