Are you addressing the right risk?
Operations in the oil and gas, petrochemical, fertilizer, and chemical industries are high risk, with potential hazard to personnel, property, and environment. A structured approach is required to ensure piping systems, pressure vessels, and storage tanks are safe for operation when exposed to a corrosive environment. The ability to prioritize and address high-risk items can prevent risks of fire, explosions, and shutdowns all whilst saving the asset owners time and cost.
Piping systems, tanks, pressure vessels, and associated equipment are exposed to a corrosive environment that can activate degradation such as corrosion, fatigue, and mechanical damage, leading to corresponding threats of fire, explosions, and shutdowns. These associated threats need to be identified and managed systematically to safeguard life, environment and property.
Traditional inspection methodologies work on a fixed-period basis without considering the risk, while in contrast RBI, the risk is viewed as the product of the consequence and probability of a failure event. This ensures the equipment with high risks are prioritized and focused for inspection activities to reduce the risk level.
Asset owners who have sought DNV’s support in RBI implementation have successfully shown reduced downtime of plants and maintenance cost with improved process availability.
