Pipe systems, tanks, pressure vessels and associated equipment are exposed to degradation such as corrosion, fatigue and mechanical damage which lead to corresponding threats of fire, explosions and shut-downs. These threats need to be managed in a systematic approach to safeguard life, environment and property. To do so, the associated risks need to be identified and managed in a recognized and trustworthy manner.
Traditional inspection methodologies can work on a fixed period basis whereas in the context of Risk Based Inspection, risk is considered as the product of the consequence and the probability of a failure event. This ensures that the objects with high risk are prioritized and items with insignificant risk can be given less attention. Successful implementation of Risk Based Inspection by DNV GL’s customers has been shown to both reduce maintenance costs and improve process availability.
