C-FER has developed a simplified reliability-based approach that eliminates the computational effort required for of the traditional reliability-based approach. This approach, called the Limit State Design (LSD) approach, uses a set of deterministic safety factors that have been calibrated to produce a similar risk level to the reliability-based approach. Since the safety factors are deterministic, their application does not require probabilistic calculations.
A comparison of the number of repairs required by the LSD approach, an operator full reliability-based approach, and the CSA Z662 (Clause 10.10.2) deterministic approach on real pipeline cases to determine corrosion repairs has been published in the paper, Implementation of Reliability-Based Criteria for Corrosion Assessment, covering almost 1200 km of pipeline and over half of millions of corrosion features.
The results are shown in the figures below:
