... predictions shall be employed for design scenarios, and API 579 ( Ref 16 ) directs users to use the −2σ design curve for fitness-for-service (FFS) applications. API 579 removes some conservatism associated with the −3σ design curve by permitting the use of the −2σ curve for FFS assessments. The logic behind...
