Fitness-for-purpose assessments that provide accurate repair dates for corrosion anomalies
In a Nutshell:
Industry methods provided by ASME for assessing the remaining life of corrosion anomalies can yield results that are over-conservative. Advanced fitness-for-purpose (FFP) methods can be used to gain a better understanding of the actual failure dates of metal loss corrosion anomalies. ROSEN USA has recently used an advanced FFP method called the Plausible Profile Method (P2) to provide increased accuracy in repair dates to a client experiencing complex corrosion in one of their pipelines (in comparison to industry methods such as Detailed RSTRENG, Modified B31 G, Kastner, etc.). This method extended the remaining life of 10+ anomalies by more than three years, potentially saving the client hundreds of thousands of dollars in repairs.
