Fitness-For-Purpose (FFP) analysis is an engineering study by which the capacity of a pipeline is determined under current and future operating conditions. FFP is one of the fundamental tools of an Integrity Management Program (IMP).
The main objective of FFP analysis is the assessment of the integrity of pipelines that contain anomalies which may have originated during manufacturing, construction, or service. The most common anomalies which affect the current and future capacity of pipelines include metal loss, geometric anomalies or deformations, laminations, cracks and crack-like anomalies, all of which are detectable with ultrasonic inline inspection (ILI) robots. Anomalies are assessed according to accepted codes, standards, or recommended practices. Combining the most advanced assessment methods (e.g. Finite Element Analysis) with precise high-resolution ILI data enables precise anomaly assessment, reduces conservatism, and, therefore, helps to avoid unnecessary repairs or pressure restrictions. Once anomalies are detected and sized, their mechanical effect must be determined by calculating the remaining resistance of the pipeline. This is completed using analytical methods that determine whether the affected pipeline can acceptably remain in service.
Results are expressed in terms of failure pressure, safe pressure, or stress level. The different evaluation methods are described in industry standards. The assessment results are documented in a technical report that describes the evaluation parameters, the type and dimensions of the analyzed anomalies, methodologies used, results, conclusions, and recommendations.
We use the most accurate and innovative ultrasonic technology on the market to inspect your pipelines to provide value that you can put back into your Integrity Management Program, all while keeping in mind our common goals: pipeline integrity, cost reduction and protecting the environment.
