Finite Element Assessment

Use accurate 3D modelling and assessments for maximum safe working pressure

NDT Global uses state-of-the-art computational Level 3 assessment methods, including finite element analysis (FEA). Such assessments provide precise and accurate predictions of the failure pressure of anomalies.

Conventional assessment methods are widely used and accepted, despite their well-known conservative results leading to decreased throughput and unnecessary pipeline repairs. Although these methods have been refined over the years, they continue to yield too-conservative predictions for maximum allowable safe working pressure.

FEA is based on the actual 3D geometry of the damaged pipe (anomaly + pipe joint) and can even account for specific material properties. This reduces the degree of conservatism and helps avoid costly excavations and repairs in difficult-to-access locations. FEA also allows the assessment of combined anomalies (e.g., dents with cracks or dents with metal loss), which is not possible with standard methods.

NDT Global’s high-resolution inline inspection robots accurately and reliably detect and size metal loss anomalies and crack-like flaws, and our ultrasonic geometry technology provides detailed geometry and deformations of pipe joints. Combining such detailed information yields accurate 3D modelling and FEA assessment to provide the most accurate estimation of your pipeline’s failure pressure.
