Future possibilities in NDT for feature identification and sizing, material identification and stress measurement
Prof. Gerd Dobmann
(Formerly at IZFP-Institure for NDT, Fraunhofer Gesellschaft Saarbruecken)
This presentation will relate to the future possibilities and foreseeable trends up to 2030 in the field of non-destructive testing and examination. It will address the issues of detection, sizing, identification and localization of features and provide the basis for discussing future capabilities of in-line inspection tools. in pipe wall or coating.
Added value of knowing actual material properties of pipe inspected for integrity assessment (especially fracture toughness)
Dr. Brian Leis
(Principal of his consultancy, B N Leis Inc., focusing on integrity and risk management issues in the oil and gas industry)
For full integrity assessment it is not only necessary to have precise data on defect size and location, but it is also essential to have access to reliable data regarding material specifications of the actual linepipe being investigated. In other words identification of the actual material resistance of the pipe being inspected, i.e. Yield, UTS, fracture toughness etc. The presentation will address inspection/diagnostic technologies and/or processes that will be available and feasible in order to collect this data.
Added value of knowing actual true loading of pipeline or structure inspected for integrity assessment purposes
Dr. Roger King
(Independent consultant and expert in corrosion in the oil, gas, civil and nuclear industries)
Integrity assessment and fitness-for-purpose investigations require good knowledge of the internal and external loads acting on the pipeline being investigated. This presentation will address whether or not it is also essential to have precise knowledge of local loading conditions within the vicinity of features in order to assess fitness-for-purpose, including inhomogeneous stress distributions at notches, cracks or due to residual stresses present.
