- Additional information
- The proposed methodology considers, for the first time, the 3D nature of defects in the use of ultrasonic data from in-line-inspection of offshore pipelines, avoiding the usual crack-like recharacterisation. The procedure allows the severity of defects to be screened based on geometry-based analysis and generates a defect severity ranking using image-based FEA stress analysis, reducing the dataset for analysis to significant proportion, depending on the level of conservatism wanted. The work has been funded by BP and the Spanish Government and triggered new projects funded by YPF (Argentina) and the Carbon Trust for analysing corrosion defects in offshore structures.
