Abstract
The aim of the proposed project is to investigate the effect of viscoelastic coating applied on sections of the subsea pipelines such as field joint coating (FJC) (up to 4 mm thick for non-insulated, non-concrete weight coated pipes) on the coverage and accuracy of long-range ultrasonic inspection techniques. The research will explore the coverage of guided waves technique on pipes coated with a viscoelastic coating. The coverage range is currently set at a maximum of 100 m for uncoated pipes ( (P. Fromme, 2006)) and up to 20 m for non-viscoelastic coated pipes (A. Ghavamian, 2018)).The intrinsic reliability of the non-destructive testing technique will be critically analyzed to detect internal corrosion (minimum of 1.25 mm depth ( (Zahari, 2014))) experimentally. The probability of defect detection as a function of the defect size will be charted to determine the 90% likelihood of detection with 95% confidence. Moreover, the research aims to investigate the effects of having a viscoelastic coating on the resolution and accuracy of the technique.
