| Objectives | To investigate sensitivity, reliability and repeatability of data generated through the SCT technology particularly in relation to conventional inline inspection data. Publication of a technical paper / thesis on the work with discussions on the findings, recommendations and suggestions for further work. | |
| Abstract | The key problem relates to pipelines which cannot be internally inspected and the secondary problem is the risk of corrosion, caused by disbondment of coating systems, primarily coal-tar enamel, on buried pipelines. There are a number of limitations associated with current methodologies and the SCT inspection system has the potential to identify defects and features which are currently not detectable using existing techniques thereby reducing the risk of failure on such pipeline systems. This project is an industry sponsored CASE studentship. The key deliverables are as follows: Review existing pipeline routes scanned through pre-existing surveys. Together with additional satellite positioning data, carry out a detailed review and comparison of known locations ( 2m) of In-Line-Inspection (ILI) with SCT. The emphasis of the analysis will be on defect characterisation/categorisation. Laboratory based study of defects manufactured in pipes. This study will aim to re-create features discovered in objective 1 with the aim to explore reliability and repeatability of measurements. Investigate conditions for SCT performance. a. Perform repeat hydrostatic testing on defects created in 2 to determine the relationship between pressure cycling and magnetic features. b. Investigate the effect of ILI runs on the base characteristics of the pipeline. Initially laboratory based experiments will be conducted simulating the effect of ILI runs in lab-based pipes. Hydrostatic testing will be performed to re-create operational conditions for the build-up of stress. In collaboration with NG the project will seek to collect field data with measurements, before, during, and periodically after ILI.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
