Completed. |
| Description |
The objective is to
evaluate current and candidate methods for detecting and monitoring
corrosion damage in risers and develop ranking criteria for riser
inspection. Offshore pipeline failure statistics have been collected for
more than 30 years now. Pipelines predominantly fail as a result of
corrosion. Pipeline Risers are the part of the pipeline system that fails
most often. Risers are either visually or internally inspected. Due to
outside coatings visual inspection can be inefficient and inaccurate.
Current internal inspections, create more false positives and sometimes miss
significant defects. In order to reduce the amount of hydrocarbons released
into the environment, MMS needs research on the evaluation of methods of
detecting and monitoring of corrosion damage in risers. This will aid
Regional MMS offices in detecting damage from corrosion in risers before a
failure can occur. |
