Maintaining subsea pipelines is a crucial process to keep operations flowing. It is paramount for both the safety of offshore operations and the upkeep of legal regulations. It’s important therefore for the equipment used in the flow assurance process to be accurate and reliable. Not only does it need to find any integrity issues, but ideally, it must do so without disrupting operational pipelines.
The use of hotspot inspections
In-line inspections aren’t always feasible. In this instance, operators may fall back on ‘hotspot’ inspections in localised areas. From this, more inspections can be carried out — but it isn’t efficient or cost-effective to do this. With a field-proven subsea CT scanner, operators do not have to waste time on these hotspot inspections. Instead, the software can find defects and inform the operator whether or not these issues are impacting the pipeline enough to push it out of its specified tolerance. With these issues accounted for, operators can then undertake a more detailed scan of that area, rather than extending the...
