Integrity and Inspection of Unpiggable Coated Subsea Pipelines

Download the Case Study
on Concrete Coated Pipelines

Discovery™ non-intrusively scans through both coated and uncoated subsea pipelines to build up a full tomographic image of pipe wall thickness. This allows operators to inspect unpiggable or difficult to inspect pipelines (including pipe-in-pipe, pipe bundles, risers and jumpers) without stopping/deferring production, saving up to 35% on the cost of inspection campaigns, compared with conventional scanning techniques.

Image highlighting benefits of using Discovery in unpiggable subsea pipelines Accurate sizing of wall thickness can be made in minutes with a high resolution image of the pipe wall(s) being provided from an external scan of the pipeline. The tomographic image shows flaws within the pipe walls and allows operators to plan for the future life of the pipeline. Deployment of Discovery™ brings several benefits to integrity specialists:

  • Measurements can be taken online with no interruption to production
  • Eliminate the vast cost and risk of removing coatings subsea
  • Eliminate interruption to production and normal pipeline operations
  • Allows unpiggable pipelines that were previously considered impossible to inspect to be assessed
  • Reduce operational intervention time so critical decisions can be made immediately by obtaining data online
  • For the first time, get a complete picture of the integrity of your complex pipeline systems:
  • pipe bundles, pipe-in-pipe, flexibles, CRA lined, plastic lined
  • Removes the concern and risk of internal inspection tools getting stuck and interrupting production
  • It can be deployed quickly by ROV and no modification to the pipeline is required
