Atteris and Saltel compiled current industry knowledge and published information on the internal patch repair method and its compatibility with pipeline design codes, then defined Woodside’s pipeline design data ranges and other key data (e.g. mechanical connectors, defect properties, etc.) that will affect the repair method. A detailed Failure Mode Effects and Criticality (FMECA) workshop was conducted to identify key risks to the design and then all issues were either designed-out or addressed in the qualification programme scope. The repair method design ultimately received a “Statement of Endorsement” from DNVGL and is (as at Q2 2018) now ready for the next phase of technology qualification – full scale qualification testing.
