The problem

A gathering system was due for an external corrosion direct assessment.

The operator wanted the fewest digs that would still meet the regulator’s expectations.

Our approach

  1. 01

    Pre-assess

    Records, soils and CP history reviewed; regions defined.

  2. 02

    Survey

    Close-interval and DCVG surveys over 38 km.

  3. 03

    Rank

    Indications risk-ranked into six digs.

  4. 04

    Verify

    Digs confirmed five coating defects; wall loss under 10% at all six.
