The internal vessel and tank lining program for a state-owned Middle East Oil Company was reviewed. A revision in the strategy for selection, application, and maintenance of applied internal linings was suggested. Several major changes to current practices were recommended. First, qualification testing for specific products should replace the generic chemistry recommendations for vessel and tank linings. Second, a qualified coating inspector should be present for all phases of an internal coating job rather than relying on strict adherence to written standards. Third, more thorough record keeping for all tank and vessel coatings would enable better tracking of field performance of specific coating products.
