For practical implementation, start with a baseline condition assessment to document coating condition and CP performance. Establish a routine schedule for coating repairs and CP testing—many operators find semiannual to annual CP checks effective, with more frequent checks where interference or aggressive environments exist. Pay special attention to areas prone to moisture accumulation, HVAC condensate, gutter run-off, and mechanical damage.

Common challenges include poorly documented past repairs, CP interference from nearby structures or DC-powered equipment, and inconsistent inspection records. Integrating RP 586 recommendations into an asset integrity management program, and keeping thorough records, reduces these gaps and aids regulatory compliance. api rp 586 pdf

Corrosion of aboveground petroleum storage tanks and associated piping is a persistent threat to safety, environmental protection, and operational uptime. API RP 586 provides recommended practices designed to help operators prevent and mitigate external corrosion using a combination of design, coatings, cathodic protection (CP), inspection, and maintenance. Common challenges include poorly documented past repairs, CP
