SOW Attachment 1 - API 653 Appendix C Checklist.pdf

This document appears to be a comprehensive tank inspection checklist, providing detailed guidelines for conducting thorough inspections of various tank components and systems. The checklist covers multiple aspects of tank maintenance and assessment, including foundation, concrete ring, shells, roofs, access structures, and various appurtenances. Key inspection areas include examining foundations for levelness, checking concrete rings for cracks and settlements, inspecting shell surfaces for corrosion and leaks, evaluating roof conditions, assessing manways, nozzles, piping manifolds, and conducting detailed examinations of floating roof seal systems, swing lines, and other critical tank infrastructure components.

The inspection protocol is extensively structured, with each section (1.0-2.0) breaking down into specific sub-sections and individual inspection points (C.X.X.X), providing granular guidance for inspectors. Inspections focus on detecting potential issues such as corrosion, structural weaknesses, seal integrity, drainage problems, and mechanical damage. The checklist emphasizes visual inspections, measurements, testing of various components, and checking for signs of wear, leakage, and structural compromise across different tank types and configurations. The comprehensive nature of the document suggests it is likely a standardized procedure for ensuring the safety, reliability, and operational integrity of industrial storage tanks.
