Out-of-service (internal) tank inspections involve thorough evaluations of all accessible internal and external tank components by certified inspectors. These inspections, requiring tanks to be taken offline, assess structural integrity, detect leaks, corrosion, and potential environmental hazards. Key areas such as tank shells, roofs, piping, and appurtenances are examined using various NDE techniques.

APEX INTEGRITY INSPECTIONS conducts in-service inspections—also known as external inspections—while tanks remain operational or when internal access is not possible. These inspections involve a detailed visual assessment of the tank’s exterior to identify leaks, shell distortion, settlement, corrosion, and the condition of coatings, insulation, and appurtenances.
