Oil Storage Tanks & Oil Carrying Tankers Inspection

Oil storage tanks (fixed or mobile) and oil carrying tankers (road or rail‑based) are critical assets in the petroleum, chemical, and logistics sectors. Their inspection is essential to ensure structural integrity, leak prevention, safety of operations, environmental compliance, and regulatory adherence. Regular third‑party inspection of these tanks and tankers helps prevent accidents, contamination, spills, and compliance violations, ensuring safe storage and transport of hazardous liquids like crude oil, diesel, lubricants, and industrial chemicals.

Why This Inspection is Needed

  • Prevent Environmental Hazards – Avoid leaks, spills, and soil/water contamination; maintain safety near populated or ecologically sensitive areas.
  • Ensure Structural Integrity – Detect corrosion, cracks, dents, weld failures, or settlement.
  • Comply with Regulations & Standards – Meet requirements under API 653, API 650, ADR, DOT, PESO, OSHA, ISO 31000, and local HSE authorities.
  • Ensure Safe Transport and Storage – Proper venting, grounding, labeling, and cleaning of tanks/tankers; minimize fire/explosion risks.
  • Facilitate Insurance and Legal Compliance – Required by insurers and legal frameworks for claims, liability, and operational licenses.

Basic Requirements of Oil Tank and Tanker Inspection

Inspection of Fixed Storage Tanks

  • External and internal visual inspection
  • Ultrasonic thickness testing (UTT)
  • Magnetic particle testing (MT)
  • Radiographic testing (RT) of welds
  • Leak testing (e.g., hydrostatic, vacuum box)
  • Corrosion and coating evaluation
  • Tank bottom and shell inspection
  • Ventilation, grounding, fire protection, and manholes
  • Calibration for volumetric accuracy (ISO 7507 / API MPMS)

Inspection of Oil Carrying Tankers (Road / Rail)

  • Body and chassis inspection
  • Tank shell integrity
  • Hatch covers, manways, valves, and drain systems
  • Cleaning and decontamination verification
  • Pressure and leak testing
  • Labeling, grounding system, and fire extinguishers
  • Spill containment and emergency shut‑off devices
  • ADR, DOT, or PESO compliance checks
