Tank Inspection is a comprehensive non-destructive evaluation service used to assess the structural integrity, floor condition, and leak tightness of above-ground storage tanks. Storage tanks are critical assets used for hydrocarbons, chemicals, water, and process fluids, and failures can lead to safety incidents, environmental damage, and regulatory non-compliance.
This service integrates advanced inspection techniques to evaluate tank bottom condition, identify corrosion or metal loss, detect active leaks, and support integrity assessment and maintenance planning. Tank inspection plays a key role in risk reduction, life extension, and compliance with statutory inspection requirements.
Why Tank Inspection Is Required
Tank bottoms are particularly vulnerable to corrosion due to soil-side exposure, moisture ingress, and aggressive service conditions. Tank inspection helps address challenges such as undetected bottom corrosion, floor thinning, leakage risk, and uncertainty in tank fitness for continued operation.
Regular inspection enables early detection of degradation, prevents catastrophic failures, supports informed repair decisions, and ensures compliance with applicable tank inspection standards.
Scope of Inspection
Tank inspection services typically cover:
Tank bottom plates and annular ringsShell-to-bottom weld areasFloor profile and settlement assessmentLeak detection and tightness verificationIn-service and out-of-service tanks
Inspection Methodology
Tank inspection is carried out using a structured integrity-driven approach that begins with review of tank design, construction details, service history, and inspection objectives. Based on tank condition and operational constraints, appropriate inspection techniques such as Magnetic Flux Leakage, Acoustic Emission Testing, or Vacuum Box Testing are selected.
Inspection data is collected using specialized equipment and analysed by experienced inspectors and engineers. The findings are used to assess corrosion severity, identify active leaks or deformation, and develop recommendations for repair, continued operation, or further integrity evaluation.
Key Benefits
Tank inspection improves safety, prevents environmental incidents, supports regulatory compliance, reduces unplanned downtime, and provides reliable data for maintenance and life management decisions.
Industries and Applications
Tank inspection services are widely applied in refineries, oil and gas terminals, petrochemical plants, chemical industries, power plants, water treatment facilities, and bulk storage installations.
Tank Inspection provides a reliable and data-driven assessment of storage tank integrity. By identifying bottom corrosion, deformation, and leakage risks early, this service supports safe operation and long-term asset reliability.
