Tankers used for transporting hazardous and non‑hazardous liquids – including fuel, chemicals, liquefied gases, and food‑grade products – require regular, thorough inspection to ensure safety, regulatory compliance, and environmental protection. S3iWorld provides independent third‑party inspection services for all types of road and rail tankers, verifying structural integrity, leak tightness, labeling, and emergency systems.
Why Tanker Inspection is Essential
- Prevent spills and leaks – Avoid environmental contamination and product loss during transport.
- Ensure public safety – Reduce risks of fire, explosion, or chemical exposure on roads and rail networks.
- Meet regulatory requirements – Comply with ADR, DOT, PESO, local transport authorities, and HSE regulations.
- Protect cargo integrity – Verify that internal surfaces, gaskets, and valves are clean and functional.
- Facilitate insurance and legal compliance – Satisfy insurer requirements and maintain operating licenses.
Types of Tankers We Inspect
- Fuel and diesel tankers (petrol, diesel, aviation fuel)
- Chemical tankers (acids, solvents, corrosives)
- LPG / LNG tankers (pressurized or cryogenic)
- Food‑grade tankers (milk, edible oils, liquid sugar)
- Vacuum tankers (sewage, sludge, industrial waste)
- Rail tank cars (all commodity types)
Our Tanker Inspection Scope
Each inspection follows a systematic process based on international standards and manufacturer specifications.
Visual & Structural Examination
- External body and chassis for dents, corrosion, or deformation
- Internal tank surface (where accessible) for pitting, cracks, or coating failure
- Hatch covers, manways, and gaskets – seal integrity and ease of operation
- Valves, piping, and flexible hoses – leaks, damage, or wear
- Pressure relief devices and vacuum breakers
Non‑Destructive Testing (NDT)
- Ultrasonic thickness testing (UTT) of tank shell and baffles
- Magnetic particle or dye penetrant testing of critical welds (where required)
Pressure & Leak Testing
- Hydrostatic or pneumatic pressure test (according to design code)
- Leak detection using soap solution or the pressure decay method
Safety & Compliance Checks
- Grounding system continuity and earthing points
- Fire extinguishers (type, location, expiration)
- Emergency shut‑off valves and remote actuation
- Spill containment and drip trays
- Labeling – hazard diamonds, product name, UN number, maximum fill level
- Reflective markings, rear underrun protection, and lighting
Documentation Review
- Previous inspection certificates and repair records
- Manufacturer’s data plate and design code
- Transport permit and insurance documents
Our Inspection Process
- Inquiry & Planning – You provide tanker details (type, capacity, commodity, registration number, location). We schedule a convenient time, often during loading/unloading downtime.
- Pre‑Inspection Preparation – The tanker must be cleaned and gas‑freed if it previously contained hazardous materials. We provide written safety instructions.
- On‑Site Inspection – Our certified inspector performs visual checks, NDT measurements, pressure/leak testing (if required), and safety equipment verification.
- Reporting & Certification – Within 48 hours, you receive a comprehensive report including:
- Tanker identification (registration, chassis number, tank serial number)
- Pass/fail status for each inspected item
- Photographs of any defects or non‑compliant features
- Ultrasonic thickness readings (if performed)
- Leak test results and pressure values
- Recommended corrective actions (repair, replace, re‑test)
- Inspection certificate valid for the period required by local regulations (typically 1 year)
- Follow‑Up & Re‑Inspection – After repairs, we offer a re‑inspection to verify compliance and issue an updated certificate.
Standards & Compliance
Our tanker inspections are conducted in accordance with:
- ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road)
- DOT 49 CFR (US Department of Transportation – Cargo Tank Regulations)
- PESO / CCOE (Petroleum and Explosives Safety Organization) – for many Asian countries
- ASME / API 653 (where applicable)
- Local transport authority and environmental protection agency rules
