Gas oil inspection
Gas oil inspection ensures quality control at every stage of the logistics chain, minimizing trade risks associated with non-compliance with agreed specifications, incorrect quantities, or incomplete documentation in gas oil export and import operations.
CISS GROUP provides professional gas oil inspection services for leading oil corporations and international trading companies. Inspections take place at intermediate storage facilities, manufacturing plants, and ports worldwide, ensuring compliance with contractual obligations and international standards.
Gas oil inspection varies based on its type:
- Light Gas Oil – A liquid, low-viscosity fuel that flows easily.
- Heavy Gas Oil – A more viscous substance that thickens under low temperatures, complicating measurement and sampling.
Gas oil consists of paraffinic hydrocarbons (alkanes), naphthenic hydrocarbons (cycloalkanes), aromatic hydrocarbons (anthracene, indole, other arenes), and trace impurities containing heteroatoms. It is unsuitable for standard automobile engines and is primarily used as an additive. Storage and transportation tanks must be safeguarded against static electricity. As a hazardous material, gas oil requires stringent safety measures during transport and storage. It must be kept in hermetically sealed containers within ventilated, covered warehouses, away from moisture, direct sunlight, and heating devices.
Accredited CISS GROUP inspectors and laboratory technicians conduct gas oil inspections at all points along the supply chain.
The main stages of gas oil inspection:
Incoming & outgoing gas oil inspection
Inspections occur during the transfer of gas oil to storage tanks, ship/barge tanks, road tankers, railcars, elevators, or port facilities. Inspectors assess storage suitability, verify cargo purity and homogeneity, and ensure the absence of foreign odors and contaminants.
Pre-loading container & vessel hold cleanliness inspection
Inspectors conduct visual examinations of empty containers and vessel holds to confirm their cleanliness and suitability for gas oil transport. This includes checking internal surfaces, lock integrity, hinges, fasteners, and rubber seals.
Loading process monitoring & sampling
During loading, inspectors oversee cargo transfer, verify gross and net weights through re-weighing, and perform weight checks using the draft survey method. They control fumigation processes, visually assess cargo quality, and collect samples per international sampling standards. Once loading is complete, inspectors seal containers and holds and record all data in comprehensive reports accessible to clients. CISS GROUP offers 24/7 loading inspection and sampling services.
Laboratory analysis of gas oil quality
Gas oil quality is tested exclusively in accredited laboratories, following international contract specifications. Key parameters analyzed include:
- Density
- Total sulfur content
- Mercaptan sulfur content
- Flash point
- Mechanical impurities
- Color
- Fractional composition
- Water content
- Pour point
- Viscosity
- Ash content
- Coking capacity
- Water-soluble acids and alkalis content
Photo & video documentation
Inspectors document each stage of the inspection process through detailed photographs and video recordings, timestamped for verification. Upon completion, CISS GROUP provides clients with a comprehensive visual report covering all inspection phases.
Certification & digital security
A final certificate or inspection report is issued upon completion. Each document features a unique QR code linking to the CISS GROUP website, where PDF versions are securely stored. Certificates are digitally signed with cryptographic security, ensuring authenticity and integrity.
Digitally signed certificates play a critical role in trade financing, as banks often require them to validate the integrity of transactions when processing letters of credit.
CISS GROUP ensures compliance with global quality standards, mitigates trade risks, and provides 24/7 inspection availability worldwide. With accredited laboratories, experienced inspectors, and digital security measures, gas oil inspection services offer complete reliability and transparency in every transaction.
