A fuel inspection survey is a technical assessment carried out to verify the quality, quantity and compliance of fuel delivered to a vessel. Since fuel represents one of the highest operational costs in maritime transportation, ensuring that the product is delivered correctly and meets international standards is vital. Issues such as low-quality fuel, excess water content, incorrect density values, stability problems or bunker discrepancies may cause severe engine damage, performance loss and financial disputes.

With the enforcement of low-sulfur regulations and global compliance requirements under MARPOL Annex VI, independent fuel inspections have become essential. A professional bunker survey provides transparency, protects the interests of all parties and eliminates disputes related to volume shortages, contamination or specification deviations.

Kuzey Marine Survey performs fuel inspections in full compliance with bunker delivery procedures, IMO requirements and international measurement standards. The process begins with pre-delivery tank soundings on board and on the supplier’s barge or terminal tanks. These measurements allow accurate calculation of the actual delivered volume.

Representative samples are then obtained during continuous fuel flow at the manifold. Each sample is properly sealed, labeled and signed by all parties. Laboratory analysis includes testing viscosity, density, sulfur content, water content, flash point, sediment levels and stability characteristics—especially important for VLSFO and blended fuels.

Operational monitoring continues throughout the bunker transfer. Fuel temperature, pressure, pumping rate, line integrity and potential contamination risks are documented thoroughly. After the operation, all measurement data are compared and verified, ensuring full transparency for cargo owners, operators and P&I clubs.

Fuel inspection requires advanced engineering knowledge, bunker experience and regulatory awareness. Kuzey Marine Survey’s dedicated team conducts every survey with precision, ensuring accurate reporting supported by photographic evidence, sampling logs and measurement tables.

Our reports provide a clear assessment of fuel condition, delivery accuracy and potential operational risks. We also highlight any deviations from industry standards and offer recommendations to reduce future risks. By identifying issues early, operators can prevent costly mechanical failures and ensure smooth vessel performance throughout the voyage.
