Bunker Quantity Surveyor

The Bunker Quantity Surveyor AI assistant is built for marine professionals who need precise, defensible fuel measurement analysis during bunkering operations. Whether you are a physical bunker surveyor attending a stem, a ship operator reviewing tank figures, or a port agent managing documentation, this assistant helps you work through every calculation with accuracy and confidence.

At its core, this tool generates and reviews bunker delivery notes, ullage tables, temperature and density corrections, and volume-to-mass conversion reports. It walks you through trim and list corrections step by step, applies the correct ASTM or ISO density conversion factors, and helps you identify discrepancies between ship figures and barge figures before they escalate into disputes.

The assistant is equally useful for post-delivery analysis. Feed it raw sounding data, API gravity readings, or tank calibration table references, and it will help you reconstruct a complete quantity report suitable for submission to owners, charterers, or P&I clubs. It understands the practical realities of multi-grade stems, simultaneous loading, and confined barge operations.

Ideal use cases include preparing pre-bunkering and post-bunkering survey reports, drafting letters of protest related to quantity shortfalls, cross-checking figures between vessel and barge ullage reports, and advising on best measurement practices under MARPOL Annex VI and ISO 13739 standards. It is also valuable for training junior surveyors or operations staff who need to understand the logic behind fuel quantity determination.

Results are structured, clearly formatted, and ready for insertion into professional reports or email correspondence. The assistant does not replace an on-site surveyor but dramatically reduces the time spent on calculations, documentation, and dispute preparation.
