A bunker quantity survey verifies fuel quantities at a defined time using tank soundings or ullages, temperatures, density information, vessel calibration tables and agreed correction factors.
Typical process
The surveyor confirms relevant tanks, reviews records, witnesses measurements where practicable, performs calculations and records any access or measurement limitations. The final statement should identify the basis of calculation and agreed or disputed figures.
Prepare before attendance
Provide tank tables, recent sounding records, fuel receipts, density data, vessel trim and list information, and safe access to the measurement points.
