221B or bunker detective surveys are carried out by our surveyors on behalf of the charters to find concealed (hidden) bunker fuel onboard.
In order to prevent the loss of bunker fuel, our qualified bunker surveyor’s will offer impartial, independent quantity measurement inspection services for marine fuel, providing a detailed bunker survey report highlighting and assuring the not declared fuel on board.
How Bunker Fuel is Concealed?
There are many ways to conceal fuel on a vessel – some of the examples are:
•Use of ‘magic pipes’
•Altered sounding pipe lengths
•Non-class approved and / or altered sounding tables
•Sounding tapes not properly calibrated
After completion of the survey we provide the client with a detailed report, signed and stamped by our surveyor, the captain and chief engineer of the vessel.
