1.0 Why is Bunker Survey important?

Bunkers are most a times a key financial drainer of a ship’s operations costs, with a risk of diminishing any reasonable profits to the ship owners/ charterers. The risk is even higher or even becomes a painful reality where accountability in the use of bunkers onboard, and/or bunkers supplied is not followed/ is of poor standard.

Determining the accurate quantity of bunkers remaining onboard at the time of ship delivery, redelivery or any time is crucial in avoiding disputes and disappointments. This can also assure you that your ship is safe whilst, on the high seas, cases have occurred where ships have been lost at sea due to poor accountability with bunkers.

Proper determination of bunkers onboard, by a team that values integrity is needed to help you know the exact situation onboard the ship.
