Why You Need Independent Bunker Surveyors in Tanzania
Bunker fuel is the single largest expense for any vessel operator. Inaccurate measurements and short deliveries can lead to substantial financial losses. An independent bunker survey is your best defense.
The Risk of Short Delivery
Disputes over the quantity of fuel delivered are common. Without an impartial surveyor, you risk paying for fuel you never received.
Charter Party Disputes
Disagreements over the quantity of fuel remaining on board (ROB) at the start or end of a charter can lead to costly delays and legal conflicts.
Uncovering Hidden Losses
Undeclared bunkers and inaccurate tank calibrations can hide significant fuel losses. Only an expert surveyor can uncover these issues.

The Reality of Bunkering in Tanzania
Without an independent expert on your side, you are exposed. Relying solely on the figures provided by the supplier or the vessel’s crew creates a significant financial risk. Short deliveries are a constant threat. Disputes over On-Hire and Off-Hire quantities can sour relationships and lead to costly arbitration. You are left questioning every delivery, eroding trust and impacting your bottom line.
