Bunker Survey in Liberia

Independent Bunker Surveyors in Liberia

Liberia’s coastline handles two very different kinds of bunkering trade: general cargo and container calls at the Port of Monrovia, and the bulk carriers loading iron ore at the Port of Buchanan. Observater provides independent bunker survey coverage for both, with surveyors available for rapid deployment to either port or the Monrovia anchorage.

A discrepancy between what was ordered and what was delivered is a cost most vessel operators only discover once the fuel is already burned. An independent surveyor on the manifold during delivery, or sounding the tanks at redelivery, is the only reliable defense against that outcome.

Bunker Quantity Surveys (BQS) in Liberia

Our BQS attendances at Monrovia and Buchanan follow the same internationally recognized method wherever the vessel calls:

• Pre-Delivery Measurement: full tank soundings on both the receiving vessel and the supply barge before bunkering begins.
• Continuous Monitoring: the surveyor remains on-site throughout the transfer, watching flow rate and checking for irregularities.
• Post-Delivery Measurement: tanks re-sounded on completion to determine the final delivered quantity.
• Certified Calculation: quantities calculated to API/ASTM standards and issued in a signed report.

Bunker Surveys at the Port of Buchanan

Buchanan’s traffic is dominated by large bulk carriers loading iron ore for export, vessels that carry substantial bunker stems and where even a small percentage discrepancy represents real money. Our surveyors coordinate with vessel agents to attend alongside loading operations, minimizing disruption to the vessel’s port call while giving owners and charterers an independent figure they can rely on.

Bunker Surveys at the Port of Monrovia and the Offshore Anchorage

Monrovia serves as Liberia’s principal gateway for general cargo and containers, with STS and anchorage bunkering a routine part of operations offshore, as it is throughout much of West Africa. Our surveyors attend by launch when required, taking the same tank soundings, temperature readings, and samples as they would alongside the berth.

On-Hire & Off-Hire Surveys in Liberia

For owners and charterers beginning or ending a charter via a Liberian port, an accurate fuel baseline is essential to a fair settlement. The On-Hire Survey establishes that baseline when the vessel is delivered into service; the Off-Hire Survey repeats it at redelivery. The difference between the two determines fuel consumed, and it is the figure both sides will rely on if the charter party is ever disputed.
