Off-Hire Bunker Survey – Container Vessel
This case study outlines an independent off-hire bunker quantity survey carried out at vessel redelivery. The assignment focused on verifying remaining fuel quantities onboard and supporting transparent settlement between contractual parties.
Overview
A container vessel was being redelivered at the end of a charter period. Accurate measurement of bunkers remaining onboard was required to calculate final fuel adjustments and avoid post-redelivery disputes.
Scope of Work
- Attendance onboard during redelivery
- Measurement of fuel and diesel tanks
- Verification of remaining onboard quantities
- Cross-check of vessel declarations
- Review of tank data and soundings
- Photographic documentation
- Preparation of independent survey report
Findings
Measured bunker quantities were within expected operating variance when compared with declared figures. All calculations and observations were documented in the final report.
Outcome
An independent off-hire bunker report was issued to the parties, providing a factual basis for final settlement and reducing the risk of bunker quantity disputes after re-delivery.
Frequently Asked Questions: Off-Hire Bunker Surveys
What is an off-hire bunker survey?
An off-hire bunker survey is a technical verification of the exact fuel quantities (VLSFO, LSMGO, etc.) remaining onboard at the moment a vessel is redelivered from the charterer back to the owner.
Why is an off-hire survey necessary for redelivery?
It provides an independent, third-party record of ROB (Remaining On Board) figures. This ensures that the final financial settlement between the contractual parties is based on technical facts, reducing the risk of disputes.
What does the PAMS survey process include?
Our surveyors conduct physical tank soundings, record temperatures, verify density through bunker delivery notes (BDNs), and apply trim/list corrections to provide a mathematically sound final quantity report.
How is the final report used?
The report serves as the official technical evidence for the redelivery certificate, enabling the owner and charterer to reconcile bunker costs accurately in the final hire statement.
Why are independent bunker surveys important?
Independent bunker surveys provide an objective verification of fuel quantities at delivery and redelivery. By using standardized measurement methods and documented calculations, they help prevent commercial disputes, improve transparency between contractual parties, and support accurate financial settlement.
