Bunker Quantity Survey

Our senior consultants conduct BQS to accurately determine the quantity of fuel oils onboard at the time of bunkering, delivery/redelivery, or prior to the commencement of a charter period. These surveys are crucial for ensuring compliance with charter party terms, preventing bunker disputes, and safeguarding against potential fuel theft or misreporting, and ensuring:

  • Charter party compliance: Verifies quantities to protect both owners and charterers
  • Dispute prevention: Creates a defensible record for claims involving fuel shortages or quality issues
  • Regulatory compliance: Ensures adherence to international fuel measurement and environmental standards
  • Evidentiary value: Accepted by courts, P&I Clubs, and insurers as legally valid documentation

Comprehensive Assessments & Reporting

Our certified marine consultants/engineers:

  • Measure and calculate quantities of HSFO, VLSFO, MGO, and other grades
  • Manually assess the bunker tanks by taking soundings and/or ullage measurements
  • Apply corrections for temperature, density, and trim/list
  • Record ROB (Remaining on Board) quantities with corrections
  • Supervise bunker delivery operations where applicable
  • Provide full documentation and certification in line with MARPOL and industry standards

We ensure every bunker survey is conducted transparently, accurately, and with full legal defensibility, compliance, ethics, and a strong code of conduct, giving you confidence and control over one of your most valuable voyage components.
