Bunker Quantity Survey
Independent verification for accurate fuel delivery
Fuel is one of the most valuable commodities onboard a vessel—and often the source of costly disputes. Our Bunker Quantity Surveys (BQS) are designed to provide an independent, accurate verification of the quantities of fuel delivered or received during bunkering operations.
At JM Marine Surveys, we act in the best interest of our clients—whether shipowners, charterers, or operators—by overseeing the entire bunkering process. From initial gauge readings to final soundings, we ensure full transparency and detect any irregularities that may indicate fuel loss, misdelivery, or malpractice.
Why Trust the Inspection to a Team of Professionals?
Only an experienced and qualified Bunker Quantity and Surveyor can provide complete information about the total amount of fuel and overall vessel performance.
There are several reasons to trust professionals:
- Use of modern equipment and innovative technologies for proper inspection. To ensure a high degree of accuracy in all measurements, proven and working methods are additionally applied.
- Minimal risk of disputes and disagreements regarding fuel quantity. This is achieved through properly formatted reports and maintenance of all documentation, which will contain useful and important information to protect the client’s business relationships with their partners.
- Global coverage in service provision. Clients can use specialist services in the world’s largest ports: for example, Rotterdam, Amsterdam, Antwerpen. Thus, inspection services can be ordered in different cities and countries where your vessel is located.
In the course of our work, our team fully adheres to all necessary international standards, uses advanced practices, and therefore the conducted operations will definitely comply with current regulatory requirements.
