Independent bunker surveys
Bunker Quantity Survey & marine fuel inspection
Your reliable partner for impartial quantity determination of marine fuels across the Netherlands, Belgium and Germany.
Welcome to Global Maritime Survey
Impartial measurements you can build on
We offer a complete service for bunker deliveries. Our experienced bunker surveyors carry out quantity inspections and provide impartial, independent quantity determinations of marine fuels, whether the delivery is gauged manually or metered with a Mass Flow Meter (MFM).
We produce detailed reports confirming the delivery and noting any shortfalls, check the Bunker Delivery Note (BDN) for completeness, and support you in drafting a Letter of Protest (LoP) where needed.

How we work
From preparation to report
- 1
Preparation & sampling
We set up the sampling equipment to ISO 13739 and collect the sample correctly, either as a manual drip sample at the manifold or via the MFM installation.
- 2
Requisition
Before starting, the receiving vessel signs the requisition, confirming the quantity, quality and required pumping rate.
- 3
Controlled transfer
Bunkering starts slowly to check for leaks, speeds up for optimal transfer and slows down towards completion.
- 4
Final measurement & reporting
We take a final measurement on both vessels, calculate the exact quantity, check the BDN and thoroughly investigate any discrepancies.
