mass flow metering system

Mass flow metering system (MFMS)

Contact an expert

ExxonMobil is the first accredited bunker fuel supplier to introduce a mass flow metering system (MFMS) in Singapore and Hong Kong, as well as one of the first to introduce a MFMS for marine gas oil (MGO) in Singapore. MFMS technology automatically monitors the mass flow, density and temperature throughout the bunker fuel delivery process.

ExxonMobil’s MFMS provides:

  • Increased transparency – reducing the uncertainties associated with density, temperature and other factors like tank geometry. A MFMS is accurate to within +/- 0.5 percent
  • Significant cost benefits – saving an estimated US $2,000* per fuel delivery by eliminating the possibility of human calculation errors from traditional tank dipping
  • Significant time savings – offering the potential to save up to three hours per delivery**
  • Enhanced system integrity – with independent certification of the calibration and security of the system's associated pipelines, valves, gauges and barge equipment. Tamper-evident seals are also installed throughout
  • Increased traceability – with data logged throughout the entire delivery process, illustrating the fuel mass transferred at any point in time, offering a transparent and accurate measure of delivered fuel

How to ensure transparency when bunkering marine fuel
 
ExxonMobil has implemented Mass Flow Metering Systems (MFMS) onboard its bunkering barges in the Amsterdam-Rotterdam-Antwerp (ARA) ports as well as in France, Singapore and Hong Kong. They are fully accredited and certified by an independent third party, ensuring transparent marine fuel bunkering.
Our advice to vessel operators remains the same: ask your fuel suppliers what they are doing to enhance bunker transparency.

Mass flow metering

One of the first suppliers to launch a MFMS for MGO in Singapore

Learn how ExxonMobil launched the system ahead of The Maritime and Port Authority of Singapore’s (MPA) mandate that all distillates must be delivered by MFMS from July 1, 2019.

*Per 1,000MT stem size delivery at $300/MT. Includes surveyor costs, temperature delivery range and density delivery range but does not include dip tank measurement errors. A temperature measurement delta of 10°C amounts for up to US $2,100. A 3kg/m3 density difference amounts for up to US $1,000. These variables can be avoided by the use of a secure mass flow metering system, therefore negating the need of a quantity surveyor with an estimated cost of up to US $2,000.
