ExxonMobil is the first accredited bunker fuel supplier to introduce a mass flow metering system (MFMS) in Singapore and Hong Kong. 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
