ExxonMobil has introduced the first independently accredited mass flow metering system (MFMS) in Hong Kong, following the introduction of the system in Singapore.

According to ExxonMobil, the fuel delivery system [pictured] can help save vessel operators both time and money when refuelling whilst also providing increased transparency and efficiency to the bunkering process.

The Hong Kong MFMS has been accredited by Lloyd's Register, in partnership with A*STAR's National Metrology Centre, the national measurement institute of Singapore, and Metcore International Pte Ltd, a consultancy with expertise in MFMS for bunkering.

The technology directly measures fuel mass instead of volume, in line with industry best practice guidelines, to provide a prompt and accurate measurement reading for vessel operators. The seals used are also validated by independent parties to prevent any misuse of the system.

ExxonMobil says its MFMS provides multiple benefits for vessel operators, suppliers and regulatory bodies, including enhanced accuracy when compared to typical tank dipping - within +/- 0.5 per cent - increased efficiency by measuring fuel mass, and reduced uncertainties related to variables including density and temperature.

ExxonMobil also calculates that it can save an estimated US$5,000 (based on a 1,000-tonne delivery at a cost of $300 per tonne), up to three hours per delivery when compared to manual tank dipping, and improve transparency as measurement data is logged throughout the process.

Following accreditation by Lloyd's Register, the MFMS has been installed on the time-chartered bunker vessel Anshing, to deliver ISO 8217:2012 bunker fuel grades RMG 380 and RMK 500.

"The expansion of ExxonMobil's accredited mass flow metering system capability will help to ensure buyers receive the fuel they pay for," said Deepankar Banerjee, Asia Pacific marine fuels sales manager. "ExxonMobil continues to lead the industry in the implementation of mass flow metering systems, bringing an accredited system to Hong Kong after its success in Singapore."

The launch of an accredited MFMS in Hong Kong follows its introduction in Singapore, where ExxonMobil achieved a number of industry firsts: the first to market with a Maritime and Port Authority (MPA)-approved MFMS, the first to guarantee delivery via a MFMS, and the first to deliver more than one million metric tonnes via a MFMS. Today, all ExxonMobil fuel deliveries in Singapore are supplied by barges equipped with its MPA-certified MFMS.

Lloyd's Register's Douglas Raitt, regional consultancy manager, commented: "Getting bunkering right is more important than ever. The introduction of this technology is evidence of ExxonMobil's commitment to industry innovation. The use of mass flow metering systems when bunkering fuel is a significant improvement, ensuring compliance. Buyers now have peace of mind that they are receiving the correct quantity of fuel for which they are paying."
