TFG Marine has continued its rollout of mass flow meter (MFM) technology across its US Gulf Coast bunker fleet, with two supply barges — Buffalo B414 and Buffalo B304 — fitted with the equipment.

Both vessels received ISO 22192 certification for their newly installed MFMs last month, according to the supplier. The international standard covers the use of MFMs in the bunkering process and is widely regarded as providing a basis for accurate and transparent fuel quantity measurement.

TFG Marine explained that the installations were part of an ongoing investment in technology and best practice across its global bunkering operations, forming part of a broader effort by its North America team to advance bunkering standards in the region.

The two barges are operated in collaboration with Buffalo Marine Service, which TFG Marine acknowledged for its “continued partnership and support”.

TFG Marine indicated that further news from its US Gulf Coast operations would be forthcoming "over the coming weeks".

As previously reported, TFG Marine announced the addition of an ISO 22192-compliant MFM aboard the Buffalo 404 — a barge on time charter from Buffalo Marine Service — back in July 2025, with the installation representing what TFG Marine claimed to be the first ISO-certified MFM-equipped bunkering barge operating in the US Gulf.

At the time, TFG Marine stated that it intended to equip close to 90 percent of its global bunkering fleet with MFMs by 2026.
