Marine fuel supplier TFG Marine has installed mass flow meters (MFMs) on two additional bunker supply barges operating in the US Gulf Coast, according to Ship & Bunker.
The barges, identified as Buffalo B414 and Buffalo B304, have received ISO 22192 certification for their newly fitted MFMs, TFG Marine said in a LinkedIn post cited by Ship & Bunker. ISO 22192 is the international standard governing the certification of mass flow metering systems used in marine fuel delivery.
What MFMs Do
Mass flow meters are designed to improve the accuracy of bunker quantity measurements during fuel transfers. According to Ship & Bunker, the technology is intended to give customers greater confidence in the volumes of fuel actually delivered to their vessels.
Part of a Wider Rollout
The two new installations form part of TFG Marine’s continued expansion of MFM technology across its bunkering fleet in the US Gulf Coast region, Ship & Bunker reports.
This rollout follows TFG Marine’s announcement in May of the previous year regarding the expansion of its physical supply operations along the US Gulf Coast. Shortly after that announcement, the company fitted an MFM on its first barge in the region, according to the report.
Does This Matter to You?
Accuracy in bunker fuel quantity measurement is a recurring concern for vessel operators, charterers, and bunker traders, as discrepancies between ordered and delivered fuel volumes can lead to commercial disputes. The continued adoption of mass flow meters, as reported by Ship & Bunker, reflects an ongoing industry shift toward metering technology that aims to reduce such disputes by providing more precise measurement during transfer.
For those bunkering vessels in the US Gulf Coast region specifically, TFG Marine’s expanding MFM-equipped barge fleet may be a relevant factor when considering fuel quality and quantity assurance during supply operations in that area. The source material does not detail how many barges in TFG Marine’s fleet remain without MFMs, nor does it specify further plans beyond the current installations.
