Bunkering ports around the world have long used a variety of small tankers or tug and barge combinations to deliver fuel to visiting ships. Mostly this was heavy oil, but recently a new breed of bunkering vessels is emerging to deliver clean burning liquefied natural gas (LNG) to modern ships with dual-fuel capabilities.The fall of 2020 will see a new addition to this fleet servicing ships in Florida and the Caribbean. As an articulated tug barge (ATB) combination, the vessel will have a cargo capacity of 4,000 cubic meters of LNG.
