The Maritime Administration (MARAD) released a first-of-its-kind, public database that chronicles U.S.-flagged, privately owned domestic articulated tug-barge (ATB) and integrated tug-barge (ITB) vessels.  

The United States leads the world in the number of ATBs operated, which provide a cost-competitive alternative to tankers in the domestic energy market.  Unlike a typical tug and barge combination, an ATB/ITB is mechanically linked, combining the economics of tug and barge operations with the speed, maneuverability, sea-keeping capability, and heavy weather-reliability similar to that of a self-propelled tanker.  ATBs can also be built in less time than conventional tankers, and offer improved operating efficiencies at a lower capital cost. 

In the report, MARAD has cataloged over 130 tug-barge units in service with a carrying capacity of 15.2 million barrels.  The intention of this report is to calculate and illustrate the scale and scope of this unique segment of the maritime industry.
