What characteristic defines an Integrated Tug and Barge (ITB)?

An Integrated Tug and Barge (ITB) is primarily defined by the design that allows it to operate as a single rigid unit. This is achieved through a specialized coupling system that connects the tug and the barge. This connection provides enhanced maneuverability and stability, making it effective for navigating challenging waterways. The rigid interface means that the forces experienced during operation are distributed more evenly, which enhances the overall operational efficiency and safety of the ITB system.

The design allows the tug to push or pull the barge effectively, enabling it to handle significant cargo loads while maintaining good control over the entire unit. This integration reduces the risks associated with traditional tow configurations, where the tug and barge are separate entities. Consequently, the ITB configuration is favored for its ability to perform in various maritime environments while maximizing cargo capacity and operational efficiency.
