Often used for assault landings, if there was no harbor, a bulldozer or tank could tow the barge onto the beachhead, so supplies would be available to the Troops.

Barges were also used for ship-to-ship transfers and as a way to unload ships quickly, then move by a tugboat, also called a Sea mule.

Designed to carry products which require substantial preventive measures to ensure no uncontrolled release of cargo to the water or atmosphere, but only if the release does not constitute a long term hazard.

Designed to transport products classed as minor hazards, thus needing less degree of control.
