ABSTRACT:
An apparatus for interconnecting a pair of barges, or other waterborne vessels, to facilitate hookup and release of barges in an "on-hip" arrangement with a powered vessel. Oriented on the bow of each barge, coincident with the barge's longitudinal center line, is a bracket terminating in a socket. A pivot shaft with an upper ball adapted to fit in the socket is provided with a lower trunion to support a bridge element whereby two barges may be connected. The bridge element is free to rotate in a horizontal plane about the pivot shafts to allow swinging movement of the barges and the ball-in-socket fitting allows a limited range of independent movement for the barges such as in swells. Movement limiting fenders and chains are provided to control swing of the barges. Such an apparatus allows a single tug or dredge to rapidly make up a dual barge push towing arrangement.
