ABSTRACT:
An electro-magnetic coupling apparatus for use with a tug and barge tow includes a bumper frame which is pivotally carried by the tug. The bumper frame includes a bearing surface that is positioned to bear against the barge so that a load transfer between the tug and the barge occurs at the bearing surface. A magnetic coupling preferably in the form of a plurality of coil members is carried at the load transfer surface for developing a magnetic field which can form a connection between the barge and the tug. An electrical power source is carried by the tug for energizing the magnetic field and a powered guide comprising a powered sheave and a pair of lines extending from the sheave to the barge defines a steering mechanism for angling the bumper frame and tug with respect to each other when maneuvering to each barge while making up a tow of several barges, for example.
