ABSTRACT:
A dredging apparatus including a spud barge and a dredging barge. A hollow pivot sleeve is located at the stern of the dredging barge. A hydraulically extendable arm is mounted on the spud barge and is pivotally connected to the pivot sleeve. A large diameter bull ring is affixed to the pivot sleeve. A pair of cables connect to the bull ring and to a pair of power driven winches on the spud barge. The winding and unwinding of the cables around their winches swings the dredging barge about the pivot sleeve during dredging. An anchor spud extends through the hollow pivot sleeve to hold the dredging barge in fixed position when the spud barge is being relocated.
