Marine cranes operate in the demanding and ever changing dynamic environment imposed by the sea. Some of the most severe loads occur when the crane is ship mounted and is on/off loading an adjacent barge or ship. The wave induced relative motion between the crane and the load, as the load leaves the barge platform, can produce severe dynamic stresses in the crane boom. The lifting line can become slack and then suddenly taut. But even with a continuous load in the hoist line, just the transfer of load from the moving platform to the crane will produce oscillations in the load. It is these oscillations which are treated in this paper.
