Abstract
A buoyant barge mounted crane has a vertical tower with a horizontal gantry. On the gantry is a cargo transfer assembly including a trolley and lift mechanism. A balance load is mounted on one end of the gantry, and the opposite end of the gantry is connected by a cable to a floating counterweight barge. As the trolley travels horizontally on the gantry, the counterweight barge maintains equilibrium of the crane through the transfer of weight through the cable.
