A self-contained floating vessel is configured as a self-propelled or barge-like floating hull. It is equipped with a vacuum exhaust unit configured to pull an air-stream vacuum, by means of pipe and hose lines, from ship cargo holds which contain residual particulate cargo. Primary and secondary collectors are used to separate the particulate cargo from the air-stream. The air-stream with particulate cargo is separated in the first collector by a series of baffles. Approximately ninety-five percent of the residual cargo drops to the bottom of and accumulates within the primary collector, where it is recovered through a dump valve in the collector. The remaining air-stream/particulate cargo mixture is pulled through the secondary collector, which filters and recovers the particulate from the air-stream by means of filters. The cargo particulate is also accumulated in the secondary collector, where it is recovered through a dump valve. The collectors can function within the hull of the self-contained vessel or can be separated from the hull and transported by floating crane or alternate ship or shoreside lifting devices and placed on recovery receptacles, such as cargo bays, cargo barges or positioned over jumbo cargo bays. After the cargo is removed, the vessel cargo holds are washed down to remove traces of cargo, so as to permit loading of new cargo. The waste water is pumped through filters to remove the trace cargo. The filtered water can then be pumped into the ship's ballast tanks or, depending on the cargo, pumped directly overboard.
