1. A system under control of an operator for cleaning waste material, or sludge, having a solid phase and a liquid phase from a container comprising:
- (a) a source of cleaning fluid for supply to a directionally controllable nozzle carried by;
(b) a remotely controllable movable robotic vehicle, said vehicle being controllable from outside a direct line of sight of an operator, said movable robotic vehicle capable of directing a stream of said cleaning fluid onto said waste material in an amount sufficient to cause a flow of at least a portion thereof; and
(c) said vehicle having an evacuation nozzle and hose capable of evacuating at least a portion of said liquid phase and said flow of said waste material exteriorly to said container.

Abstract
Methods and apparatus are disclosed for cleaning storage containers used in petrochemical or oil refineries. A remotely controllable dual tracked robotic vehicle is placed in a container to be cleaned. A cleaning fluid diluent material is directed against waste material in the container causing a portion of it to form a slurry which is vacuumed out by a nozzle and hose carried by the vehicle. A separator system exterior to the tank processes the removed slurry.

6. A remotely controllable movable robotic vehicle sized and adapted for passage in a storage tank containing waste sludge to be removed, comprising:
-
a) dual hydraulically powered tracks separately powered and remotely controllable and attached to either side of a vehicle body platform; b) cannon nozzle means for directing flow of a cleaning fluid in a desired direction; c) video camera means attached to said nozzle for remotely observing the effect of said directed flow of cleaning fluid on said sludge; d) controllable light source means for illuminating the region generally of the direction of flow of said cleaning fluid; and e) evacuation nozzle means attached to said vehicle and remotely controllable and movable therewith to pick up and remove a pumpable slurry of said sludge and said cleaning fluid from the storage tank. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
