ABSTRACT:
A method and apparatus for removing mud from around and inside of a casing is shown and described. Examples of such casings include piles of offshore oil production platforms. In accordance with a preferred embodiment of the present invention, a submersible pump having a propeller and coupled to several nozzles is lowered to a position adjacent the mud to be removed. A volume of water is forced through the nozzles against the mud, the action of which, together with the propeller, serves to dilute and break up the mud. The submersible pump then forces the mud and water upward through a flexible tube to be discharged into open water.
