Abstract: A system for cleaning a container may include: a fluid source; an arm that moves a nozzle in at least two directions; a fluid retrieval device; a separator; and a fluid mover. One method for cleaning includes securing an arm to a support positioned at least partially outside of the container; spraying a fluid onto an inner surface of the container using the nozzle; drawing the fluid and an entrained material out of the container using the fluid retrieval device; removing at least some of the entrained material from the fluid using the separator; and conveying the fluid from the separator to the nozzle using the fluid mover. The arm and/or the fluid retrieval device may be remotely installed.

Abstract: A system for handling drill cuttings conveys cuttings slurry into bulk tanks via a conduit. The bulk tanks have an un-pressurized interior volume that receives the slurry. A conveyance member positioned inside the bulk tank forces the slurry out of a discharge port at the bottom of the bulk tank. One suitable conveyance member is a screw-type conveyor coupled to a motor that applies a vertical motive force to the slurry. The bulk tanks hold the cuttings slurry until it can be discharged via the discharge port to a transport vessel for processing or disposal. For offshore operations, the system includes a separation unit on the rig that forms the cuttings slurry from fluid returning from the wellbore and a cuttings flow unit that conveys the slurry effluent from the separation unit to the bulk tanks. In one arrangement, a controller and sensors control the flow of slurry into the bulk tanks.

Abstract: The disclosed modular filter may include a filter medium and an external frame structure. The filter medium may form a chamber having a front side, a back side, and a periphery. The filter medium may also have a plurality of fibers. The external frame structure has at least one aperture mounted on at least one of the front side and back side of the chamber in which the external frame structure has a thickness greater than the lengths of the plurality of fibers.
