Abstract: The present disclosure provides a system and method articulating and rotary spray system for fluids that includes a first drive for rotating a mast for different headings and a second drive for rotating a nozzle for different pitches at any time with or without rotation of the mast. The method and system uses a system of interacting gears that rotate a control rod in variable synchronization to control the nozzle pitch relative to the mast heading while the control rod orbits about a center of rotation of the rotating mast along a longitudinal axis.

Abstract: The present disclosure provides a cooling system and method for a reciprocating mandrel in a blowout preventer test system that provides coolant to the mandrel through a majority of its stroke. The system includes an inner coolant tube and an outer coolant tube, with both tubes inserted into a mandrel inner bore. The inner coolant tube is fixed in position on a base and not attached to the mandrel. The outer coolant tube is fixed in position and attached to the mandrel. The outer coolant tube slidably and optionally sealingly engages the inner coolant tube throughout the mandrel stroke. Coolant can flow through the base, upward through an inner volume of the inner coolant tube, and into an inner volume of the outer coolant tube and out of coolant openings in the outer coolant tube to flow on the inner bore surfaces of the mandrel to cool the mandrel.

Abstract: The present disclosure provides a system and method for a cleaning apparatus that includes a swash assembly for allowing independent control of the nozzle pitch from the nozzle rotation, and further includes supplying a cleaning fluid through the same apparatus used to rotate the nozzle. The method and system allows cleaning with spray patterns of substantially 360 degrees spherical ranges of motion. The nozzle angle can be controlled by hydraulic cylinders that can reversibly translate a rack along a longitudinal axis of a nozzle assembly to engage a pitch gear coupled to the nozzle. The system is automatically resettable to a default position upon failure of hydraulic pressure. Generally, a plurality of nozzles are used to balance the side forces on the main mast. A remote control system allows an operator to design and control an optimal cleaning procedure, and to adjust the nozzle rotation, angle, and cleaning regime.
