Abstract: A method for controlling drilling operations includes defining operation zones in a drilling operation area, each operation zone having equipment operating therein, and repeatedly performing the steps of: determining a position of at least one person in the drilling operation area, determining whether the respective determined position is within any of the operation zones and associating each person to the operation zone in which the person is located, determining whether the respective determined position is within a safety zone in proximity to the equipment, determining at least one action to be performed with regard to each operation zone in which the person has been determined to be present, and transmitting at least one control signal for controlling the drilling operations based on the at least one action determined. The at least one action is determined dependent on whether or not the position of the person is in the safety zone.

Abstract: A drilling rig system includes a drilling rig having a floor which is generally planar, and a utility vehicle having a base, a drive apparatus, and a ground engaging motive apparatus upon which the base is supported on the floor. The drive apparatus drives the ground engaging motive apparatus to move the utility vehicle across the floor. The ground engaging motive apparatus is drivable so as to change a direction of travel of the utility vehicle at any point on the floor.

Abstract: A cleaning apparatus for cleaning a drill string. The cleaning apparatus includes a base, an arm, a fluid flow conduit, and a motor. The base supports the arm on a drill floor of a drilling rig. The arm has a first end which is mounted on the base, a second end at which a spray nozzle is arranged, and at least one articulated joint via which the arm, or a portion of the arm, can pivot relative to the base. The fluid flow conduit is connected to the spray nozzle so that a pressurized fluid entering the fluid flow conduit can spray out of the spray nozzle. The motor pivots the arm about the at least one articulated joint so as to alter an orientation of the spray nozzle relative to the base.
