Publication number: 20250188808Abstract: A method of handling a short tubular on a drilling rig. The drilling rig includes a drill floor, a short tubular storage apparatus on which a short tubular is arranged, a vehicle which moves and transports the short tubular storage apparatus on the drill floor, and a tube handling apparatus having a base supported by the drill floor, an arm with a first end pivotally mounted on the base and a second end on which a pick up tool is mounted, and an actuator which pivots the arm relative to the base. The pick up tool holds the short tubular. The method includes using the vehicle to transport the short tubular storage apparatus to a location on the drill floor, and operating the actuator to move the pick up tool to engage the short tubular, to lift the short tubular, and to move the short tubular on the drill floor.Type: ApplicationFiled: January 21, 2025Publication date: June 12, 2025Applicant: MHWIRTH ASInventors: GEIR LIEN, PETTER MYDLAND

Patent number: 12241316Abstract: 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.Type: GrantFiled: June 22, 2023Date of Patent: March 4, 2025Assignee: MHWIRTH ASInventors: Geir Lien, Petter Mydland

Publication number: 20230003103Abstract: 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.Type: ApplicationFiled: March 12, 2021Publication date: January 5, 2023Applicant: MHWIRTH ASInventors: PETTER MYDLAND, GEIR LIEN, NICOLAI NILSEN, ERLAND NYJORDET
