Abstract: A system includes a top drive including a handling ring assembly including a main body, a main shaft that traverses the main body of the handling ring assembly. an internal blowout preventer (IBOP) valve, wherein the main shaft engages the IBOP valve. a two-piece actuator sleeve assembly including a non-rotating portion and a rotating portion, at least one hydraulic cylinder connected to the main body of the handling ring assembly, wherein the at least one hydraulic cylinder actuates the two-piece actuator sleeve assembly, and left and right hand crank assemblies having left and right wireless encoders connected thereto, wherein the crank assemblies with the wireless encoders are attached to, and are configured to rotate with, the IBOP valve along with the rotating portion of the two-piece actuator sleeve assembly.

Abstract: A direct drive drawworks having a first electric motor comprising a first output shaft, a second electric motor comprising a second output shaft, and a drum for storing a flexible line. The drum may be disposed between the first electric motor and the second electric motor. The first output shaft and the second output shaft may each be connected to the drum. The first electric motor and the second electric motor may be collectively operable to rotate the drum. The first output shaft and the second output shaft may be connected to the drum such that the drum rotates at the same speed as the first output shaft and the second output shaft.

Abstract: A system includes a first transmission having a first planetary gearset, a first drive shaft, and a first annular sleeve. The first annular sleeve is positioned circumferentially about the first drive shaft, and the first annular sleeve is configured to move axially relative to the first drive shaft and the first planetary gearset from a first axial position in which the first annular sleeve engages a first sun gear of the first planetary gearset to a second axial position in which the first annular sleeve engages a first ring gear of the first planetary gearset to adjust a gear ratio of the first transmission.

Abstract: A drawworks system for a mineral extraction system includes a drum mounted on a drum shaft and configured to support a cable. The system also includes a gearbox assembly having a gearbox housing, a gearbox supported by the gearbox housing and having a gearbox input shaft and a gearbox output shaft, wherein the gearbox input shaft is configured to be coupled to at least one motor and the gearbox output shaft is coupled to the drum shaft to drive rotation of the drum shaft and the drum, and a brake supported by the gearbox housing and coupled to the drum shaft to block rotation of the drum shaft and the drum, wherein the gearbox and the brake are positioned on one side of the drum along an axial axis of the drawworks system.

Abstract: A drawworks gearbox includes additional braking on the input side of the gearbox to provide a redundant emergency brake and, optionally, a separate parking brake with the drum-side brakes being the emergency brake. An air-cooled brake disc is attached to a high speed coupling connected to the gearbox input pinion. A hydraulic-apply, spring-release brake is mounted to the gearbox housing at each pinion location and arranged to act on its respective disc.
