摘要： A micro grid for an oil field is powered by a utility power grid. A micro grid controller is adapted to prevent excessive or unstable power draw on the utility power grid while allowing uninterrupted power supply for drilling rigs in the oil field. The micro grid controller is adapted to control operation of one or more pieces of electrical equipment on the drilling rigs. The micro grid controller may prioritize operation of the electrical equipment based on relative priority of the operations or based on an operating condition of the drilling rig.

摘要： A predictive landing failsafe system is adapted to slow or stop a permanent magnet AC motor in response to a selected condition, such as a power outage. In some embodiments, the predictive landing failsafe system may short two or more terminals of the AC motor in response to the selected condition. In some embodiments, one or more resistors may be coupled between the two or more terminals, the resistors lowering the short-circuit current and thus making a more smooth stop for the AC motor. In some embodiments, the AC motor may be used in a drawworks.

摘要： An electric motor having internal closed loop cooling includes a cooling chamber coupled to the stator cover of the electric motor. A fan is positioned to circulate air through the interior of the electric motor and the cooling chamber. A heat sink in the cooling chamber removes heat from the circulating air. The heat sink may be coupled to a fluid cooling jacket to transfer heat thereto or therefrom.

摘要： A tubular joint elevator includes a ringed portion configured to lift a tubular joint. The elevator includes an elevating mechanism disposed adjacent to the ringed portion, and configured to elevate the tubular joint. In some embodiments, the elevator includes first, second, and third doors. The elevator includes a first locking member, and the first door includes a first locking recess. The first locking member is axially displaceable between an advanced position and a retracted position such that it is either received in or separated from the first locking recess. The third door includes a locking pin, and the first door comprises a locking hole. The third door is longitudinally displaceable between a first position and a second position such that the locking pin is either separated from, or received in, the locking hole. Methods of using the same are also included.

摘要： An apparatus includes a thrust bearing adapted to engage a tubular component. A bearing carrier is connected to the thrust bearing, an arm is connected to the bearing carrier, and an actuator is connected to the arm. In one embodiment, the bearing carrier includes an arcuate notch through which the tubular component is adapted to extend. In another embodiment, the apparatus has a first configuration in which a vertical offset is defined between the tubular component and the thrust bearing, and a second configuration in which the thrust bearing is engaged with the tubular component for the support thereof. In another embodiment, the apparatus is placed in the first configuration in response to a cessation of a supply of electrical power to a control valve in fluid communication with the actuator. In another embodiment, the tubular component is connected to, or is part of, a quill of a top drive.
