A thrust magnetic bearing integrated with an induction machine and methods for using the same for slow roll control of rotors and other rotating components is provided. The rotor can include a shaft and a thrust bearing disk. The thrust magnetic bearing can include thrust bearing stators positioned axially adjacent to the thrust bearing disk and they can be configured to apply axial magnetic forces to the thrust bearing disk. The induction machine can be configured to generate a rotating magnetic field that causes a torque to be applied to the thrust bearing disk in a predetermined rotational direction. In one aspect, the induction machine can include a radial stator positioned adjacent to a circumference of the thrust bearing disk and two or more circumferentially offset windings. In another aspect, the induction machine can position the two or more circumferentially offset windings on the thrust bearing stators.

Thrust active magnetic bearing for shaft slow roll control

A controller for a rotary machine includes a processor and a memory coupled to the processor. The memory is configured to store operating modes of the controller. The operating modes include a normal operating mode and a fault tolerant operating mode. The controller is configured to receive a signal from at least one sensor and determine an operating state of the rotary machine based on the signal. The controller is also configured to switch the operating modes based on the determined operating state of the rotary machine and regulate at least one electromagnetic bearing and at least one flow control device. The controller is further configured to adjust at least one of the at least one electromagnetic bearing and the at least one flow control device in the fault tolerant operating mode.

A fluid transport system includes at least one flow control device and a multiphase pump configured to transport fluid. At least one pump sensing device is configured to measure at least one operating characteristic of the multiphase pump. A controller is programmed with a pump map including a correlation of the at least one operating characteristic of the multiphase pump with at least one operating characteristic of the fluid. The controller is configured to determine an estimated value of the at least one operating characteristic of the fluid based on the measured value of the at least one operating characteristic of the multiphase pump and the pump map. At least one regulating device coupled to at least one flow control device is modulated based on the estimated value of the at least one operating characteristic of the fluid.

System and method for controlling a fluid transport system

A method of detecting a vibration node between a non-collocated sensor-actuator pair of a rotatable component includes applying an excitation signal to an actuator of the sensor actuator pair. The method also includes obtaining frequency response data from the sensor-actuator pair. The method further includes analyzing the frequency response data to ascertain a resonant frequency of the rotatable component. The method includes identifying a resonance/anti-resonance peak pair in the frequency response data for the non-collocated sensor-actuator pair. Furthermore, the method includes determining whether the vibration node is located between a sensor and the actuator of the non-collocated sensor-actuator pair based on the resonance/anti-resonance peak pair.

A gas engine assembly includes a compressor, a combustion system, a bypass line and a control system. The control system is configured to control gas supply parameters based on a transportation delay value. The transportation delay value corresponds to a delay between a time when a gas supply control mechanism is adjusted and a time that gas having a corresponding adjustment of a gas characteristic is received at a predetermined point downstream from the gas supply control mechanism.

Gas dosage control for gas engine

A subsea fluid processing system is provided containing a liquid reservoir, an inlet tank, a pump, an outlet system, and a fluid re-circulation loop. The liquid reservoir circulates a primer liquid stream to the inlet tank via the fluid re-circulation loop. The inlet tank further receives a first production fluid stream and mixes it with the primer liquid stream to produce thereby a second production fluid stream having a reduced gas volume fraction (GVF) relative to the first production fluid stream. The pump receives the second production fluid stream from the inlet tank and increases its pressure. Further, the outlet system containing the liquid reservoir receives the second production fluid stream from the pump and separates at least a portion of the primer liquid stream from a principal production stream. The primer liquid includes at least one exogenous liquid not derived from the first production fluid stream.
