摘要： The disclosure relates to a method for preventing damage to a multiphase pump, comprising measuring the differential pressure of a fluid across a multiphase pump over a time period and measuring the axial position of a rotor of the multiphase pump over a time period. The method also involves calculating a pressure fluctuation by measuring the difference between a maximum value of the measured differential pressure and a minimum value of the measured differential pressure over the time period and calculating a dynamic axial position by measuring the difference between a maximum value of the axial position of the rotor and a minimum value of the axial position of the rotor over the time period. Also involved in the method is comparing the calculated pressure fluctuation of the multiphase pump with an expected pressure fluctuation value, and comparing the calculated dynamic axial position of the rotor with an expected dynamic axial position value, and selecting an operating condition of the multiphase pump from one of expected operation, surge operation and choke operation based on the comparison between the calculated pressure fluctuation and the expected pressure fluctuation value, and the comparison of the calculated dynamic axial position and the expected axial position value.

摘要： Method and apparatus for controlling a subsea actuator, particularly controlling at least two subsea actuators associated with a wellhead. The method comprises controlling the subsea actuators with a single subsea control unit. A mechanical output is provided and mechanical drive is transferred to the actuator/s, such as via a mechanical connector. The actuator can control a valve, such as to selectively open or close access to a bore below a Xmas tree associated with a hydrocarbon wellbore.

摘要： A subsea well equipment landing body (1) comprising an indicator assembly to indicate landing of the landing body or to indicate locking of the landing body. The indicator assembly has a stem bore (7), a sliding stem (11) within the stem bore that has a stem head (23) protruding beyond an external face of the landing body. A stem channel (25) in the sliding stem extends between the stem head and a stem channel mouth (27), and is in fluid communication with the outside of the landing body. A hydraulic channel (9) in the landing body is in fluid communication with the stem bore. The stem channel mouth is positionable in a communicating position, in which there is fluid communication between the hydraulic channel and the stem channel, and a non-communicating position, without fluid communication between the hydraulic channel and the stem channel.
