Abstract

A control and supply unit for an actuating device of a choke, a valve, a blow-out preventer or some other device applied in the field of oil and natural gas production. The control and supply unit includes an auxiliary power supply that is rechargeable and a connecting means to exchange data or supply a voltage. The unit is implemented separately from the actuating device and the connecting means is connected via a cable connection to a separate plug connection module arranged on the actuating device.

Claims

1. A retrievable choke insert assembly, comprising:

an actuating device; and

a control and supply unit for the actuating device, the control and supply unit comprising;

an auxiliary power supply that is rechargeable; and

a connector to exchange data or supply a voltage;

wherein the control and supply unit is implemented separately from the actuating device.

2. The control and supply unit according to claim 1, wherein the connector is connected via a cable connection to a separate plug connection module arranged on the actuating device.

3. The control and supply unit according to claim 2, wherein the plug connection module comprises a connection housing and at least one plug connection device.

4. The control and supply unit according to claim 3, wherein a coupling means for transmitting electric power or data is implemented between the connection housing and the actuating device.

5. The control and supply unit according to claim 3, wherein the connection housing is releasably secured to an outer side of a housing of the actuating device.

6. The control and supply unit according to claim 2, wherein the actuating device has power supplied thereto directly via the plug connection module.

7. The control and supply unit according to claim 2, wherein the plug connection module is configured to be connected to an external control module.

8. The control and supply unit according to claim 2, wherein the plug connection module is adapted to be connected to a remotely controllable vehicle.

9. The control and supply unit according to claim 2 further comprising a unit housing that comprises a communication interface, the auxiliary power supply, and a motor control unit.

10. The control and supply unit according to claim 9, wherein the communication interface comprises a CAN field bus.

11. The control and supply unit according to claim 9 wherein the communication interface comprises a field bus and the terminals of the field bus and the voltage supply are implemented separately.

12. The control and supply unit according to claim 9, wherein the communication interface and a voltage supply connection of the connector are formed on a supply and communication assembly.

13. The control and supply unit according to claim 12, wherein the supply and communication assembly comprises connections for supplying electric power to the motor control unit, the auxiliary power supply, or a sensor unit of the actuating device.

14. The control and supply unit according to claim 12, wherein the supply and communication assembly comprises bus connections for communication with or control of the auxiliary power supply, the motor control unit, or a sensor unit of the actuating device.

15. The control and supply unit according to claim 12, wherein the supply and communication assembly comprises a ground terminal connected to the auxiliary power supply or the motor control unit.

16. The control and supply unit according to claim 2, wherein the connecting means connector is configured to couple to a submarine control module for communication or voltage supply.

17. The control and supply unit according to claim 2, further comprising a plug connection module with two plug connection devices associated with the actuating device to provide redundancy.

18. The control and supply unit according to claim 2, wherein the plug connection module is configured for connection of a vehicle voltage supply line or a vehicle data line for supply with electric power by and for an exchange of data with the vehicle.

19. A control and supply unit for an actuating device of a choke, a valve, a blow-out preventer or a control device applied in the field of oil and natural gas production, the unit comprising:

an auxiliary power supply that is rechargeable;

a communication interface to exchange data; and

a voltage supply connection to supply a voltage;

wherein the control and supply unit is implemented separately from the actuating device.
