Abstract
A system includes one or more processors configured to provide one or more control signals to cause supply of electric power from a power supply to one or more electric actuators. The one or more electric actuators are configured to adjust one or more components of a cable pressure control equipment (PCE) stack.
Claims14
A system, comprising:
- one or more processors configured to provide one or more control signals to cause supply of electric power from a power supply to one or more electric actuators that are configured to adjust one or more components of a cable pressure control equipment (PCE) stack,
- wherein a first control signal of the one or more control signals instructs supply of the electric power to a stuffing box actuator of the one or more electric actuators to adjust a packing material of a stuffing box of the one or more components,
- wherein a second control signal of the one or more control signals instructs supply of the electric power to a winch actuator of the one or more electric actuators to adjust a rate of rotation of a drum of a winch of the one or more components, and
- wherein a third control signal of the one or more control signals instructs supply of the electric power to a valve actuator of the one or more electric actuators to adjust a ram of a valve of the one or more components.

A system, comprising:
- one or more processors configured to provide one or more control signals to cause supply of electric power from a power supply to one or more electric actuators that are configured to adjust one or more components of a cable pressure control equipment (PCE) stack,
- wherein the one or more processors are configured to receive a leak signal from a leak sensor, determine whether a leak is present based on the leak signal, and provide a stuffing box control signal of the one or more control signals to supply the electric power to a stuffing box actuator of the one or more electric actuators to adjust a packing material of a stuffing box in response to determining that the leak is present.
A method, comprising:
- generating, using one or more processors, one or more control signals to cause supply of electric power from a power supply to one or more electric actuators that are configured to adjust one or more components of a cable pressure control equipment (PCE) stack;
- generating, using the one or more processors, a first control signal of the one or more control signals to cause supply of the electric power to a stuffing box actuator of the one or more actuators to adjust a packing material of a stuffing box of the one or more components;
- generating, using the one or more processors, a second control signal of the one or more control signals to cause supply of the electric power to a winch actuator of the one or more actuators to adjust a rate of rotation of a drum of a winch of the one or more components;
- and
- generating, using the one or more processors, a third control signal of the one or more control signals to cause supply of electric power to a valve actuator of the one or more actuators to adjust a ram of a valve of the one or more components.
