An apparatus for controlling a subsea blowout preventor (BOP) includes a control system for controlling a subsea BOP of a subsea stack assembly installed over a subsea oil and gas well. The control system includes a first topside control device and a second topside control device, and a first subsea control device and a second subsea control device. The first topside control device, the second topside control device, the first subsea control device, and the second subsea control device are each communicatively connected with the BOP and operable to control operation of the BOP. The first subsea control device is a portion of a first control pod of the subsea stack assembly. The second subsea control device is a portion of a second control pod of the subsea stack assembly. The first topside control device is communicatively connected with the second topside control device via a ring communication network.

Communication networks for BOP control

A method can include generating a graphical user interface that includes vector graphics representations of equipment of a system for well operations, a data graphic for rendering sensor data of the system, and a graphical control actuatable to issue a control instruction for control of the system, where the system includes an uninterruptible power supply (UPS) and a blowout preventer (BOP), and where the UPS is selectively, operatively coupled to one or more electric actuators for changing a state of the BOP; responsive to operation of the system, receiving sensor data; and updating the data graphic based at least in part on the sensor data.

Well equipment system framework

A method includes actuating a blow-out preventer (BOP) by moving a ram using an electric motor. The method also includes capturing sensor data with one or more sensors as the BOP is electrically-actuated. The method also includes determining one or more parameters with a controller based upon the sensor data. The method also includes controlling the electric motor based upon the one or more parameters.

Electrically-actuated blow-out preventer

A drilling system includes a surface system comprising a control panel. The drilling system further includes a pressure control equipment configured to be operatively coupled to the control panel, wherein the control panel comprises at least one intrusion prevention system (IPS) enabled device configured to provide for one or more IPS functions.

Security system and method for pressure control equipment

A closing unit system for a blowout preventer (BOP) stack includes a first fluid reservoir, a first power source, a first pump system fluidly coupled to the first fluid reservoir and electrically coupled to the first power source, and a valve manifold fluidly coupled to the first pump system via a closing unit hose assembly and configured to couple to the BOP stack. The closing unit system also includes one or more processors that are configured to receive an input indicative of an instruction to adjust an actuator associated with the BOP stack, and instruct the first power source to provide power to the first pump system to cause the first pump system to pump a fluid from the first fluid reservoir to the valve manifold in response to the input.

Closing unit system for a blowout preventer

A drilling rig includes a rig component, an actuator coupled to the rig component, an electric power storage device coupled to the actuator and configured to cause the actuator to actuate. The actuator, by actuating, may perform a safety function in the rig component. The rig also includes a renewable power generator coupled to the electric power storage device and configured to supply at least some of the electric current to the electric power storage device that is supplied to the actuator.
