Bop control systems and related methods

A blowout preventer (BOP) control system comprising:

• a system controller configured to actuate a first BOP function by communicating one or more commands to one or more nodes of a functional pathway selected from one or more functional pathways associated with the first BOP function;
• each node comprising an actuatable component configured to actuate in response to a command received from the system controller, each node having:
• one or more sensors configured to capture at least two sensed values during actuation of the component;
• and
• a processor configured to:
• receive the at least two sensed valves from at least one of the one or more nodes;
• obtain an expected value of a model based on at least one of the at least two sensed values;
• compare the expected value to the other of the at least two sensed values to obtain a difference between the two values;
• and
• communicate to the system controller one or more of the following:
• (i) a fault if the difference between the two values exceeds a threshold;
• (ii) a useful life remaining of the actuatable component based at least on the difference between the two values;
• (iii) a risk level based at least on the difference between the two values;
• or
• (iv) the difference between the two values.

A blowout preventer (BOP) control system comprising:

• a system controller configured to actuate a first BOP function by communicating one or more commands to one or more nodes of a functional pathway selected from one or more available functional pathways associated with the first BOP function;
• each node comprising an actuatable component configured to actuate in response to a command received from the system controller, each node having:
• one or more sensors configured to capture a first data set during an actuation of the component;
• and
• a processor configured to:
• adjust one or more coefficients of a model such that the adjusted model approximates one or more values from the first data set;
• and
• communicate to the system controller data based at least on at least one of the one or more coefficients of the adjusted model.

A method for actuating a first blowout preventer (BOP) function, the method comprising:

• selecting a first functional pathway from two or more available functional pathways associated with the first BOP function;
• communicating one or more commands to an actuatable component of each of one or more nodes of the first functional pathway to actuate the component, where actuation of the component of each of the one or more nodes of the first functional pathway actuates the first BOP function;
• and
• receiving, from at least one of the one or more nodes of the first functional pathway, information associated with actuation of the component.
