A test system and a method for testing a multiplexed BOP control system () wherein the multiplexed BOP control system () comprises a first and a second redundant central control unit () with respective first and second operator consoles (), wherein the central control units () are arranged for being connected via a first signal transmission system () to respective first and second redundant subsea control systems () arranged for being connected to BOP valves () and BOP sensors () in a subsea BOP (), and the test system comprises a control system signal simulator () arranged for being connected between one or more of the control units () and one or more of the subsea control systems (), and further arranged for entirely or partly replacing the first signal transmission system () and providing simulated signals () between one or more of the control units () and one or more of the subsea control systems ().

Method and system for testing a multiplexed BOP control system

A system for testing a vessel control system includes sensors on board the vessel to send one or more sensor signals over a signal line to the control system; command input devices on board the vessel to send one or more of desired position, course, velocity, etc. over a command signal line to the control system; an algorithm in the control system to compute control signals to based on sensor data, communication lines for sending of one or more simulated signals and/or simulated command signals from a remote test laboratory to the control system; and a simulator including an algorithm for the simulation of the new dynamic state of a vessel model based on a previous state, the control signals, and the dynamic parameters of the vessel. The control system continues to compute the control signals to achieve at least one of desired position, course, velocity, etc. based on real and/or simulated sensor signals and real and/or simulated command signals.

System and method for testing a control system of a marine vessel

A system for testing a control system in a vessel, comprising: sensors on board the vessel; command input devices on board the vessel to send desired position, course, velocity; an algorithm in the control system for the computation of control signals to the vessel actuators; communication lines for sending simulated command signals from a remote test laboratory to the control system; a simulator including an algorithm for the simulation of the new dynamic state of a vessel model based on a previous state; where the communication line is arranged for sending back the new simulated stare of the vessel model in the form of simulated sensor signals for continued computation to achieve desired position, course, velocity; and where the communication line is sending the response from the control system to the remote test laboratory.
