| Abstract:In order to effectively improve the reliability of fire and gas safety shutdown and the crew safety in the drilling ship, aiming at the high complexity of process control and safety cut-off control strategy of drilling ship instrument and control system, which is difficult to pass the ordinary instrument test, the distributed control system with network redundancy and the safety instrument system of drilling ship built with safety level safety controller were developed. A semi physical simulation platform was built to verify the accuracy of the control logic. The verification results show that:the process control and safety system control strategy and shutdown strategy of the drilling ship instrument control system prototype are safe and effective, the functions of wireless communication and management software, report analysis, trend prediction and other functions match the requirements of the real ship. The simulation platform can not only optimize the control effect, but also improve the test efficiency. |
