Abstract
This paper discusses the design and implementation of an extremely reliable system to remotely monitor and control the subsea blowout preventer (BOP) stack by using triple modular redundancy technique. The system hardware architecture including surface component and subsea component are proposed. The control logics, human machine interface (HMI) graphical design and redundant databases are development by using off-the-shelf software. An experiment of subsea BOP control is performed in the laboratory. The results show that the system can give correct alarms when mistakes occur, and all subsea BOP functions can be performed correctly.
