Reliability Research of Software System for Subsea Blowout Preventers
In order to meet a high reliability requirement of subsea drilling, a redundant software system for subsea Blowout Preventers (BOP), including control logics, HMI programs, remote access and redundant databases are developed. The Bayesian networks for control logics, HMI programs and redundant databases are built and then the whole Bayesian networks are established. The quantitative reliability...
متن کاملApplication of Bayesian Networks to Reliability Evaluation of Software System for Subsea Blowout Preventers
The work develops a redundant software system for subsea blowout preventers, including control logics, human-machine interface (HMI) programs, remote access and redundant databases in order to meet the high reliability requirement of subsea drilling. The Bayesian networks (BN) for control logics, HMI programs and redundant databases are built and then the whole BN are established. The quantitat...
متن کاملDynamic Bayesian networks based performance evaluation of subsea blowout preventers in presence of imperfect repair
This paper presents a quantitative reliability and availability evaluation method for subsea blowout preventer (BOP) system by translating fault tree (FT) into dynamic Bayesian networks (DBN) directly, taking account of imperfect repair. The FTs of series system and parallel system are translated into Bayesian networks, and extended to DBN subsequently. The multi-state degraded system is used t...
متن کاملReliability Analysis of the Electrical Control System of Subsea Blowout Preventers Using Markov Models
Reliability analysis of the electrical control system of a subsea blowout preventer (BOP) stack is carried out based on Markov method. For the subsea BOP electrical control system used in the current work, the 3-2-1-0 and 3-2-0 input voting schemes are available. The effects of the voting schemes on system performance are evaluated based on Markov models. In addition, the effects of failure rat...
متن کاملA Redundant FPGA Based Controller for Subsea Blowout Preventer Stack
A redundant Field Programmable Gate Array (FPGA) based controller for subsea Blowout Preventer (BOP) is presented. Triple modular redundancy technique is used for architecture design, since high reliability is a necessary requirement for subsea BOP control system. A multiprocessor system is developed to enhance reliability of the processors and performance of the system. In addition, the shared...
