摘要：

This paper performs reliability evaluation of the subsea annular blowout preventer (BOP) based on stochastic Petri nets. The presented model has been analyzed based on its isomorphic continuous time Markov chain. According to the derived equations, transient availability, reliability and MTTF of the annular BOP are obtained. Availability will reach a stable value very quickly while reliability decreases slowly over time. The effects of failure rates on MTTF are researched. The results demonstrate that in order to effectively improve MTTF, great efforts should be made to reduce the failure rates of blue pod or yellow pod. © 2013 SERSC.
