Dynamic Bayesian networks based performance evaluation of subsea blowout preventers in presence of imperfect repair
The reliability and availability of subsea BOP system are evaluated. The fault tree is translated into dynamic Bayesian network directly. The imperfect repair is modeled using multi-state degraded system. The imperfect repair cannot degrade the system performances significantly. Eight basic events contribute much to subsea BOP system failure.
