Dynamic Bayesian networks based performance evaluation of subsea blowout preventers in presence of imperfect repair

作者：

Highlights：

• 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.
