Application of Petri nets to performance evaluation of subsea blowout preventer system. (January 2015) - Liu, Zengkai
Abstract: This paper presents an application of deterministic and stochastic Petri nets (DSPN) to evaluate the performance of subsea blowout preventer (BOP) system. The overall subsea BOP system is comprised of five mechanical subsystems and five electrical subsystems, which can be viewed as a series-parallel system. In regard to common cause failures, TimeNET 4.0 toolkit is utilized to develop and analyze the DSPN models. Availability and reliability of the subsea BOP system and its subsystems are obtained. Besides, the effects of failure rate and repair time of each component on system performance are researched. Highlights: DSPN models are developed for performance evaluation of the subsea BOP system. Common cause failures are considered when developing the models. The effects of failure rates and repair time on system performance are studied.
