Reliability 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 کاملReliability 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...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولReliability Analysis of Multiplex Control System of Subsea Blowout Preventer Based on Stochastic Petri Net
Original scientific paper The multiplex (MUX) control system of subsea blowout preventer (BOP) plays a vital role in providing safe working conditions for the subsea drilling activities. According to the working states and critical failure modes of the MUX control system, this paper presents its stochastic Petri nets (SPN) model, taking into account the imperfect fault detection capacity. The n...
