“…This can be attained by the hydrostatic head of the drilling fluid or the combination of applied surface backpressure and the hydrostatic head of the drilling fluid (managed pressure drilling-MPD scenario). As a secondary barrier during drilling, the blowout preventer (BOP) is designed to close the well annulus or the drill pipe (Cai et al 2012). In deepwater and ultradeepwater drilling operations, the BOP is latched onto a wellhead, situated on the seabed (Huse and Alme 2013).…”

“…The configuration of the stack is dependent on the expected operations, redundancy, flexibility and the trade-off between the advantages and disadvantages of each configuration (Januarilham 2012). Besides the annular preventers, ram preventers, connectors and other components such as the flexible joint, choke/kill valves and choke/kill lines are integrated to form the whole subsea BOP stack (Cai et al 2012). There are several types of rams which have different tasks in addition to sealing the well.…”

In order to avoid mistakes and to save a great deal of time in analysis, an innovative methodology was developed that can analyze the well operations and rig characteristics involved to define the best emergency disconnect sequence (EDS) available. A solution was developed based on the characteristics of the rigs and blowout preventers (BOPs), and six variables were considered that directly affect the choice of EDS. All possible combinations of 64 scenarios were analyzed, and the priority of choice of the EDS was defined empirically. This paper presents an approach to EDS risk management and examples of exposure time (time without riser safety margin and shear capability) for the same well, which can be lowered from 13% to 0.1%. The impact of this reduction is related to the ability of the BOP to cut some of the heavy casings, in addition to improved availability of EDS modes. This implementation opened up many possibilities for the performance of risk exposure analysis, enabling comparison of several BOP configurations of contracted rigs and selection of the best options. This innovative approach allowed a better management of the rig schedules, prioritizing safety aspects and making it possible to allocate the fleet in a systematic way.

“…In order to overcome the limitations of FTA and FMEA methods, many methods have been employed to research the reliability of subsea BOP system. Cai et al, [7] present a Markov model of subsea BOP stack and research the effects of stack configurations and mounting types. Reliability of control system of subsea BOP system is also studied using Bayesian networks [8].…”

Safety-critical systems are designed to prevent catastrophic consequences from failure, such as injury or death to humans and environmental damage. These must be carefully designed to ensure reliability requirements. The purpose of this paper is to identify the number of models in the reliability analysis of safety-critical systems. To achieve this goal, we conducted a systematic review of 40 shortlisted studies. The selected studies are classified based on various techniques used in safety-critical systems. This paper summarizes the literature review in the field of reliability of safety-critical systems. The limitations of the literature are exquisitely represented. The international safety norms and applications of safety-critical systems are discussed systematically in this paper. This paper emerges research trends, research challenges and insights of the researcher for future research direction in the area of safety-critical systems.
