Background
Published in Jie Zhang, Chuanjun Han, Rubber Structures in Oil and Gas Equipment, 2022
A blowout preventer (BOP) is one of the core equipment for the well control operation, which can ensure the safe and normal operation of oil and gas drilling engineering. In drilling operation, when the liquid column pressure in the well is less than the formation pressure, blowout may occurs. The blowout preventer can quickly close the wellhead to prevent blowout accidents. While, the blowout preventer also plays an important role in underbalanced drilling, pressure operation and other processes [20]. The blowout preventer failure causes serious environment pollution and life threatening. The rubber core is one of the key components of the blowout preventer. The rubber core performance determines the sealing performance of the blowout preventer and the oil and gas exploitation progress.

Safety and reliability analysis for butterfly valves in the offshore oil and gas industry
Published in Safety and Reliability, 2022
In the past studies, the topic of safety and reliability assurance of industrial valves has been addressed. A previous study examined the effects of partial stroke testing on the reliability of safety critical valves (Lundteigen & Rausand, 2007). Safety critical valves include emergency shut-down (ESD) and process shut-down (XSV) valves which are connected to process shutdown (PSD) systems. Additionally, subsurface safety valves (SSVs) are installed in the well. In the event of an abnormal condition in the well, such as an over-pressure scenario, they must be closed to prevent blowout. An analysis of the reliability of SSVs has been a popular research topic (Colombo et al., 2020; Molnes et al., 1992; Rausand & Vatn, 1998). Another study explored the reliability of pressure relief valves that are installed on piping and mechanical equipment to release over-pressure gases or fluids (Gross, 2008). Recently, several studies have examined the use of online monitoring and strict factory acceptance tests (FATs) to enhance the safety and reliability of valves in the offshore oil and gas industry (Sotoodeh, 2021c, 2021e). The FAT includes different series of tests, primarily pressure tests, that are applied to each valve and actuator after final assembly and before shipment (American Petroleum Institute, 2017). The online monitoring method known as ValveWatch, which includes various sensors, has been in use for almost two decades. With this system, the possibility of failures of valves, actuators and control systems can be detected while the safety critical valves are in operation without the need to shut down the entire plant. The system can also be used to detect problems without shutting down the entire plant (Jeeves, 2016; Juvik et al., 2002; Lemme & Furseth, 2019; Sangolt et al., 2019; Sotoodeh, 2021c). A couple of safety analysis methods are described in the following paragraph for the industrial valves used in the oil and gas industry.
