A new design concept of Blowout Preventer for decision support
Lee, Shenae; Lundteigen, Mary Ann; Paltrinieri, Nicola; Liu, Yiliu; Rød, Magne; Dale, John (Chapter, 2017)The Blowout Preventer (BOP) system is used for controlling blowout risks in drilling operations. The system is implemented to shut down an oil and gas well when the well fluids have entered the wellbore. All BOP systems ... -
A systems engineering–based approach for framing reliability, availability, and maintainability: A case study for subsea design
Zhang, Juntao; Haskins, Cecilia; Liu, Yiliu; Lundteigen, Mary Ann (Journal article; Peer reviewed, 2018)Framing reliability, availability and maintainability (RAM) aspects are critical for an engineering design, as RAM is concerned with the sustained capability of a system throughout its useful life. RAM analysts are responsible ... -
Analytic Assessment of Safety Instrumented Systems Operating in High-Demand Mode
Taiwo, Solomon Ademola (Master thesis, 2015)The pervasive presence of safety instrumented systems in the process industry indicate the growing need for reliable loss prevention to the minutest degree. The backdrop towards addressing this need is by drawing up a ... -
Application of Digital Twins in Condition-Based Maintenance
Yang, Chao; Cai, Baoping; Shao, Xiaoyan; Liu, Yonghong; Liu, Yiliu; Feng, Qiang; Liu, Guijie; Wang, Honghui (Chapter, 2021)Condition-based Maintenance (CBM) is a combination of fault diagnosis, fault prognosis, and maintenance decisions. The diagnostic results can be used to predict the remaining life and maintenance plans are made based on ... -
Applications of machine learning, in reliability analysis, as an alternative to traditional survival models
Ahmedov, Ahmed (Master thesis, 2020)Bruken av pålitelighets og levetidsdata, i operasjonsfasene av industrielle systemer, har økt de siste årene ettersom det kan betydelig redusere kostnader innenfor sikkerhet og vedlikehold. Dette har ført til en utvikling ... -
Availability Assessment of Electrically-Operated Blowout Preventers
