A DBN-based risk assessment model for prediction and diagnosis of offshore drilling incidents
Wu, Shengnan; Zhang, Laibin; Zheng, Wenpei; Liu, Yiliu; Lundteigen, Mary Ann (Journal article; Preprint, 2016)Drilling operations of offshore oil and gas fields are characterized by high technical complexity, high risks, and high costs, since they are always in harsh environments with complicated geological factors. Lost circulation ... -

Performance analysis for subsea blind shear ram preventers subject to testing strategies
Wu, Shengnan; Zhang, Laibin; Barros, Anne; Zheng, Wenpei; Liu, Yiliu (Journal article; Peer reviewed, 2018)In a subsea blowout preventer system, a subsea blind shear ram preventer (BSRP) plays as a crucial safety barrier by cutting off the drill pipe and sealing the wellhead to prevent serious accidents. Testing and repairs of ... -
Reliability assessment for final elements of SISs with time dependent failures
Wu, Shengnan; Zhang, Laibin; Lundteigen, Mary Ann; Liu, Yiliu; Zheng, Wenpei (Journal article, 2018)Reliability assessment for safety-instrumented systems (SISs) plays a vital role in improving the design of SISs. Traditional methods for SIS reliability assessment that assume constant failure rates are, however, not ... -
Reliability assessment for subsea HIPPS valves with partial stroke testing
Wu, Shengnan; Zhang, Laibin; Liu, S; Liu, Yiliu; Barros, Anne Cecile Pénélope; Lundteigen, Mary Ann (Chapter, 2017)High integrity pressure protection systems (HIPPS) have been applied in subsea applications to prevent accidents due to over-pressurization. A subsea HIPPS can be regarded as a complete functional loop consisting of sensors, ... -
Reliability modeling of subsea SISs partial testing subject to delayed restoration
Wu, Shengnan; Zhang, Laibin; Zheng, Wenpei; Liu, Yiliu; Lundteigen, Mary Ann (Journal article; Peer reviewed, 2019)Subsea oil and gas production has always involved the challenging task of determining the overall reliability of safeguarding systems, such as safety instrumented systems (SISs). Partial testing and delayed restoration of ... -
Risk identification of third-party damage on oil and gas pipelines through the Bayesian network
Guo, Xiaoyang; Zhang, Laibin; Liang, Wei; Haugen, Stein (Journal article, 2018)This paper aims to identify the risks influencing oil and gas (O&G) pipeline safety caused by third-party damage (TPD). After comprehensive literature study, we found that the traditional risk identification of TPD suffers ...
