Fuzzy fault tree analysis of oil and gas leakage in subsea production systems
Journal of Ocean Engineering and Science, 2018 This paper presents a probabilistic failure analysis of leakage of the oil and gas in a subsea production system using fault tree analysis (FTA). A fault tree was constructed by considering four major areas where the leakages can be initiated. These are:

Assessment of gas and dust explosion in coal mines by means of fuzzy fault tree analysis
International Journal of Mining Science and Technology, 2018 During the past decade, coal dust and gas explosions have been the most two serious types of disasters in China, threatening the lives of miners and causing significant losses in terms of national property. In this paper, an evaluation model of coal dust

Methodology for computer aided fuzzy fault tree analysis [PDF]
Process Safety and Environmental Protection, 2009 Process facilities are well known for unplanned chemical emission, toxic release, fire and explosion and operational disruption. These incidents have the potential to cause an industrial accident and environmental damage. From the investigation of all major accidents, it is apparent that most industrial accidents can be avoided or restricted with a ...

Ontology-Based Fault Tree Analysis Algorithms in a Fuzzy Environment for Autonomous Ships
IEEE Access, 2021 This study deals with fault tree analysis algorithms based on an ontology-based approach in a fuzzy environment. We extend fuzzy fault tree analysis by embedding ontology-based fault tree structures. The ontology-based approach allows conducting advanced
