Offshore pipeline and subsea system reliability is crucial for the safe and efficient operation of oil and gas production facilities. Reliabilities mean that the pipeline and subsea system can perform their intended functions under specified conditions for a given period of time without failure. In this course, students learn to apply theories of reliability engineering to the analysis, interpretation and evaluation of common components with respect to the design, operation and maintenance stages of asset life cycle. The course provides an introduction to the concepts of reliability engineering including time-dependent failure mechanism, physics-of-failure mechanism, reliability measures and assessment for components and complex systems, maintainability and availability analysis. The course includes case studies of failure modelling, reliability assessment and risk analysis from systems and operations within the process, offshore oil and gas and renewable energy industries.
By the end of this Course the participant will be able to:
