Risk, reliability and safety (B3)

Venue: University of Strathclyde

Staff: Dr Evangelos Boulougouris, Professor N Barltrop

Aims: To provide an understanding of the concepts of risk, reliability and safety and associated current practice and regulation. To develop analytical skills in quantitative calculations associated with reliability and risk assessments.

Module Content: The module will combine formal lectures and tutorials with design and analysis case studies.

  • Review of probability and statistics underpinning risk and reliability.
  • Concepts of risk and hazard, perception, societal values and ALARP.
  • Formal methods of risk identification, quantification and consequence assessment; mitigation and management of risks.
  • Marine hazards: capsize, collision, fire & explosion, structural failures. Fault trees, event trees and decision trees.
  • Legislation and Safety Cases in offshore engineering and shipping.
  • Systems reliability: the bathtub curve, reliability data and Weibull models; series and parallel systems and networks.
  • Availability, maintainability and risk-based inspection strategies.
  • Design for availability and reliability.
  • Engineering of safety systems.

Structural reliability: concepts of capability, demand and safety indices; calculations using FOSM and Monte Carlo simulation; extreme value distributions and environmental load modelling; structural safety assessment.

Case studies will include - design of an automatic fire fighting system to meet a target availability, structural reliability assessment of a corroded flowline, formal safety assessment for a ferry.

Learning outcomes: Students will have an understanding of the concepts of risk and safety and their application in the marine context. They will be able to undertake qualitative and quantitative risk assessments, formal safety assessments, and reliability calculations for straightforward marine systems.
