About the course

Risk has become a key concept in modern society. Growing concern about the environment and a number of disasters have served to focus attention on the hazards and risks involved in a wide range of activities from offshore oil production to rail and air transport; from the design of football stadia to the operation of chemical plants and environmental protection. Today there is a wide range of techniques available to assess risk and reliability, both in relation to safety and in the wider sense. These techniques now underpin new legislation on safety and have relevance over a broad spectrum of activities, including environmental and other systems, where risk and reliability are key concerns.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Acquire a basic knowledge of the concept of risk and its application in the offshore industry
  • Carryout reliability analysis techniques and the mathematical basis of risk and reliability
  • Apply reliability block diagrams, fault tree and event trees analysis to the assessment of an underwater system
  • Identify the role of human error and equipment failure in accident causation
