The Probability of an Offshore Accident

Risk is the product of frequency and consequence. Accordingly, high consequence events which occur infrequently may contribute as much risk as frequent events which have smaller consequences. Estimating the frequency with which events occur is as important to overall risk as accurately predicting the consequences. One way of estimating frequency is to look at historical records. The information presented below are an abstract from the “Safety of offshore oil & gas Impact Assessment Annex I” working paper from the European Commission, published in 2011 to accompany the proposal for a regulation of the European Parliament on safety of offshore oil and gas prospection, exploration and production activities.

Reliability Theory of Structures

The marine industry can improve its performance in designing systems, subsystems and components on which its operations depend on by using risk-based methods and tools. In an environment of increasingly complex engineering systems and structures, the concern about the operational safety of the latter continues to play an important role in their design, construction and operation procedures. A rational and quantitative approach for assessing the failure probabilities and the impact of failure of the structure on its environment (human beings, natural environment) is needed. [Read more…]
