Structural Reliability Analysis (SRA) is a tool for calculating failure probabilities of a structure that takes into account all random variables involved in ship structural design and provides a better and alternative to deterministic approaches. With a number of different regulations based on structural reliability theory already existent for quite some time now in the areas of Civil and Aeronautical engineering and the Nuclear Power industry it has been only a matter of time before the ship/offshore field implemented such procedure into its regulatory regime. Classification Societies have published since the early 1990s suggestions of how reliability analysis techniques can be used to analyse structures and recently some have incorporated and accepted those (Bureau Veritas 2000) as an equivalent means of analyzing structures to supplement their existing regulations.
