Part of the Springer Series in Reliability Engineering book series (RELIABILITY)


This chapter is devoted to the reliability analysis of offshore structures. It contains seven sections. The first section describes uncertainties in general and gives information about the reliability methods. The second section presents basic definitions and structural reliability methods in more detail. Calculation of the reliability index β by the FORM and SORM methods are explained for nonlinear failure functions of non-Normal correlated design variables in general. The calculation algorithms and flow diagrams are presented. Then, the numerical integration (NI) and Monte Carlo simulation (MCS) techniques of the Level-III (exact) reliability methods are summarized. The third section presents the inverse reliability method and its calculation algorithm. The fourth section describes uncertainties in the spectral stresses and fatigue damages of offshore structures, which arise from different origins. The fifth section formulates stress spectrum and spectral moments in a reduced uncertainty space. The sixth section explains the fatigue reliability calculation of offshore structures and provides calculation algorithms. The seventh section demonstrates the reliability calculations.
