Abstract

A jacket type offshore structure from the North Sea is considered. The time variant reliability is estimated for failure defined as brittle fracture and crack through the tubular member walls. The stochastic modelling is described. The hot spot stress spectral moments as function of the stochastic variables are described using spline function response surfaces. A Laplace integral expansion is used to estimate the time variant reliability. Parameter studies are performed for the reliability estimates and the results of the time variant and the time invariant reliability analyses are compared. (Authors)
