The response treatment of structural systems subject to stochastic loading requires the mathematical modeling of the input load, propagation such as input through the systems, and the treatment of uncertainty inherent in the output using probabilistic methods. For jackup structures, the input load from the wave is modeled using the significant wave height and wave period which are statistical averages obtained from long term studies. The variability in the determination of these wave parameters leads to further uncertainty in the response output. This study, therefore, investigated the sensitivity of these wave parameters to the timedependent reliability of jack-up. The wave was modeled using Karhunen-Loeve representation, and the propagation of uncertainty was performed on a simplified jack-up model using Duhamel convolution integral. The response analysis was performed using VanMarckes timedependent solution method. The results of jack-up survival probability obtained for different failure criteria in deck displacement show that the probability is more sensitive to the wave period than the wave significant height.
