Abstract
In this study, 60 deterministic offshore pile design cases for typical ranges of the pile properties and tension loading as well as typical soil conditions for the North Sea were compared with reliability-based designs regarding the corresponding failure probability, where typical soil variability and model errors were assumed for the stochastic subsoil model. On the basis of a new calibration approach, quality factors for each design method with respect to the most likely outcome regarding the failure probability were derived. With the so-obtained quality factors, an enhanced evaluation of each deterministic design method as well as the safety level in terms of the required global safety factor is possible.
