Abstract

The design of offshore foundation piles regarding the compressive bearing capacity is normally done by applying the well known API “Main Text” method and CPT-based design methods, like the ICP-, UWA-, Fugro- and NGI-method. However, in practice a strong deviation regarding the required embedded pile length within these design methods has to be faced. In this study 50 deterministic pile designs were compared with reliability based designs regarding the corresponding failure probability. Based on a new calibration approach, where the most likely failure probability is determined, quality factors were obtained for each design method. 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 partial safety factor is possible. Altogether, it can be stated that the UWA-method is the most robust method for the considered boundary conditions in comparison to the other design methods.
