Abstract
By designing mainly axially loaded offshore foundation piles in North Sea conditions, two commonly used design methods, the β-method and the ICP-method, were used. Thereby the required minimum embedded pile length may vary a lot. The actual safety which is achieved with a certain pile length and the corresponding prescribed partial safety factors is not known. For general assumed pile and soil conditions it could be determined that a reliability index between β = 3.5 and β = 4.1 is established. Further it could be shown that the prescribed partial safety factors should be decreased for the β-method, where an increase for the ICP-method should be considered. By performing reliability based design also a more accurate determination of the required pile length for a specified safety is possible.
