This document explores the wave run-up loads on offshore monopile structures, particularly those experienced by the main access platforms during severe storms. Such incidents have been observed to cause significant damage, necessitating a deeper understanding and accurate prediction of these loads.
The main objective of this research is to compare various vertical wave run-up load models, focusing on their prediction accuracy and computational efficiency.
First the wave run-up heights and wave run-up loads of analytical models are compared to each other. These results are calculated with the maximum wave heights and water depths on the Dogger Bank. It can be seen that the wave run-up heights and therefore the wave run-up loads are unrealistically high. The main reason for this is that the analytical models are used outside the boundaries where they are validated for. This leads to less reliable results.
Theoretical and numerical limitations are in this thesis to increase the reliability of the results.
