INTRODUCTION:

This paper will overview impact and vibratory-driven open-ended steel piles in saturated, non-cohesive soil conditions. Initially, the general advantages and disadvantages of the two installation methods will be pointed out. As the most important parameter, the pile’s ultimate bearing capacity after installation will be presented in detail by model and full-scale test results. The feasibility of vibrating large diameter steel piles into very dense soil conditions will be shown by the results from the installation of 30 Monopiles at the offshore wind farm Riffgat. General results will be summarized and discussed.
