- Geotechnical Seminar Series 2015 - Foundations for Offshore Wind Turbines by Dr.-Ing. Ercan Taşan Brandenburg Univ. of Tech. Cottbus–Senftenberg Germany 30 March, 2015 Monday 10:30 - 12:00 at K1 Conference Room Abstract Foundations for offshore wind turbines, jackets, monopiles, tripods and suction buckets, are subjected to high cyclic loads arising from the action of wind and water waves. These loads can lead to an accumulation of permanent soil deformations and excess pore water pressures in water saturated soils. A new practical design method for cyclic laterally loaded pile foundations in water saturated sands with considering these accumulation effects is formulated. A possible pore water pressure accumulation around the pile is evaluated on the basis of the three‐dimensional fully coupled two‐phase finite element analysis. The design approach has been validated using the results from the physical pile model tests. In addition, interesting ongoing and completed projects in the North Sea and the Baltic Sea will be reported and the themes for further research will be identified. Background of Dr. Taşan Dr. Taşan graduated with a B.S. degree in Civil Engineering from Technical University of Berlin in 2004. Between 2005 and 2011 he was research associate at the Institute of soil mechanics and foundation engineering at TU Berlin. In 2011 he completed his PhD thesis on “On the monopile foundations design of offshore wind energy converters” at TU Berlin. Since 2012 he is the Chief executive officer of TRADYNA GmbH, working on offshore wind farms, and since 2014 he is a professor of Geotechnical Engineering at Brandenburg University of Technology Cottbus–Senftenberg, and Head of Institute for Soil Mechanics and Foundations / Geotechnics.
