Dr.-Ing. Marc Seidel

Principal Engineer Siemens Gamesa

I am working in wind energy since 1996 - first as researcher at University of Hannover, later in the wind industry as design engineer for support structures (towers, substructures & foundations) of wind turbines on- and offshore. Today I have specialized in Offshore Wind Turbines, with a focus on structural design and load simulations. I have worked on several offshore wind projects, with all kinds of substructures (e.g. jackets, monopiles, gravity base) and at very different locations (extremely shallow water to 50m water depth). I am also a member of national and international standardizations committees (like IEC 61400-3 or German BSH and DIBt) and member of several supervisory panels for research projects in Germany. I have published a number of papers on my work, see http://www.marc-seidel.de where you can find PDF copies of most of my publications. Specialties: Engineering, Research & Development
