Diepeveen, N.F.B. Jarquin Laguna, A. Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2011-11-29 Abstract The Delft Offshore Turbine (DOT) project is a research project within DUWIND. The main objective of the project is to reduce the costs of offshore wind energy through technical solutions. A defining characteristic of the DOT concept is the fluid power transmission. The next step for the DOT concept is to make a full preliminary design. A helpful tool to assist in this process of making a full scale preliminary design is to run experiments with a small scale prototype of the fluid power transmission, the MicroDOT. The aim of the MicroDOT project is to design and construct a fluid power transmission prototype of approximately 10kW. The focus of this paper is the design process of the prototype. During the design process the best options for the main components within the trans- mission are selected first. Then the components are sized such that the wind turbine rotor operates at its optimal tip speed ratio. This is where the rotor extracts energy from the wind most efficiently. Finally, a dynamic response analysis is carried out by making a model of the transmission design. The results from this analysis show that the damping of the system is very large. Even when the transmission is excited at its natural frequencies no problems are expected with the transmission, due to this large damping.
