CIVINS / The use of wind power is in a period of rapid growth worldwide and wind energy systems have emerged as a promising technology for utilizing offshore wind resources for the large scale generation of electricity Drawing upon the maturity of wind turbine and floater technologies developed by the wind energy and oil and gas industries, respectively, large offshore wind energy systems have been developed and are being proposed for operation in offshore areas where environmental restrictions are less restrictive, large wind resources exist, and open sea areas are available for wind farm development. A fully coupled dynamic analysis/technique was developed to predict the response of a floating wind turbine system in a stochastic wind and wave environment This technique incorporated both non-linear wave loading on the submerged floater and the aerodynamic loading on the wind turbine A tension leg spar buoy was designed to support the wind turbine This design was chosen due to its relatively small size and hence lower potential cost per wind turbine The system's tethers were attached to the ends of spokes which radiated out from the spar cylinder This arrangement of lines and spokes promised to be very stiff in the roll and pitch modes of motion.

Abstract This thesis has been done in Barcelona, Spain, in cooperation with the University of Gävle (HiG) and the Universitat Politècnica de Catalunya (UPC). At UPC there is a project carried out where the goal is to analyze the characteristics and performance of the wind turbine IT-100, with an intention to optimize it. This is carried out by assignment of Engineers Without Borders and Practical Action. The purpose of the thesis has been to present what power, value of tension and current the turbine will produce in different wind velocities.   The IT-100 is built to generate electricity to the population in the countryside in, among other countries, Peru. The energy the turbine captures from the wind will be used to charge vehicle batteries that are used in the households as a source of electricity. This is an effective, cheap and environmental-friendly way of supplying households with electricity.   The idea of using the energy in the wind has been known for thousands of years. It started with simple windmills for grinding grain and later more complicated machines like wind turbines were created. Wind power is one of the worlds cleanest sources of energy with as good as no emissions at all while in running.   The result of the work with this thesis work is an Excel file where the, by the purpose requested, parameters are presented in relation to different wind velocities. With some conditions set from the start, some known values of reference and the rotor blades rotational speed as a key variable, these parameters were possible to calculate.   During the work, the project came upon some difficulties such as; not enough information about the wind turbine, too little previous knowledge among the students and trouble with the Spanish language. However, on the whole the project has been successful and a good learning experience.
