This work's main focus is the analysis of the dynamics of floating offshore wind turbines. Starting from a model of floating platform realized on Simulink, is operated an extension from three to six degrees of freedom, allowing a variable wave direction also. After realizing CAD models of the floater to obtain all the inertia properties, an hydrodynamic simulation of the floating platform is performed, to obtain the characteristic parameters. A stability analysis of the model is performed, before converting it into C++ programming language to allow the interaction with external softwares. The source code is edited to make the user able to change the simulation parameters, and after compiled in form of a C++ library with the creation of a communication interface between the model and QBlade provided by the TU Berlin, used for the simulation of wind turbines, using a C++ class.
