It is well known that the growing of energetic needs and the dealing with always more severe environmental requirements, are constantly turning the world attention towards renewable energy sources. Among all, the attention is particularly growing towards the potential of the wind sector because, on the contrary to other renewably energy sources, wind power is plentiful. The main objective of this paper is to fix the basis and the methodologies for the performance-based design process of offshore wind turbines, using a systemic approach [1]. This objective becomes more important considering the fact that offshore wind turbine structures, necessitate advanced structural modelling and finite element analysis with a high level of accuracy [2]. Starting from the most recent studies as covered in the field literature [3] and on the basis of the established codes and standards [4,5], the aim is to approach the above mentioned topic by means of three subsequent steps: a. Structural System decomposition b. Structural Performance decomposition c. Choice of the analysis method for the assessment of any combination of Structural Component/Performance. The proposed framework has the potential to be of aid to the designers in the decision making concerning such complex structural systems.

Abstract
It is well known that the growing of energetic needs and the dealing with always more severe environmental requirements, are constantly turning the world attention towards renewable energy sources. Among all, the attention is particularly growing towards the potential of the wind sector because, on the contrary to other renewably energy sources, wind power is plentiful. The main objective of this paper is to fix the basis and the methodologies for the performance-based design process of offshore wind turbines, using a systemic approach [1]. This objective becomes more important considering the fact that offshore wind turbine structures, necessitate advanced structural modelling and finite element analysis with a high level of accuracy [2]. Starting from the most recent studies as covered in the field literature [3] and on the basis of the established codes and standards [4,5], the aim is to approach the above mentioned topic by means of three subsequent steps: a. Structural System decomposition b. Structural Performance decomposition c. Choice of the analysis method for the assessment of any combination of Structural Component/Performance. The proposed framework has the potential to be of aid to the designers in the decision making concerning such complex structural systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
