Abstract

Renewable energy source use has been widely adopted in the world, it can be seen that wind energy is mostly preferred over other renewable energy sources. The analysis, design and construction of platform structures are the sets of tasks in search for natural sources of energy faced by engineering profession. Here a prototype wind turbine with platform and pile structure suitable for urban use is designed. This project focuses on analysis of offshore platform as supporting structure for 7MW (Mega Watt) offshore wind turbine for deep water applications. In this paper the offshore wind turbine, platform and pile foundation are separately modelled using CATIA software and imported in ANSYS and analysed separately with various wind speed .the maximum and minimum total deformation , equivalent stress and equivalent strain obtained are described detail in this paper with the maximum stress, strain and deformation for different wind speed values obtained for turbine, pile and platform are plotted in graph to show the variations obtained to understand the behaviour of wind. the manual calculations are done to design the platform and pile using IS code to check shear, deflection and to design reinforcement with proper load calculation. In this offshore platform we are using grade 60 N/mm2 concrete for severe condition with a mix design proportion. In this paper a complete structural analysis and design of offshore platform with wind turbine modelling and load calculations are done using IS codes. The analysis and design of these platforms are quite different from those of the conventional land-based structures. Modelling and complete structural analysis is carried out using structural software's CATIA and ANSYS.
