Abstract:

In recent years, various methods have been innovated and developed for attaining clean and renewable energies. In this regard different types of wind turbine at land and sea have been used for transforming kinetic energy to electrical energy. By considering cumulative power of wind at marine environment and also increasing cost of construction, implementation and operation in the environment, it is necessary to perform serious researches to optimize design costs. Among this, analysis of geometry parameters effects on applied forces on mooring and establishment of foundation in floating wind turbines and stability maintenance and optimization of mooring cost is very important. According to global statistics up to 2050, 12% of electricity generation in world will be obtained from renewable resources. The length of Iran shoreline is 5800 Km and the area of sea is 1900 Km2 that cause a good availability to high potential of renewable energy of wind [1]. A few studies had been performed by researchers on stability and establishment of offshore platforms and wind turbines. Among them Larsen analyzed spar platform and optimization its geometry [2]. Jain and Agarwal studied mooring behavior at spar platform affected by waves [3]. Raeis Zade and Motahar stated that use of turbine with horizontal axis is optimal on Persian Gulf [4]. Ketabdari and Mirzaee Sefat studied interactions of linear waveswith behavior of spar platform and modeled structural behavior against linear waves [5]. In present study, effect of geometry changes of different parts of wind turbines on applied forces and platform stability modeled and simulated by ANSYS AQUA Software and its effect on applied forces on mooring by considering JONSWAP wave spectrum areevaluated.
