According to the exhaustion of natural gas and oil, the demand of renewable energies such as solar-, wind-and water-powers and fuel cell is increasing all over the world.The most important requirement of renewable energies is the efficiency and capacity, and in this regard wind power draws an intensive attention thanks to its potential to generate a huge amount of electricity from plenty of winds around us.Wind turbines in the early stage were designed for the installation on the ground and showed the rapid increase, to some extent, in both the total installation number and the maximum power generation capacity.However, this phenomenal worldwide trend encountered several obstacles such as the infringement of living environment and the limitation of being high-capacity and making large wind farm.This critical situation naturally turned the development direction of wind turbines to the offshore sites, a less restrictive installation place.
