ABSTRACT
However, compared with onshore, offshore wind power technology is more difficult and faces more new challenges [11-12]. For the benefit of offshore wind power development and construction, we should explore the offshore wind power development mechanism actively, to formulate a suitable development and construction management
1 INTRODUCTION
As an important form of renewable energy, wind power has many features such as it has abundant reserves, is renewable, is widely distributed, has almost no pollution and so on, making it an important direction for renewable energy development [1]. The development pace of wind power in China is fast. The new wind turbine installed capacity in 2012 were 12960 MW, the cumulative installed capacity of wind turbines was 75324 MW, which were both ranked first in the world [2-3]. However with the rapid growth of China’s wind power installed capacity, onshore wind resources were less and less, leading to the wind turbine market growth rate falling sharply. In addition, due to the limitation of current large-scale wind power grid transmission capacity, the situation of abandoned wind is severe; consuming onshore wind power has become the biggest obstacle to wind power development. Compared to onshore wind, offshore wind is good quality, close to the traditional load centers, easy to be consumed by power grid, which eliminates the problems of long-distance transmission; so in the future wind farm construction will be transferred from land to the ocean [4-6].
