China's offshore wind resources more abundant. Learned, 5-25 meters water depth, 50 meters height offshore wind development potential of about 200 million kilowatts, 5 to 50 meters water depth, height of 70 meters offshore wind development potential of about 500 million kilowatts, intertidal zone and subtidal zone tideland resources, deep sea wind energy resources are more abundant. Although rich resources, offshore wind power construction overall progress is relatively slow. , according to data on the offshore wind power development plan (2014 ~ 2016) of 44 project, only two have been completed and put into operation, the rest of the projects were approved under construction, to build or to carry out the preparation stage. The construction progress has been slow and China's existing huge offshore wind project risk has important relation.
