What are offshore wind turbines and how are they different from onshore ones?
Offshore wind turbines, as the name suggests, are wind turbines constructed and located in bodies of water, such as the ocean or river estuaries. While the term is usually used to describe wind farms at sea, offshore wind farms can be located fairly close to shore.
There is no technical limit to the depth of water they can be built in; however, while it is theoretically possible to build in any depth, the maximum is probably closer to
1,970 feet (600m), practically speaking.

The methods used to construct them and anchor them will vary, however, for obvious reasons.
