How do such massive turbines float?

Floating offshore wind turbines float using buoyancy (the same way large ships float). They also are specifically designed to remain upright during storms, waves, and other events. Floating turbines are not floating freely in the ocean – rather, they are anchored to the seafloor so that they do not move around too much.
