A notable feature now found on some offshore wind turbines is a large sturdy helicopter-hoisting platform, or helideck, built on top of the nacelle, capable of supporting service personnel and their tools, winched down to the platform from a helicopter hovering above it.[2][3] Wind turbine rotors are stopped, feathered and locked before personnel are dropped down to or picked up from the platforms.[citation needed]
