1. A method of installing an offshore wind turbine, the method comprising the step of:
raising a full-length tower for the offshore wind turbine by moving it longitudinally from a container in a floating substructure comprising a load-carrying device, the floating substructure being a support structure for the wind turbine; and
lifting equipment by the load-carrying device from a vessel to the floating substructure.
