Abstract:
1. A method of installing an offshore wind turbine comprising the steps of: securing at least a part of a wind turbine to a transport vessel at a loading site by bringing at least one set of jack-up means located on the transport vessel into contact with the part and raising the part in a parallel direction relative to the longitudinal direction of the wind turbine by jacking up the wind turbine relative to the vessel; moving the transport vessel from the loading site out to an installation site; securing the transport vessel to at least a part of an offshore foundation which is located at the installation site, wherein the offshore foundation is configured to receive and hold the wind turbine; and lowering the wind turbine onto an upper part of the offshore foundation by jacking down the wind turbine relative to the vessel using the at least one set of jack-up means, wherein the transport vessel is secured to the offshore foundation by moving at least one holding means out of a hull of the transport vessel and into contact with the offshore foundation.
