A method for offshore overboarding a structure on a vessel for subsequent lowering the structure to the sea floor, is using a crane (13) to lift the structure at its storage place on a deck of the vessel and move it by means of the crane to a position free of the vessel before lowering it into the sea. During at least a part of the overboarding movement of the structure (1), the structure (1) is forced to follow a track (2) along the deck of the vessel. Two apparatus for performing the method are also presented.
