MARINE STRUCTURE AND METHOD

The invention provides a marine structure, comprising: ajacket-structure for supporting a functional element in a body of water, the jacket-structure comprising at least one float element having a first buoyancy, and at least one linear guide sleeve; a sub- structure comprising a countenNeight structure having a second buoyancy and at least one leg extending through the at least one guide sleeve, the at least one leg having a lower end connected to the countenNeight structure and having an upper end provided with a stop element, wherein the at least one leg is movable through the corresponding guide sleeve between a towing position, wherein the stop element is remote from the guide sleeve and wherein the guide sleeve allows linear motion of the at least one leg with respect to the support structure, and an operating position, wherein the stop element engages a corresponding counter element of the guide sleeve and wherein the at least one leg is fixated with respect to the at least one guide sleeve.
