Abstract: The invention provides a method for the transport of a civil engineering structure in an aquatic medium. According to this method: at least one float is associated with the civil engineering structure in such a way as to ensure that the said civil engineering structure floats stably in an aquatic medium, the said float surrounding the civil engineering structure and a bottom portion of the civil engineering structure extending below the said float, and the civil engineering structure and the associated float are caused to move in the aquatic medium to a desired position.

Abstract: A contribution is made to the assembly of a wind turbine intended to comprise, in a final assembly condition, a tower (2) surmounted by a nacelle (4) cooperating with a rotor (5) receiving a plurality of blades (3a-3c). To this end, a temporary association is made between at least some blades from said plurality of blades and the tower, so that said blades extend substantially in the longitudinal direction of the tower.

Abstract: A fluid-cushion supporting arrangement for horizontal conveyance comprises a supporting platform having a center and a distal portion; a flexible angular sealing element arranged under the platform in the region of the distal portion and forming a sealing piston. The sealing piston has a substantially horizontal leg which extends toward the center and forms together with the supporting platform a fluid chamber, and a substantially vertical leg which forms together with the supporting platform a control pressure chamber. The vertical leg is vertically and adjustably inserted in the control pressure chamber. An inlet valve is provided for supplying fluid into the fluid chamber. A pressure-regulating arrangement in fluid communication with the fluid chamber and the control pressure chamber regulates the fluid pressure. The vertical leg comprises a plurality of reinforcement elements including at least one metallic strip.
