Ship and method for transporting and setting up offshore structures

摘要

The ship has a hull (2) with U-shaped cross-section comprised of an open stern (12). A projection (9.1) of a side wall (4.1) extends over a rear edge of a ship base, and lifting support systems (16.1, 16.2) are integrated in the hull and movable in a vertical direction with its lower ends into positions below the ship base. A crane (20) i.e. gantry crane, is movable on upper edges of the side wall. The side wall is recessed at a lower side in a region of the projection so that a lower edge of the projection is arranged above a water line of the hull during travel. An independent claim is also included for a method for transportation and erection of offshore-structures.
