MONO PILE FOUNDATION

The invention relates to a monopile foundation (2) for an offshore structure, particularly for a wind turbine (W), having a foundation pile (3, 41, 74) for carrying the structure and a foundation reinforcement (4, 22, 44, 61) adjoining the foundation pile (3, 41, 74) on the outside, wherein: the foundation reinforcement (4, 22, 44, 61) has a sleeve (4, 45, 63, 75), a collar (9, 64, 76) and at least one support (8); the sleeve (4, 45, 63, 75) is assigned to the foundation pile (3, 41, 74) and the collar (9, 64, 76) is held at a distance away from the sleeve (4, 45, 63, 75) outwardly by the at least one support (8); the foundation pile (3, 41, 74) has a foundation section (GA) for inserting into the seabed (M) and a reinforcing section (VA) for connecting the foundation pile (3, 41, 74) to the sleeve (4, 45, 63, 75) above the seabed (M); and the collar (9, 64, 76) is designed for at least partial insertion into the seabed (M). According to the invention, so as to be able to achieve a satisfactory foundation for foundation piles of this kind, the foundation reinforcement (4, 22, 44, 61) comprises a plurality of, particularly two, three or four, reinforcing elements (11, 12, 20, 21, 47, 48) to be arranged adjacently to one another around the circumference of the foundation pile (3, 41, 74) and each of the sides of the reinforcing elements (11, 12, 20, 21, 47, 48) adjacent to one another in the circumferential direction are designed for interlocking, articulated and/or frictional connection to one another.
