摘要： The invention relates to a seabed foundation (1) for an offshore facility, comprising a primary pressure chamber (7) connected to a primary pump (8) and one or more secondary pressure chambers (9) connected to one or more secondary pumps (10). According to an embodiment of the invention, said primary pump is a suction pump and said secondary pump is a pressure pump. The invention further relates to a method (12) of installing said foundation on the seabed (19), which comprises the steps of activating (14) said primary pump to create negative pressure in the primary pressure chamber (7), so that the foundation sinks into the seabed, and activating (15) said one or more secondary pumps (10) to create positive pressures in the secondary pressure chambers (9), so as to control the alignment of the foundation with respect to a substantially horizontal axis (16) during the sinking into the seabed.

摘要： Method for assembling an offshore wind turbine (1), wherein the wind turbine (1) comprises a tower foundation (2) with at least one hollow ballast chamber (24, 25), wherein the method comprises the following steps:
- assembling the tower foundation (2) on a dry dock-like construction site (6), wherein the construction site (6) is located below the sea level (8) and separated from the sea (7) by a barrier (9),
- launching the tower foundation (2) to the sea (7) by, at least partially, removing or opening the barrier (9) and/or filling water into the construction site (6) leading to a flooding of the construction site (6),
- towing the swimming tower foundation (2) to a target position (26) on the sea (7) by a vessel (27),
- loading the at least one ballast chamber (24, 25) of the tower foundation (2) with ballast material (24, 25) causing the tower foundation (2) to sink down until it permanently rests on the sea ground (31), and
- installing a tower (3) of the wind turbine (1) on the tower foundation (2).
