An offshore support structure is provided comprising at least one upper support structure section for supporting at least one functional device with a functional mass, at least one lower support structure section for founding the offshore support structure at a seabed of a sea and at least one transition support structure section which is arranged between the upper support structure section and the lower support structure section for physically connecting the upper support structures section and the lower support structure section. The upper support structure section, the functional device and the transition support structure section comprise together an upper support structure mass. The lower support structure section comprises a lower support structure mass. A mass ratio of the lower support structure mass to the upper support structure mass is selected from the range from 1.1 to 2. The lower support structure section forms a foundation of a offshore tower installation. The lower support structure section of is arranged at a seabed of a sea. Preferably, it is arranged such that the transition support structure section remains arranged above a sea water level (surface of water) of the sea. Thereby, tides which affect the sea water level have to be taken into account as well as a height of the highest waves. With such an arrangement it is possible that the transition support structure section is developed with a lower mass in comparison to an arrangement where the transition support structure section is in the water. Buoyancy force doesn't affect the gravity foundation function of the transition support structure section. The offshore tower installation is used for offshore wind power plants. |
