A device for installation on a seabed (S) below a body of water (W) comprises a first wall element (23; 5; 7a-c) having a second wall element (22; 2; 4a-c) extending from and along the periphery of the first wall element, the first and second wall elements thereby defining an open compartment (20; 9; 3a-c). The second wall element is adapted for penetration into the seabed (S) whereby the compartment is closed by said wall elements and the seabed. A sealing means (F) is provided in the compartment (20; 9; 3a-c) and extending to the second wall element (22; 2; 4a-c), thereby defining a membrane (F) between the compartment and the seabed. The sealing means (F) comprises a membrane which is impervious to water. A foundation base (1) comprise a plurality of devices, connected via a central structure (5; 13, 13'). It is also provided an autonomous fluid control device (11) for controlling the flow of a first fluid and a second fluid, comprising a chamber (14) having a first opening (15) and a second opening (16). A closure element (17) is movable within the chamber (14) and adapted for selectively closing and opening the first opening (15) and the second opening (16), and comprising a material having a bulk density which is greater than the density of first fluid and less than the density of the second fluid. The closure element (17) may comprise a spherical element. |
