Abstract

A bistable valve 10 comprises a bistable disc 16 movable between a first position in which a first side 22 of the bistable disc 16 has a concave shape, and a second position in which the first side 22 of the bistable disc 16 has a convex shape. The bistable disc 16 includes a peripheral sealing region 32 on the first side 22 which cooperates with a static part 18 when the bistable disc 16 is in the first position to create a seal between the bistable disc 16 and the static part 18. A method for controlling the submergence of a foundation structure including a buoyancy tank comprising first and second bistable valves is also described.
