A hydrostatic coupling device for rapidly releasing a first object immersed in water from another object resting on the sea bed. The device comprises a seal mounted in a groove in the first object, which in use will be pressed against the other object. The groove is formed as a closed loop delimiting a space at the surface of the first object facing the other object. The seal is formed as a membrane mounted along its sides and dividing the groove into an outer part, open to the ambient water, and an inner part, which via a pipe can be connected to a reservoir above the water surface. This reservoir maintains a liquid column pressure in the inner part, being a certain amount higher than the ambient water pressure. A pumping device removes water from the space delimited by the seal and both objects. |
