Abstract

A device for transferring fluid at sea between a fixed install-ation e.g. an offshore platform and a floating appliance e.g. a ship comprises a central tube connected at its lower end to a flexible tube itself connected to the fixed installation, and a bracing fixed to the tube. Receivers or floats are between the tube and the bracing. One at least of the receivers or floats has a constant vol. and a predetermined wt., while the other receivers are capable of taking a variable vol. by injection or escaping of a compressed fluid. The device incorporates means, pref. a differential pressure valve, for maintaining the compressed fluid at a pressure slightly above the external hydrostatic pressure during the rise of the device from the sea bed to the surface and means, pref. an adjust-able relief valve, for maintaining it at a pressure slightly below the external hydrostatic pressure during the descent of the device from the surface to the sea bed. The wt. of the receiver or float is prefixed so that when the pressure in the variable vol. receivers or floats is equal to atmospheric pressure, the device rests on the sea bed. The upper end of the tube includes a valve capable of being connected to the ship. The device can bring about the transfer of oil etc. at sea between a fixed installation and a ship easily and rapidly. It is of mod-erate cost and very reliable.
