摘要：In an arrangement including remotely releasable couplings for riser conduits between the sea floor and a floating plant processing crude oil and/or gas, the couplings are located in at least one chamber below the water line of the plant. This chamber is closed towards the atmosphere and provided with at least one downwardly directed opening communicating with the surrounding water. Structure is provided for governing the air pressure in the chamber, which is accessible through an air lock.
