Abstract
A watertight compartment at a floating production plant handing crude oil and/or gas has at least one remotely releasable two-part connecting piece for a riser conduit between the sea floor and the plant. The compartment includes a sealing collar mounted in the bottom plating of the plant. The collar provides a sealing with respect to an upper half of the connection piece in relation to the compartment, as well as with a lower half of the connection piece, which is surrounded by water.
