A marine fluid transfer buoy is anchored to the sea bed employing two vertically displaced cardan joints. Connection between an undersea pipe and the fluid transfer buoy is made coaxial with the lower cardan joint and connection to a riser pipe to the surface is made coaxial to the upper cardan joint. All twist in the conduit at the connections is accommodated within a pressure container intersected by the two cardan axes which provides a protected dry environment for the conduit within.
