摘要： A swivel-less coupling suitable for producing oil from an underwater well through a riser to a floating vessel or for transferring fluids to or from such a vessel is formed of an inner drum and a surrounding annular surface. The surface carries one or more flexible pipes which can wind and unwind helically across it to accommodate limited relative rotation as between the inner end(s) of the pipe(s) which is fixed to the drum and the outer end(s) and the pipe(s) which is fixed at a point which is rotatable relative to the drum. The pipe or pipes may be carried on cradles which can move across the surface. Relative movement as between the inner and outer ends of the pipe may be regulated by a motor, which may be controlled by sensors noting any tendency for change in the relative positions due to forces acting on the vessel.
