<p>An improved hose structure is provided for passing fluid across a pivot joint, that permits a transfer structure to pivot about two horizontal axes with respect to a vessel or the like at the sea surface. A middle conduit has a lower end connected to a pipe on the transfer structure and an upper end connected to a pipe on the vessel. The middle conduit can pivot, either by being flexible to bend along its length, or by being rigid but with flexible joints at its opposite ends. The pipe on the vessel can move up and down and is biased upwardly. When the transfer structure tilts, to raise or lower the lower end of the hose, the upper end can also rise or fall.</p> |
