Abstract A submerged mooring system for a tanker which is being loaded, or unloaded. The mooring system permits the tanker to drift with the wind and/or current while maintaining the bow of the tanker headed toward the anchor point. The mooring system incorporates a swivel which rotates around a vertical axis as the heading of the tanker changes with variations in the wind and/or current. The swivel comprises a column means, a circular mooring ring loosely encircling and slidable circumferentially around the column means, means for retaining the mooring ring on the column means, and a slip ring linked with and slidable circumferentially of the mooring ring, the mooring line being connected to the slip ring. A hose for loading or unloading the tanker extends between the tanker and the mooring system and the mooring system incorporates another swivel which permits the hose to swivel about the same axis as the mooring swivel in response to changes in the heading of the tanker.
In a mooring system for a ship, or the like, the combination of: a column means; b. a circular mooring ring loosely encircling and slidable circumferentially around said column means through 360*; c. means for retaining said mooring ring on said column means; and d. a slip ring linked with and slidable circumferentially of said mooring ring through 360*, the diameter of said slip ring being small compared to that of said mooring ring.
