The swivel/gooseneck should permit weathervaning of the shuttle tanker, but without rotating the vertical riser about the base.

  • The swivel should permit 360 degrees rotation in the horizontal plane.
  • However, rotation in the vertical plane should be provided by the yoke, to enable lowering and picking up of the catenary riser that leads to the off-loading shuttle tanker.
