Abstract
When a flexible conduit is secured to a buoy under water, the action of the tide, current, wind and waves, as well as forces exerted by a vessel moored to the buoy, cause the buoy to perform various motions that bend or twist the tube and load it with additional tractive forces. This causes the tube to wear very quickly and to have to be replaced. The present invention solves this problem, by replacing that portion of the tube adjacent the buoy, by a pipe or rod which is fastened to the buoy with a universal joint and which hangs downwardly from the buoy in the water. At the lower end of the pipe or rod, a tube is connected which continues to the bottom of the body of water. The tube is coupled with the pipe or is directed through or along the rod, to the buoy.
