Abstract
A riser system for use in transporting fluid cargo to a floating vessel from a submerged pipe employs a tensioning mechanism that prevents excess slack in a flexible riser that could potentially damage the riser. The tensioning mechanism includes a tensioning arm or element that is pivotally attached at a first end to a submerged base and at its second end to the flexible riser. The arm is free to rotate about the pivot point in a pendulum manner, but is urged toward an equilibrium position by one or more tension-applying elements disposed on the arm, such as a buoyancy element, a weight or both.
