Abstract: A top-tensioned riser (TTR) is supported by a tensioning system on the deck of a floating platform. The tension ring may include an elastomeric layer which permits small angular and lateral displacements of the tension joint. The tension joint comprises a tapered section to resist the bending moment and shear imposed by the vessel's motion. The riser tension joint may be supported laterally by rollers below the tension ring. The rollers react on the tapered section when the riser strokes up and down. The tapered section may be engineered to maximize the use of the tension joint, and to reduce bending moment and shear loads imposed on the tensioning system. In certain embodiments, there may be a small gap between the rollers and the tapered section. In certain other embodiments, the rollers may be spring-loaded to increase the stability of surface equipment on the upper terminus of the riser.

Abstract: A weight system for divers employs both an interior and an exterior weight pocket. The interior weight pocket is secured at the interior distal end of the exterior weight pocket. The attachment point is a post at the interior end of the weight pocket. The weight pouch hangs from this post and is secured in the exterior weight pocket. The release force is more precisely controlled with a coil spring. More control of the opening force translates to reliability of operation and safety of the weight releasing mechanism. The weight pouch is also more precisely guided into and out of the exterior weight pocket and the lock mechanism is self-centering, allowing easy assembly or disassembly of the weight pouch into and out of the exterior weight pocket.
