ABSTRACT:
To overcome problems with the pistons of an energy cell rotating and becoming misaligned with one another in response to the forces exerted on the energy cell by a riser tensioner system, a two-piece elastomeric spring is disposed about each piston to create an elastomeric strut. Each piece of the spring is composed of a plurality of elastomeric layers separated by relatively inelastic spacers. These springs facilitate the longitudinally flexing of the elastomeric strut while substantially preventing rotation and misalignment in the radial direction.
