ABSTRACT:
A passive tensioner is described for accommodating the tensile loading between a floating oil production platform and a riser. The tensioner includes a stack of strut elements, each of which has a plurality of struts of an elastomeric material individually configured to respond to a compressive load by buckling in a predetermined direction, means for constraining the stack during such buckling in a direction generally orthogonal to the direction of the compressive load and means for translating the tensile loading because of ocean wave, current or other liquid action on the platform into a compressive load and applying the same to the stack.
