摘 要：
A riser tensioner system for applying a substantially constant tensioning force to a riser and allowing a floating platform to move within a given range along a
longitudinal axis of the riser. The system includes a plurality of tensioner
assemblies each of which are coupled to the riser and to the platform. Each of the tensioner assemblies includes an upper member, a lower member, a connecting member coupled to the upper and lower members, and intermediate members coupled to the upper and lower members at a point intermediate the ends of the upper and lower members. At least one of the upper member, the lower member, and the intermediate members are
adapted to provide a constant tensioning force. The arrangement of the upper member, lower member, connecting member, and intermediate members
further provide a linkage whose centerline in angularly spaced from the longitudinal axis of the riser by a substantially
constant amount throughout the range of motion of the linkage.
