TLP marine riser tensioner
A riser tensioner for use in maintaining a tension on a marine riser from a tension leg platform, the tension leg platform moving relative to the marine riser and the marine riser having a center line is described comprising: (a) an elastomeric assembly, adjustably deformable in pad shear, for maintaining the riser in tension during vertical movement of the platform relative to the riser, the elastomeric assembly having upper and lower ends; (b) a gimbal assembly for pivotally connecting the upper end of the elastomeric assembly to the tension leg platform to accommodate misalignment between the riser and the tension leg platform; (c) a base ring to which the lower end of the elastomeric assembly is secured; and (d) a collar, securely mounted on the riser, for resting within the base ring to connect the lower end of the elastomeric assembly to the riser.
