ABSTRACT:
An apparatus for tensioning a riser that extends from a floating platform to a subsea wellhead has hydraulic cylinders. The hydraulic cylinders attach between the platform and the riser in a cluster with the axis of the riser substantially parallel with the axes of the hydraulic cylinders. A guide sleeve within the cluster transfers bending moments of the riser to the platform.
