ABSTRACT:
A resilient unit able to accomodate a large movement comprises a stack of elastomeric bearing units arranged to be loaded in series and to deform primarily in shear. Preferably a plurality of the stacks are provided in a nested configuration and interconnected in series to enable even greater movements to be accommodated.
The resilient unit is particularly suitable for use on an offshore platform to accommodate movement between the platform and a riser pipe while also maintaining a tension loading in the riser pipe.
