Abstract
A cantilevered jack-up rig having a support for supporting the free ends of the rig's cantilever beams when said beams are extended over a platform to be serviced by the rig, thereby maximizing the lateral reach of the rig and increasing the load capacity at the maximized reach. The support is positioned between the top of the platform and the bottoms of the extended cantilever beams. The top of the support is provided with a motion block to facilitate lateral and rotational motion of the extended cantilever beams relative to the support.
