ABSTRACT:
A gripping assembly for moving drilling rigs on offshore drilling platforms in which the drilling rigs are supported on a plurality of skid bases. The gripper assembly rests on the skid bases and provides means for selectively gripping the skid base when a drilling rig is to be moved. The gripper assembly has a platform supported by end plates resting on the skid base flanges and is connected to the drilling rig by a hydraulic jack cylinder which moves or slides the drilling rig on the skid bases in a stepwise fashion. Traversing the platform is a cross-member pivotally supporting gripper arms for applying a clamping force to the skid base. The gripper assembly is clamped on the skid base by means of a clamping hydraulic cylinder to apply a force on flanges on the gripper arms, while the hydraulic jack cylinder is operated to push or pull the drilling rig a distance equal to the extension distance of the hydraulic jack cylinder stroke.
