Hydranautics Hydraulic Systems, Goleta, Calif., announced recently the shipment of a cantilever and drill floor skidding system contracted by National Supply Company of Houston for use on a rig which has been committed for operation by Cliffs Drilling in the Texas Gulf. The equipment was specified by the rig designer, Donhaiser Marine, Inc., also of Houston.

The contract called for Hydranautics to supply a set of 50-short-ton Gripper Jack assemblies, a set of 150-short-ton Gripper Jack assemblies and a control console. According to Hydranautics, the load skidding equipment will allow a substantial cut in the amount of fabricated steel that would otherwise be required in the construction of the rig.
