BLM jacking systems use the rack-and-pinion principle and consist of a set of simultaneously operated units, allowing lifting and lowering of jackup-type platforms. The units can be used on square, triangular-lattice, or tubular legs. They are typically self contained and consist of a gearbox driven by an electric. .
Our GustoMSC patented Variable Speed Drive (VSD) version of the rack-and-pinion jacking system is designed for vessels with truss legs. Safe, smooth, and quick relocations depend. .
GustoMSC hydraulic jacking systems use positive engagement with double-acting hydraulic cylinders. The systems, based on the pin-in-the-hole. .
Rack-and-pinion skidding systems are used for moving the cantilever and the drill floor of a jackup rig to locate the well center at correct position. Our BLM skidding units are installed above the main deck and are based on the same proven technology used in. .
The continuous hydraulic jacking system consists of four individual yokes. Each yoke is equipped with a jacking pin and two double-acting hydraulic cylinders. The jacking speed is continuous. During normal jacking three out of four yokes are active and one is in.
