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.

Drilling derricks and Rig Masts consist of a steel framework with a square or rectangular cross-section. Their purpose is to support the hoisting equipment and rack the tubulars while tripping pipe. The number of joints in a stand (single-double-triple) that the rig can pull is dependent on the height of the derrick. .
The Drawworks is one of the most important components of the drilling rig (types of drilling rigs). The unit supplies the hoisting power, the. .
The Crown Blockas a drilling rig component is a fixed set of pulleys (called sheaves) located at the top of the derrick or mast, where the drilling line is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks in this fashion,. .
The Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. .
Attached to the bottom of the traveling blocks, the hook is required to hang the swivel and rig kelly(for drilling) and the elevator bales (for tripping pipe and casing). .
