Rack And Pinion Jacking System

However one of the well known methods of elevating the jack up hull is rack and pinion.

Rack and pinion jacking system.

The rack jack from wmh herion provides simple synchronous lifting motion. This includes the complete package the heavy steel structures gear trains electric motors and controls. The system of rack pinion transforms linear motion to the rotation vice versa. Our blm skidding units are installed above the main deck and are based on the same proven technology used in our jackup elevating systems.

Tsc can offer jacking system used for the most jack up s in the world. Different from the conventional electrical rack and pinion jacking system where the jacking motors are typical direct on line dol abb utilizes advanced variable frequency drives vfd and vfd motors to optimise power consumption under different working conditions and improve operating flexibility and system reliability. 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. Providing quality unique gearboxes and solutions for use on industrial machinery.

This system uses multiple hydraulic or electric motors and gearboxes to distribute the torque between all legs to lift the whole platform smoothly and simultaneously. Designed and built in compliance with abs dnv rules for self elevating platforms vessels. Electric rack pinion jacking system hydraulic rack pinion jacking system cylinder jacking system. The rack and pinion jacking system is designed manufactured and tested in our plant in nantes france.

Offshore jack up rigs are the widely used in the world s oil gas exploration of which the key parts are legs and jacking systems. The gustomsc rack pinion system offers jacking speed up to 0 8 m min and leg handling speed up to 1 2 m min therefore the jacking operation is no longer the decisive factor during a rig move. Patented load sharing devices ensure equal load distribution over the pinions increasing safety and lifetime of the jacking system. Variable speed rack pinion jacking system description the gustomsc jacking system offers safety minimum mainte nance and a variety of outstanding features from an operational point of view.

Hydraulic rack and pinion systems in the range of 500 to 2 000 tons per leg contain in house fabricated motors power units and control systems using standard or tailor made components. There is a multiple jacking system on the jack up rigs used. Capable of lifting a load upwards of 93 600 kips. Re torqueing can be performed automatically by the vsd control.

Cost effective and reliable system for over 100 vessels worldwide.
