Overview
Overview of TSC Rack and Pinion Jacking Systems
TSC designs, manufactures and sells advanced high-capacity jacking systems, including jacking units and Jacking control
systems, for various Liftboat and Jack-up rigs with the jacking capacity ranging from 180kips to 1,000kips.
■ TSC jacking systems offer safety, easy maintenance and a variety of outstanding features from the operation point of view.
■ TSC jacking systems range from SJ220, SJ350H, SJ450, SJ750 and SJ1000 suitable for harsh-environment liftboat or jack-
up rigs with water depth to 500ft. TSC jacking systems can be configured to suit any other Liftboat and jack-up rig design
requirement and specific customer needs.
■ TSC jacking systems can be delivered with product certificates from recognized Classification Societies such as ABS, DNV, CCS.
Operational Features
TSC rack and pinion jacking systems offer the following operational characteristics.
■ Variable speed control is realized by jacking control ■ Leg position indication and rack phase difference(RPD)
system(only VFD control system); detecting system (optional);
■ Classification Society approved offshore type electric motors ■ Two control modes: remote integrated control and local
and fail-safe disc brakes with realtime on/off/wear indication control;
are applied; ■ Remote access of the control system via secured internet
■ Easy automatic re-torque through PTMS and electric connection (optional);
control system;

Jacking Units
TSC Jacking Units
The TSC jacking system includes jacking units and the jacking control system. Each jacking unit is a compound gearbox, which
consists of an electric motor with a fail-safe disc brake, a parallel shaft gear reducer, a combined planetary Gearbox, a climbing
pinion assembly and a pinion torque monitoring system. TSC jacking units are available for the floating and fixed type jacking
structures, depending on the overall jack-up design.

Jacking Control Systems
TSC Jacking Control Systems
TSC supplies high reliability jacking control systems including two types: VFD control system and DOL control system. VFD
control system is composed of Variable Frequency Drivers (VFD), Motor Control Centers (MCC), Leg Length Detecting System,
Central Control Console (CCC), Local Control Consoles (LCC) and platform inclinometer. DOL control system is the direct-on-
line control system, suit for jacking systems equipped with NEMA D motor.
Main Functions
■ Variable Speed Control (VFD Design) ■ High Precision Inclinometer : Range: Biaxial ±30 °;
The jacking motors of each leg are driven by variable Resolution: ±0.001°; Accuracy: <±0.01 °

The Re-Torque Control can equally distribute the load PTMS are designed to measure the specific torque applied
among the jacking units of one leg. It is unnecessary for on each pinion and communicate to the jacking control

on the jacking units and re-torque can be performed
■ Leg Length Indication automatically.

be displayed on the CCC. In local control mode, the LCC can be used for load
transfer from rack chocks to pinions, and LCC may also fit
■ RPD Detecting System (Optional) for commissioning or repair work.
The “Rack Phase Difference” detecting system will detect
RPD by monitoring the position of each chord on a leg. The
RPD data is displayed on the Central Control Center and
enable the alarm before damage occurs.
