MRO of rotating equipment


Rotating equipment is a general classification of machinery and equipment designed to generate reciprocating or circular motion, which is then used to move or agitate materials. Rotating equipment works through a system of drivers (machinery that uses an external energy source like fuel or electricity to provide the source of power to do work, for example turbines, engines or motors), driven components (equipment that uses the power source to do specific work, for example generators, pumps or compressors), transmission devices (equipment or components involved in the transfer of motion or energy from one machinery/equipment to the next, for example gears, clutches and couplings), and ancillary equipment and systems (for example inlet air system and filter, fuel system, exhaust duct and piping system).

Rotating equipment is used in many different industries, including O&G (upstream and downstream), power generation, mining, agriculture, manufacturing, transportation and construction. Rotating equipment is also used in commercial applications, including for heating, ventilation and air-conditioning, escalators, elevators and travellators and back-up power generators.

We are a MRO specialist for various types of rotating equipment, including gas and steam turbines, engines, motors, generators, pumps, compressors and industrial fans. Our MRO services are currently focused on rotating equipment used in the energy industry, including O&G production and refineries and power plants. These include rotating equipment at the following locations or applications:

  • power generation;
  • petrochemicals;
  • crude O&G refineries;
  • process and export gas compression;
  • crude oil handling or main oil line;
  • natural gas, liquids and chemical injection; and
  • fire water pump
Types of MRO Services Offered


Predictive Maintenance

  • Uses the actual condition of the rotating equipment to determine the timeliness and type of maintenance services that need to be carried out
  • Offer various inspection techniques which include, among others, oil analysis, vibration analysis, leak detection, and visual aid inspection
  • Rotating equipment such as gas and steam turbines, process pumps, gas compressors
Equipment Overhaul

  • Requires the entire equipment to be stripped down to its parts and components for cleaning, repair, reconditioning, replacement and recalibration
  • Include, among others, machining, fabrication, balancing, alignment, buffing, blasting and coating

Balancing and Alignment

  • Rotor balancing and alignment of rotating shafts
  • Utilise balancing machines to identify the position and amount of imbalance and perform rotor balancing by removing or adding weight to the unit so that the mass is distributed evenly around the true axis
  • Alignment of rotating shafts using several methods such as conventional methods using dial indicators and more complex methods using laser alignment

Replacement and Upgrades of Components and Parts

  • Inspect, analyses and recommends components and parts, which require replacement, including among others, turbine disks, rotating and stator blades, turbine buckets, alignment hardware and balance weights
  • We complement our in-house machining function with external computer numerical control part manufacturers who operate computer numerical control machines with higher functionality, precision and specifications

Maintenance of Process Control and Instrumentation

  • Process control systems are commonly used to execute and control one or more processes in an industrial application
  • Instrumentation is the application and usage of devices that either detect or measure operating or environmental variables
  • Includes process control such as SCADA(1), PLC(2), RTUs(3), and instrumentations such as flow meters, level measuring instruments, gas analysers, pressure gauge, actuators as well as final control elements such as control valves, dosing or injection pumps
