Introduction
Problem solving has proven to be much more difficult than condition monitoring. There were severe cases where condition monitoring results solved problems, but recur within a few weeks. Typical scenarios occur when problems are not identified at its root cause. More that often, the bearings would be replaced again. The bearings would make noise again within a few months after replacement, not knowing that the bearing has deteriorate due to the unbalanced condition that existed within the fan impeller. What the ‘unbalanced fan’ requires is a dynamic balance correction that will fix the problem. Upon rectification, the bearing will have a longer operational life.
The following services we provide are based on the extensive experiences in various industried where decisions by clients to implement such program or otherwise could be a distinction between prosperous economic growth or unforeseeable catastrophic failure.

The evolution of maintenance technique and technology was driven by the necessity to improve asset reliability & operational costs. Expert analyst, coupled with the latest sophisticated technologies has reengineered maintenance philosophy to new heights, thus making assets more reliable to a point of immortality. The essence of successful maintenance optimization is usually owed to the works of experience diagnosticians to accurately ‘pin-point’ the type of fault in an asset in order to formulate the right ‘antidote’. The following literature briefly explains the methodology adopted by diagnostic specialists who ‘sift-out’ problems to its root cause to arrive at a cost effective cure for any machinery fault.
Condition Based Maintenance (CBM) is self explanatory, i.e. to maintain a piece of equipment based on the physical condition of an asset. In short – to maintain a Bad equipment, and defer maintenance for the Good equipment. CBM enables engineers to identify a fault more accurately, thus resulting in significant reduction on the running costs due to planned maintenance executed more efficiently and at a convenient time with all the right equipment for the job available.
Predictive maintenance will definitely lead to a reduction in spare part stock holding. This is possible because vibration diagnostics is able to identify undesirable symptoms down to component level, giving engineers the information edge to plan on which part requires replacement and those sacrificial components that requires necessary stocks.
RDB is usually emphasized for equipment that exhibits incipient faults, usually falling into the improvement to unsatisfactory category (ISO 10816). Our RBD services have spanned from vibratory abatement in micro-semiconductor machines to diagnosing perpetual structural cracks on buildings & marine hull. These challenges are achievable through coordinated analysis derived from the following techniques:
§ Vibration Profile Analysis
§ Phase Dynamics
§ Simultaneous Data Acquisition
§ Strain Gauge Instrumentation
§ Thermodynamic Profiling
§ Acoustic Abatement
§ Process Analysis
§ Dynamic Failure Assessment
§ Finite Element Analysis
§ Asset Maintenance & Management
