Machine Health Check

Aspec Engineering - Machine Health Check

Control systems on Stackers, Reclaimers and Shiploaders have advanced greatly in recent years and large SCADA* datasets from onboard instrumentation exist.  The data can be utilised as part of asset management reviews to understand the structural loadings, fatigue cycles and productivity of the machines.  Over the last 5 years, ASPEC has invested in developing advanced algorithms that process raw data from the SCADA* system into engineering information.  This allows experienced engineers to perform a ‘Machine Health Check’ that includes the items listed below.

The machine health check validates if the machine is operating within its safe structural design envelope, and helps stakeholders visualise the performance of the machine. If it is done on a routine basis, the health check report can also be used to study the impact of changed operating conditions and for benchmarking across machine fleets.

ASPEC carries out annual health check of machines at several sites in Queensland, NSW and Western Australia as part of machine risk management audits.  ASPEC recommends machine owners should include the Machine Health Check in engineering audits at least every 4 years.
