Case study of a defect detected and corrective action taken. Case study of online monitoring of three container cranes.
Using 3 x 32 channel and 3 x 16 channel systems to monitor each crane’s main hoist, boom lift and cross travel trolley.
Explain the use of the crane PLC systems that allows the MVX online units to collect and store data at the exact same machine operation condition to obtain accurate trending and spectral data of analysis and reporting.
Detailed study of the process information is required to determine the operational parameters for data acquisition.
Explain the difficulties in digital communication protocols across different companies and cloud server system setup.
Explain the complete solution from the PLC triggered inputs to the MVX units – Internet switches – cloud server – analysis – reports and customer server access.Case study of a defect detected and corrective action taken to potentially avoid a premature bearing failure.

-Complex monitoring of variable speed, variable load with reversible direction machines.
-Integration of PLC feed to the monitoring system to collect data at the same machine operating condition

Stephen started with condition monitoring at Olympic Dam Operations in South Australia. Progressed to Olympic Dam Operations Condition Monitoring Manager. Left Olympic Dam Operations and created my own condition monitoring company based in Adelaide called CMSA. Run and operated CMSA as a successful company with up to 35 employees until 2005 and sold CMSA to Schaeffler (FAG). Stayed on as manager to 2 1/2 years and then semi retired on a vineyard.
