Description:
A calculation on manteinance requirements on reclaimers and stacker-reclaimer machines in australian Dalrimple Bay Coal Terminal. Idle capacity was used as proxy for manteinance requirements. A 10% threshold for an 8h moving average was established and used to dictate whether the machine required manteinance or not.
Objectives:
- Efficiency in Maintenance Scheduling: Utilize idle capacity data to strategically plan maintenance activities.
- Decision-Making Threshold: Implement a 10% threshold in an 8-hour moving average to accurately determine maintenance requirements.
- Operational Optimization: Aim to reduce downtime and extend machinery lifespan through data-driven maintenance decisions.
Detail:
The Dalrimple Bay Coal Terminal is located in Australia east coast, near the Bowen Basin, one of the largest coal mines in the world. After mining, the coal is transported by train to the DBCT, near Mackay, where it’s exported via the coal terminal and finally a cargo bay.
Machines
The machines that process the coal along the terminal are stackers, reclaimers and stacker-reclaimers. For the purpose of the assignment, only reclaimers and stacker-reclaimers data was used in order to assess the need for manteinance of every reclaimer-operating machine at the terminal (RL1, RL2, SR1, SR4A and SR6).
