Evidence-based maintenance

Instead of using the calendar as a " plan " , it is based on criticality, running loads and real measurements, focusing on areas that affect safety, usability and longevity.

Maintenance how to proceed (example)
1

Asset baseline

Establishment of a baseline for equipment structure and configuration, solidification of asset identification and key parameters.

Baseline time2023-05-18Scale Capacity5.02 MWh
2

Risk / Use to plan

The maintenance cycle is determined dynamically based on criticality, frequency of operation and use of the scene.

Risk levelHighNext maintenance window45 days
3

Preparation for work

Preparation personnel, tools, spare parts, programmes and operating permits.
