Confusion: Maintenance – should the focus be on inspection or repair?
Thread Content
Turnaround preventive repair (similar to minor repairs and adjustments)； There are also statements online: Planned maintenance. Current repair, minor repair, minor overhaul – these refer to regular repairs/maintenance, on-site repairs, and daily maintenance. Maintenance and upkeep are other terms used for such activities. Major overhaul, general overhaul, major repair – these denote large-scale repairs. T&I stands for T/A inspection, which is a turnaround inspection; OOS inspection refers to an out-of-service inspection. A major overhaul can be considered a T/A inspection, a Shutdown (S/D) inspection, or an OOS inspection – the difference lying in whether the repair is carried out during a planned shutdown or as a result of a malfunction. What are your thoughts on these various terms used to describe repairs? How to use it? :handshake
We don’t make such a fine distinction; it’s all called a shutdown, whether it’s an emergency shutdown that lasts a few hours or a planned shutdown that lasts 2 weeks. But there is a distinction between planned and unplanned. During maintenance, there should be a focus area – usually inspection is emphasized in normal operations, while repairs are given priority when the machine is stopped. There’s also PPM, Predictive Preventive Maintenance – preventive maintenance that can be carried out while the equipment is in operation.
It seems that the focus should be on inspection (routine inspections) during the testing phase.
