Preventive maintenance process
Ensuring a high availability of objects in the long term is an important part of Plant Maintenance. Preventive maintenance is used to improve the availability of the technical objects, without which repair costs will be higher.
The scope of planned maintenance includes Preventive Maintenance, TBM on any type of Plant / Machinery.
One of the most significant advantages offered by the SAP Plant Maintenance application component is the option of split-level maintenance. You can use maintenance planning to describe the dates and scope of preventive maintenance and inspection activities of technical objects. You can plan for your technical objects to be maintained on time and thereby function optimally.
Maintenance Plan
Description of the maintenance and inspection tasks to be performed at maintenance objects. The maintenance plans describe the dates and scope of the tasks.
Preventive maintenance plan:
Maintenance is performed in specific cycles for time-based maintenance (TBM) planning, for example, every two months or every six months.
Periodic Inspection plan:
Inspection is performed in specific cycles for time-based inspection planning.
Counter based Maintenance:
With counter based maintenance plans, you can plan regular maintenance based on counter readings maintained for measuring points at pieces of equipment and functional locations.
Maintenance takes place when the counter for the technical object has reached a certain reading, for example, every 100 operating hours, every 500 operating hours etc. The calculated planned date depends on the counter reading at the time of planning, and the estimated annual performance that has been defined for the counter.
You can use performance-based maintenance planning to ensure that the operations contained in the maintenance task list are performed at a time when the technical object actually requires maintenance.
Maintenance order:
Orders form an important part of the detailed planning of tasks and their accompanying documentation in Plant Maintenance.
A technician on site must execute tasks on a technical object. For this, materials, tools and staff must be planned and costs estimated. The order supports you with these tasks, since it primarily contains data for planning and executing tasks, which must be performed at the technical object in question.
Maintenance scheduling:
We schedule a maintenance plan with which the system generates maintenance orders for the defined cycles.
For each scheduling, the system calculates the due date (planned date) for a maintenance call object based on the scheduling parameters and the defined frequency like weekly, monthly, quarterly, yearly etc and generates maintenance calls.
Maintenance Order Confirmation:
A completion confirmation documents the status of the processing of operations and sub-operations for a maintenance order. It is a part of order monitoring.
Maintenance order confirmation listing gives details like which work centre performed the work, how long the work was done, how much work is still pending and clearing the reserved resources.
Purpose
• To carry out preventive maintenance on the technical object based on fixed frequency.
• To meet some legal requirement (Statutory) like reminders through calls for submission of ‘return statements’.
• For planning of procurement of components and provision of service for any technical object in fixed interval.
• Budgeting of resources like men and material.
• To plan for checking the health condition of the machine and optimize on the maintenance schedules based on the result.
• For execution of checking the condition of same equipment following more than one time interval like monthly, quarterly.
• Mass planning of the preventive maintenance for whole lot of equipment.
• Plan for preventive maintenance collectively for a group of similar equipment.
• Any maintenance activity, which needs to be carried out at certain frequency, can be planned and scheduled using this functionality’ can be specified here.
