A preventive periodic maintenance and inspection service plan is prepared in three separate tables: every 3 months, every 6 months, and every 1 year. These tables are presented to the investor. Within the framework of the prepared plan, periodic/preventive maintenance is carried out to extend the life of the system, equipment, or machinery, and to proactively address potential faults. The performed maintenance is reported to the investor, aiming to achieve maximum performance in production.
