WSC has had a plant-wide preventive maintenance system in place since 1994. The system is administered by Hartford Steam Boiler Reliability Technologies (HSBRT), an outside vendor. HSBRT facilitates the operation of the preventive maintenance system including completion of paperwork, initial set up, reporting, and providing an on- site manager. WSC personnel conduct the actual tasking and performance of preventive maintenance actions. Approximately 7,800 machine units are covered by the system.

Preventive maintenance actions are scheduled by issuing preventive maintenance work orders that specify the preventive maintenance task description, materials or tools needed, required skills, completion date, and special instructions. When preventive maintenance actions uncover equipment needing repair, a repair work order is filled out indicating the nature of the problem and specifying the work and materials required. Monthly preventive maintenance performance summaries are published for each department. Unfinished scheduled preventive maintenances are also tracked monthly including the reasons why a preventive maintenance task was not completed.

WSC has evaluated the scope of its preventive maintenance program to determine which preventive maintenance actions add value and which do not. The preventive maintenance system has been linked to other maintenance systems including predictive maintenance, oil analysis, and motor spares management.
