Shut down management For Coal handling plant of thermal power station –A New Approach By Makarand Joshi 1.0 Abstract : - Shut down can be defined as scheduled down period for a plant for scheduled maintenance for an extended period of time. Shutdowns provide unique opportunities to a maintenance department not normally available during standard operation or even during short shutdown periods. A large work is required to schedule into a relatively short period of time. The process of project management is generally applied to a maintenance shutdown in coal handling plant of thermal power stations. The critical path method (CPM) or sometimes a Gantt charts is used for planning shut down. But it is observed that existing method is not sufficient and foolproof for such type of work. This paper covers a new method (MUC), which is developed for shut down management of coal handling plant of thermal power stations. 2.0 Introduction: - In a coal handling plant of thermal power stations there are different streams for transporting of coal up to bunker. Generally shut down is planed for a stream. Major equipment overhauls are performed during shut downs to prevent future breakdowns. Work schedules may have to be modified. Special equipment may have to be rented. Contractors may have to be hired to fill additional labor requirements and special needs. An effective system for the shut down maintenance should meet the following objectives. • Manage and prioritize all the work initiated. • Able to achieve the schedules • Manage site/plant access for resources, vehicles, equipment, and tools. • Manage indirect hire, contractor, subcontractor, and service personnel at
