A planned or unplanned cessation of operations to safely stop a process, asset or facility.
A Shutdown is the controlled cessation of operations for a process, equipment item or facility to allow maintenance, inspection, repair, modification or to respond to abnormal operating conditions. Shutdowns may be planned or unplanned and are executed using defined operational procedures to ensure personnel safety, equipment protection and environmental compliance.
Shutdowns safely cease operations to support maintenance, inspection, repairs or emergency response activities.
Planned shutdowns are typically coordinated with maintenance and inspection activities, whereas unplanned shutdowns occur in response to equipment failures, process upsets or emergency conditions.
A Shutdown is the operational event during which production is safely stopped, whereas Shutdown Management coordinates the planning and execution of that event.
