Shutdown maintenance is a planned period where equipment or an entire facility is taken offline to perform major overhauls, inspections, and modifications that cannot be completed during normal operations.

Shutdown maintenance, also called turnaround maintenance, is a planned period during which equipment, a production line, or an entire facility is taken out of service to perform major maintenance, overhauls, inspections, and modifications that cannot be carried out while the asset is operating. Shutdowns are common in process industries such as oil and gas, mining, power generation, and manufacturing where continuous operation makes it impossible to access certain components during normal running. Planning for a shutdown typically begins months in advance and includes scope definition, resource allocation, material procurement, contractor coordination, safety planning, and a detailed task schedule designed to minimise the duration of lost production. The scope of a shutdown can range from a single production line being offline for a day to an entire refinery or processing plant being shut down for several weeks, with hundreds of contractors working simultaneously on thousands of individual tasks that must be carefully sequenced and coordinated.

Why it matters

Poorly planned shutdowns are a major source of cost overruns, extended downtime, and safety incidents. Every additional day of unplanned downtime during a shutdown can cost an operation tens of thousands of dollars in lost production. Effective shutdown planning ensures that all required parts, labour, and permits are in place before the shutdown begins, that tasks are sequenced to minimise total duration, and that safety risks associated with simultaneous maintenance activities are controlled.

How MapTrack helps

MapTrack helps teams plan and track shutdown maintenance by centralising the work order backlog, linking tasks to assets, scheduling resources, and providing real-time progress dashboards so supervisors can identify and resolve delays before they extend the outage.

Frequently asked questions

How far in advance should a shutdown be planned?

Major shutdowns are typically planned six to twelve months in advance, with detailed scheduling beginning three to four months out. Planning includes defining the scope of work, ordering long-lead-time parts, arranging contractor resources, completing risk assessments, and obtaining any required regulatory permits. Shorter, routine shutdowns may require only a few weeks of planning depending on complexity.

What is the difference between shutdown maintenance and outage maintenance?

The terms are often used interchangeably. In some industries, "shutdown" refers to a planned maintenance event, while "outage" may refer to either planned or unplanned periods when equipment is not available. In power generation, "outage" is the more common term. Regardless of terminology, the key distinction is whether the downtime was planned (with a defined scope, schedule, and resources) or unplanned (reactive, often with higher cost and risk).

How can organisations reduce shutdown duration?

Key strategies include thorough pre-shutdown planning to eliminate scope creep, pre-staging all required parts and materials, scheduling tasks in parallel where safe to do so, using condition monitoring data to refine the scope to only what is genuinely needed, conducting pre-shutdown toolbox talks and safety briefings, and tracking progress in real time so delays are identified and resolved immediately rather than discovered at the end of the outage.
