Shutdown Preparation Checklist

Although the terms are often used interchangeably, a shutdown generally refers to any planned stoppage of equipment or facilities for maintenance activities.

A turnaround is usually a larger and more complex event involving extensive maintenance, inspections, upgrades, and project work. Turnarounds often involve significant contractor involvement and can represent one of the largest expenditures in an asset’s operating lifecycle.

In practice, the distinction varies between organizations, but turnarounds are generally broader in scope and require more extensive planning and coordination.

Shutdown success is largely determined before execution begins.

Poor preparation often results in schedule delays, cost overruns, safety incidents, resource conflicts, and quality issues. In contrast, effective preparation enables organizations to execute work efficiently while minimizing operational disruption.

Preparation activities include scope development, scheduling, materials planning, contractor management, risk assessment, safety planning, and readiness reviews.

Many studies and industry experiences show that inadequate preparation is one of the leading causes of turnaround underperformance.

The planning timeline depends on the size and complexity of the event.

Minor shutdowns may require several months of preparation, while major turnarounds often begin 12 to 24 months before execution. Large facilities may even begin strategic planning several years in advance.

Early planning provides sufficient time to develop scope, secure resources, procure materials, conduct risk assessments, and establish schedules.

Organizations that delay planning frequently encounter avoidable execution challenges and increased costs.

Most shutdowns follow a structured lifecycle that includes:

• Strategic Planning
• Scope Development
• Detailed Planning
• Scheduling
• Procurement and Materials Preparation
• Readiness Reviews
• Execution
• Start-up and Commissioning
• Post-Shutdown Review

Each phase plays a critical role in achieving safety, schedule, cost, and quality objectives. A structured lifecycle approach improves control and reduces execution risks.

Scope development is the process of identifying, defining, and validating all work that will be performed during the shutdown.

This may include:

• Preventive maintenance
• Corrective maintenance
• Equipment inspections
• Regulatory compliance work
• Reliability improvements
• Capital projects

Clearly defined scope helps organizations estimate resources, develop schedules, manage costs, and control risks. Poor scope definition is a common contributor to shutdown performance issues.

Scope creep occurs when additional work is added after the approved shutdown scope has been established.

While some changes may be necessary, uncontrolled scope growth can significantly impact schedule performance, resource requirements, and budgets.

Organizations can control scope creep through:

• Formal change management
• Scope freeze milestones
• Approval processes
• Impact assessments
• Strong governance structures

Maintaining scope discipline is one of the most important factors influencing turnaround success.

Shutdown work should be prioritized based on risk, safety, regulatory requirements, production impact, and asset criticality.

Typical priority categories include:

• Safety-critical work
• Statutory inspections
• Reliability-critical repairs
• Production-impacting activities
• Improvement projects

A structured prioritization process ensures that limited resources are allocated effectively and that critical work is completed within the shutdown window.

Shutdown readiness refers to the organization’s preparedness to execute the shutdown safely and efficiently.

Readiness includes confirmation that:

• Scope is approved
• Schedules are finalized
• Materials are available
• Contractors are mobilized
• Procedures are prepared
• Risks are assessed
• Safety requirements are addressed

Readiness assessments help identify gaps before execution begins and reduce the likelihood of surprises during the event.

Readiness reviews are formal evaluations conducted at predetermined milestones before execution.

The objective is to verify that planning activities have progressed to an acceptable level and that all critical elements are in place.

Typical review areas include:

• Scope maturity
• Schedule status
• Materials readiness
• Resource availability
• Safety planning
• Risk management

Readiness reviews provide management confidence and support informed decision-making.

Materials readiness is one of the most critical success factors for shutdown performance.

Missing spare parts, delayed deliveries, or incomplete staging can create significant work delays and negatively affect schedule compliance.

 Effective materials planning includes:

• Early identification of requirements
• Procurement planning
• Inventory verification
• Material staging
• Contingency planning

Organizations that achieve high levels of materials readiness generally experience smoother execution and improved productivity.

Contractors often perform a substantial portion of shutdown work.

Effective contractor management includes:

• Early engagement
• Clear scope definition
• Competency verification
• Performance monitoring
• Safety orientation
• Communication planning

Contractor performance can significantly influence safety, quality, schedule, and cost outcomes during shutdown execution.

Maintenance teams provide technical expertise that supports scope development, work planning, labour estimation, and execution readiness

Their responsibilities often include:

• Equipment inspections
• Maintenance strategy reviews
• Job planning
• Resource estimation
• Quality assurance

Maintenance involvement is essential for ensuring shutdown objectives are achieved effectively.

Operations personnel are responsible for safely preparing equipment for maintenance activities and supporting restart activities after completion.

They contribute to:

• Equipment isolation
• Permit management
• Startup planning
• Operational risk assessments
• Coordination activities

Strong collaboration between maintenance and operations teams is critical for shutdown success.

Risk management helps organizations identify, assess, and control uncertainties that could affect shutdown performance.

Common shutdown risks include:

• Safety incidents
• Schedule delays
• Resource shortages
• Technical failures
• Scope changes

Structured risk management enables proactive decision-making and improves overall execution performance.

Common mistakes include:

• Late planning
• Poor scope definition
• Insufficient materials preparation
• Weak contractor management
• Inadequate risk assessment
• Lack of schedule discipline
• Ineffective communication

Most shutdown performance issues can be traced back to planning deficiencies rather than execution failures.

Safety performance improves when safety considerations are integrated into every stage of planning and execution.

Best practices include:

• Risk assessments
• Job safety analyses
• Permit-to-work systems
• Workforce training
• Safety observations
• Leadership engagement

Safety should be treated as a core planning requirement rather than an execution activity.

Common shutdown KPIs include:

• Schedule compliance
• Cost performance
• Safety performance
• Scope completion
• Productivity
• Materials readiness
• Quality performance
• Startup success

These indicators help organizations evaluate shutdown effectiveness and identify opportunities for improvement.

Typical causes include:

• Scope growth
• Schedule delays
• Contractor inefficiencies
• Materials shortages
• Rework
• Poor planning

Strong governance and preparation are essential for controlling shutdown costs.

Successful turnarounds typically demonstrate:

• Strong leadership
• Clear objectives
• Effective planning
• High materials readiness
• Strong contractor performance
• Excellent safety results
• Schedule compliance
• Controlled costs

Most importantly, successful turnarounds achieve their business objectives while preparing assets for reliable operation in the years ahead.
