Materials and Spares: Why Late Parts Can Extend a Shutdown

Turnaround schedules can be highly detailed.

But even the best schedule can fail if the required materials are not available when the job begins.

A missing gasket, incorrect valve trim or delayed exchanger component can hold up work that many other activities depend on.

Material readiness is therefore a critical part of turnaround preparation.

Identify Long-Lead Items Early

Some parts may require months to manufacture.

Examples can include:

  • specialised valves
  • compressor components
  • exchanger bundles
  • turbine parts
  • custom gaskets
  • proprietary internals

These items need to be identified well before shutdown execution.

Purchase Order Placement Is Not Enough

A part may appear “ordered” in the system while still creating risk.

Teams need visibility on:

  • manufacturing progress
  • inspection
  • shipping
  • customs
  • site delivery

Critical items may require active expediting rather than passive order tracking.

Incoming Inspection Matters

Receiving the part is not the same as having the correct part.

Before shutdown, plants should verify where appropriate:

  • dimensions
  • material
  • quantity
  • certification
  • compatibility
  • physical condition

Finding a mismatch before the shutdown provides time to correct it.

Finding it after equipment has been opened can extend downtime.

Materials Need to Reach the Workfront

Large turnarounds involve substantial quantities of parts and consumables.

Good logistics ensures that crews do not waste time searching warehouses or waiting for transport.

Kitting materials by job can improve execution efficiency.

Contingency Spares Can Protect Critical Work

Inspection may reveal damage that was not fully known before opening equipment.

For high-risk equipment, plants may hold contingency parts for likely findings.

This avoids having to begin urgent sourcing after the shutdown has already started.

Storage Conditions Matter

Some materials can deteriorate if stored incorrectly.

Seals, gaskets, electrical components and specialised materials may require controlled storage.

Turnaround readiness therefore includes verifying that stocked parts are still usable.

Material Readiness Protects the Schedule

A shutdown crew without the required part cannot complete the job, regardless of how well the activity was planned.

Strong turnaround preparation ensures that the right materials are available, verified and positioned before they are needed.
