A turnaround is a planned
event where production units are completely or partially removed from service
temporarily to allow for necessary updates, maintenance, or inspection.
Although numbers may vary depending on industry, a turnaround can be generally
categorized into unique phases, each consisting of key elements that must be
performed in sequence:
Phase
1: Planning
The planning phase of a
turnaround is the foundation of the entire activity. It’s in this phase that
the initial scoping, defining, and organization occur.
Phase
2: Preparation
The preparation phase
involves the development of plan details before a turnaround is implemented.
Preparation begins immediately after a turnaround plan is approved. Once
preparations are complete, you should ideally have a finalized work list and schedule,
and a cost estimate accurate to within 10 percent of the allocated budget.
Phase
3: Execution
During the Execution
phase, turnaround work should start immediately after equipment shutdown to
maximize the schedule. It’s impossible to predict every task that needs to be
done during the Execution phase, so you need to have accounted for such
unexpected events during the planning phase. This means having a process in
place that will permit you to stay on schedule and within budget.
Phase
4: Inspection
Once Execution work is
done, assets such as personnel, equipment, and other related resources must be
inspected for readiness for service.
Phase
5: Evaluation
An investigation schedule
must be implemented to evaluate the turnaround’s effectiveness, reconcile
costs, and close purchase and work orders.
