Turnaround Inspections


Inspections are an integral part of all turnarounds and should be conducted for a number of reasons. The main reason is that, without high quality inspections, damaged equipment may continue to go unnoticed and eventually fail unexpectedly during regular operations. This not only could be detrimental due to the lost production during a potential shutdown, but it could cause a significant safety incident at the facility.

There are seven critical elements to the success of any turnaround inspection. These are:

  1. Safety

  2. Final planning

  3. Tracking

  4. Record keeping

  5. Having qualified personnel

  6. Cooperation and coordination between operators

  7. Having no weather related issues


One safety incident can quickly overshadow days of efficiency and productivity during a turnaround. Having experienced inspectors and supervisory personnel in the field is critical to maintaining a superior safety culture. An inspection team should feel comfortable stopping work when something looks unsafe. This comfort level only results from constant coaching and mentorship by the Sr. Level inspectors and supervisors.

Most of the planning should already be done before the turnaround begins, although these plans are likely to change as turnaround progresses. This is typically because corrosion or damage is often found during inspections, which usually require work, and thus modifications to the original plan. Among other things, final planning should include producing a list of all the areas and equipment that are tagged for inspection. The planned inspection activities to be performed should also be identified in detail, and a specific methodology should be assigned to each.

Tracking of turnaround inspection activities is often done with wall charts, on which every event, occurrence, and inspection is tracked. This way, inspectors know what has already been tested, the results of the tests, and what repairs need to be done. A record keeping system then needs to be developed in order to track the progress of the repairs as they are being done. At the very least, these systems need to be systematic, chronological, and consistently followed.

Inspection personnel should arrive to the site a few days before the turnaround to coordinate with the leads and safety personnel. Cooperation between these two parties is integral to the timely and efficient completion of the turnaround. While it doesn’t affect inspections, inclement weather can greatly slow down the progress of maintenance work.

Inspection work usually makes up about 60% of the workload of an average turnaround. Of the remaining 40%, about half of the workload (20%) involves implementing upgrades, while the other half (20%) consists of performing maintenance.
