Creating a commissioning baseline for ceramic linings

Complete the specified cure and release checks before the equipment is loaded. Record cleanliness, finished lining map, joints, terminations, fasteners, repairs, dimensional results and every accepted deviation. Photograph the whole equipment in a fixed sequence, with close views tied to permanent coordinates. Clearly separate ‘not inspected’ from ‘inspected with no observed issue’. Close temporary openings and confirm that tools, debris and protection materials have been removed. The pre-service record should be signed or otherwise released through the project’s document process. Once material flows, dust and early marks can obscure whether a feature existed at handover.

A baseline fails when its files cannot be connected. Use one equipment identifier, consistent zone names and revision status across the as-built drawing, dimensional report, inspection map and image register. Link repaired locations to their material and installation records. Keep the source files rather than only a presentation assembled from compressed pictures. State the coordinate convention and viewing direction in the package. If the design changed during installation, archive the superseded drawing and clearly identify the final one. Maintenance should be able to open a mapped zone and find its initial photograph, dimensions and repair history without reconstructing the project filing system.

Record when process exposure begins and which startup steps place material, liquid, pressure, temperature or mechanical load on each zone. Link available feed description, flow or throughput indication, valve and pump state, temperature history, cleaning and any recirculation to that timeline. Note deviations such as blocked feed, unexpected oversize, prolonged low flow or rapid temperature change. These are observations, not automatic causes. If equipment configuration differs from the design or commissioning plan, capture the actual state. A baseline built only from pristine photographs cannot explain whether the first wear pattern developed during controlled operation or an atypical startup.

Set observation opportunities according to equipment risk, access, operating cycle and the mechanisms the design is intended to manage. A first-impact zone may need attention for fresh edge damage; a bonded overhead field for movement or detachment; a pipe transition for steps, leakage or changed pressure behaviour. Use safe external indicators where entry is not available and wait for approved isolation before internal inspection. Define what evidence is collected and what change triggers technical review. The timing should be early enough to detect a developing pattern but compatible with safe operation and meaningful process exposure. A calendar date alone is not a technical inspection plan.

Assign ownership for the baseline, storage location, revision and future updates. Operations contributes the first-load record; inspection adds mapped condition; maintenance records interventions; reliability compares change over time. Preserve the original commissioning snapshot and add dated layers rather than overwriting it. When an area is repaired, link the old condition to a new local baseline. When process or geometry changes, mark the comparison boundary so later trends are not treated as like-for-like. The handover is complete only when the teams who will inspect the lining can find, understand and use the package, not when the commissioning team has merely uploaded files.
