Glass-Lined Equipment Inspection & Documentation Guide
Build a traceable record set around each inspection, repair and handover—so plant, maintenance and project teams can find the source, understand what remains open and pass the right information forward.
This guide covers inspection record organization and follow-through. Inspection methods, acceptance criteria and timing must come from the equipment supplier’s instructions and the qualified personnel responsible for the equipment.
A practical record workflow
Keep identity, source and action status visible from the first file received to the final handover. The sequence below is a document-control workflow, not an inspection procedure.
Identify the vessel
Match the equipment tag and available serial or nameplate details. Keep vessel, agitator drive and accessory identities distinct. See the nameplate data guide.
Collect source records
Gather the latest supplier, service and owner records. Retain original reports and note their dates, revisions and scope before summarizing.
Index observations
Record where a finding appears, which report describes it, and any supplied measurement or location map. Keep observations separate from diagnosis.
Close the handover loop
Assign follow-up to a named role, track the source of each close-out, and carry unresolved items forward with their status clearly marked.
Inspection file set: what to index
Use the supplier’s actual report set as the controlling record. Depending on the equipment and service scope, a file set may include the records below; not every project will use every item.
| Record type | Useful index details | How teams use it |
|---|---|---|
| Inspection checklist or service report | Equipment ID, inspection date, scope, provider, document number and revision | Shows what the report covers and provides the source for findings. |
| Glass-thickness report or map | Supplied values and units, measurement locations, method and technician/source when stated | Preserves location context for future review by qualified personnel. |
| Exterior or jacket inspection sheet | Areas covered, reported observations, reference photos and listed follow-up | Connects exterior findings to a specific report and equipment area. |
| Agitation-system and accessory checklists | Component identity, checklist date, noted condition and source record | Keeps drive, agitator and accessory records linked without merging their identities. |
| Plug, patch or repair chart | Repair location identifier, related work record, date and current status | Helps teams find repair history without treating a chart as a current-condition certificate. |
| Start-up and handover checklist | Checklist revision, completion date, open actions, owner and referenced attachments | Transfers project and operating information to the responsible team. |
The names and contents of supplier forms vary. Index the files actually issued for the specific vessel and service scope.
Make every finding traceable
A short, consistent register makes it easier to locate the original evidence and understand what action is still needed. Use the source report as the authority; the register is an index, not a replacement for it.
Identity & source
Equipment tag, visible serial or plate reference, report title, document number, issue date, revision and issuing party.
Scope & evidence
Areas covered, reported method where stated, observation text, supplied values and units, location map or photo reference.
Status & ownership
Action needed, responsible role, target date if assigned, close-out evidence, reviewer and unresolved or pending status.
Record-control checklist
Link reports to the vessel tag and keep component identifiers visible.
Store the issued report alongside any index or working summary.
Make superseded copies distinguishable from the current issued record.
Keep supplied maps, photos and location labels with the matching report.
Record the close-out source and leave open items visible until confirmed.
Use “pending,” “not supplied” or “not applicable” instead of assumptions.
Do not use the file index as an inspection verdict
A complete folder does not prove the equipment’s present condition, and an equipment plate does not certify a current inspection. Follow the supplier’s instructions and the site’s approved record process. Only qualified personnel should select or perform inspection methods and interpret technical results.
Frequently asked questions
Does a complete inspection file set confirm that a vessel is fit for service?
No. A file index helps locate evidence; it does not establish current condition or suitability. Use the applicable supplier requirements and qualified technical review for those decisions.
Can thickness readings from different reports be compared directly?
Keep the original values, units, locations, dates and stated methods together. A qualified reviewer should decide whether readings are comparable; this guide does not set a comparison method or limit.
How often should an inspection take place?
Use the equipment supplier’s current instructions and the site’s maintenance plan. This documentation guide does not prescribe an inspection interval.
