How to Digitally Document Reefer PTI Inspections with Structured Photo Documentation
Structured mobile capture, ISO 6346-validated container linking, spare part serial number tracking, and direct AEMS integration — replacing paper forms and WhatsApp threads with one audit-ready workflow.
Trusted by container depots, shipping lines, and leasing companies across Europe — from single-depot operators to large-scale terminal operators processing tens of thousands of photos monthly.
What Is Reefer PTI Photo Documentation?
Category Definition
Reefer PTI photo documentation is the process of capturing, storing, and distributing inspection photos during a reefer container pre-trip inspection — linked to a validated container number, timestamped at the moment of capture, and structured to support warranty claims, shipping line distribution, and compliance audit requirements. Effective digital PTI inspection documentation replaces paper-based forms, WhatsApp threads, email attachments, and shared folders with a single structured record per reefer unit.
ConPDS Implementation
ConPDS is the structured implementation of reefer PTI photo documentation for reefer technicians and depot operators. The ConPDS Checker mobile app captures inspection photos at the point of inspection, reads the container code via AI-powered OCR, and validates it against ISO 6346 standards (owner code, serial number, and check digit validation) — without manual entry. Replaced spare parts are photographed with serial numbers captured and linked directly to the reefer unit's container record, creating a traceable warranty and claim trail that can be distributed automatically to Maersk AEMS (Asset Equipment Management System) Container Maintenance & Repair APIs or any other shipping line or leasing company.
Who Needs Reefer PTI Photo Documentation?
Structured reefer PTI photo documentation is relevant wherever reefer units are inspected, repaired, or returned — and wherever warranty or shipping line evidence may be required after the fact.
Reefer workshops performing pre-trip inspections for shipping lines — where spare part serial number evidence determines whether warranty claims are accepted or disputed.
Container depots handling refrigerated units — where PTI records need to integrate with gate-in documentation and the broader depot inspection workflow.
Leasing companies auditing warranty claims — who require photo evidence of the specific replaced component linked to the specific reefer unit before approving reimbursement.
Shipping lines requiring AEMS-linked PTI records — where documentation must reach the asset owner's system immediately after inspection, without manual export.
Most reefer workshops still rely on paper PTI forms, photos sent via WhatsApp threads to an office inbox, and manual filing by container number. Each step introduces a specific failure risk — and PTI records are not typically challenged until weeks or months after the inspection.
Failure Patterns
Wrong container linked: Manual photo filing under an incorrect number makes warranty evidence unrecoverable when a claim is raised.
No serial number record: Replaced spare parts photographed but not linked to their serial number — warranty claims challenged or denied.
Timestamp lost in transfer: Photos sent via WhatsApp threads or email strip original capture metadata — evidence challenged in shipping line disputes.
Photos on personal device: When a technician leaves, inspection records leave with them — no central recovery path.
Operational Consequences
Warranty claims delayed or rejected — parts replaced correctly but evidence cannot be produced on demand.
PTI photo sets distributed manually — hours spent per week selecting, compressing, and emailing photo files.
Shipping line disputes unresolved — no verified record of when or where the inspection took place.
AEMS integration absent — photos captured on device but never connected to the shipping line's maintenance system.
A reefer workshop processing 30 units per day generates 150+ inspection photos daily across PTI checks, defect close-ups, and replaced component records. Without structured container-number linking at the point of capture, associating the right photo to the right unit — and the right serial number to the right warranty claim — becomes statistically unreliable at scale.
With manual methods: a technician photographs a replaced compressor, saves the image to their phone, and sends it via WhatsApp to the office. Three months later, the shipping line challenges the warranty claim — the photo exists but carries no verified container link, no serial number, and no verifiable timestamp. The claim is disputed and the depot absorbs the cost.
With structured reefer PTI photo documentation: the compressor is photographed in the ConPDS Checker app, the serial number is captured alongside the image, and both are linked automatically to the validated container number at the moment of capture. The complete PTI record — including the replaced part evidence — is distributed to the shipping line within minutes of the inspection closing.

STEP 01
Capture PTI Photos in the Workshop
The reefer technician opens the ConPDS Checker app and begins the inspection workflow. Photos of the unit exterior, visible defects, and all components under inspection are captured directly in the app — on the phones your technicians already carry, with no specialist hardware required. The app operates fully offline in workshops and port areas with poor connectivity, syncing automatically once network access is restored.
STEP 02
Validate the Container Number at Capture
The ConPDS Checker app uses onboard AI-powered OCR to read the container code from the unit at the point of capture. The number is verified against ISO 6346 standards — covering owner code, serial number, and check digit validation — and linked automatically to every photo taken during that inspection. No manual number entry, no transposition errors, no association failures. To understand how this validation process applies across all depot workflows, see the structured container inspection photo documentation software overview.
STEP 03
Document Replaced Parts and Serial Numbers
When a component is replaced, the part is photographed before and after replacement. The serial number is captured alongside the image and stored under the container record in the ConPDS dashboard. This creates a complete, traceable warranty and claim trail — specific to the reefer unit, specific to the replaced component — providing defensible supporting evidence in warranty and shipping line disputes.
STEP 04
Distribute to Shipping Lines and Store Centrally
Once the PTI is complete, ConPDS rule-based distribution dispatches the photo set automatically to the defined recipient — via email, FTP, SFTP, or directly to Maersk AEMS Container Maintenance & Repair APIs. The complete record is stored in the central ConPDS dashboard, searchable by container number, with every distribution event logged in the audit trail. Explore the reefer PTI photo documentation app to see the full integration and distribution capabilities.
Detailed Inspection Workflows Within Reefer PTI Photo Documentation
Reefer PTI documentation is not a single-photo event — it spans multiple distinct inspection stages, each with specific photo evidence requirements. ConPDS structures each stage within the same container record, creating a single chronological inspection history per unit.
Unit Identification & Exterior Condition
Pre-Inspection Baseline Documentation
The reefer unit's exterior is photographed as a standard set before inspection work begins — capturing overall condition, visible damage, and the unit identification markings. The container number is read by AI-powered OCR and linked to the record. This pre-inspection baseline is the foundation against which any post-PTI condition change is measured.
Defect Documentation
Specific Fault Location and Condition Evidence
Individual defects identified during the PTI are photographed in detail — showing location, nature, and extent of the fault. Photos can be captured alongside temperature calibration displays, controller panels, and unit model identification (e.g., Carrier or Thermo King units), creating a complete PTI evidence record that reflects the actual inspection sequence. Each defect photo is linked to the container record with a GPS-verified timestamp at the moment of capture, providing independently verifiable evidence of the unit condition at inspection.
Spare Part Replacement
Component-Level Warranty Evidence
Each replaced component — compressors, condensers, evaporators, valves, and related parts — is photographed individually before and after replacement. The serial number of the replaced part is captured and stored under the container record. This component-level documentation provides defensible supporting evidence in warranty and shipping line disputes — the specific evidence required when a shipping line or leasing company challenges a replacement cost.
Post-PTI Confirmation
Return-to-Service Condition Record
Once the PTI is complete and repairs are finished, the unit's post-repair condition is photographed and stored as the closing record for that inspection event. This confirms the unit has been returned to operational standard — providing the post-repair evidence required for shipping line authorisation and completing the inspection chain from pre-PTI condition through to return-to-service.

Reefer PTI photo documentation is the structured process of capturing and storing inspection photos during a reefer pre-trip inspection — linked to the container number, timestamped at capture, and made available for distribution to shipping lines, leasing companies, and asset owners. It replaces paper forms and WhatsApp threads with a single searchable record per reefer unit.
Does ConPDS replace our existing depot management system or M&R platform? ▼
No. ConPDS adds the structured photo evidence layer that DMS and M&R platforms cannot provide. It integrates with existing systems — including EOS, DepotMaster, and Maersk AEMS Container Maintenance & Repair APIs — without replacing or disrupting the workflows already in place.
Does ConPDS work offline in reefer workshops? ▼
Yes. The ConPDS Checker mobile app operates fully offline — the AI-powered OCR reads container codes and all core functions run without network connectivity. Photos and container records sync automatically to the central platform once the device reconnects.
Is reefer PTI documentation stored securely and is ConPDS GDPR compliant? ▼
Yes. Photos are encrypted on-device and during upload using 256-bit HTTPS encryption. Role-based access controls, configurable retention periods, and a complete audit log of all access and distribution events are included as standard. ConPDS is fully GDPR compliant throughout.
Can reefer PTI photos be pushed directly to Maersk AEMS? ▼
Yes. ConPDS integrates directly with Maersk AEMS Container Maintenance & Repair APIs, pushing PTI photos to the system immediately after capture — eliminating the manual export step and ensuring documentation reaches the asset owner without delay or manual intervention.
How are spare part serial numbers documented during a reefer PTI? ▼
Each replaced part is photographed individually, with the serial number captured and linked to the reefer unit's container record in the ConPDS dashboard. This creates a traceable warranty and claim trail that can be accessed instantly when a shipping line or leasing company challenges a repair or replacement cost.

What Happens Without Structured Reefer PTI Documentation
✗
Warranty claims rejected: Replaced parts photographed but not linked to a validated container number or serial number — evidence rejected or challenged by the asset owner.
✗
AEMS records incomplete: PTI photos captured on device but never pushed to the shipping line's maintenance system — creating a documentation gap that surfaces as a compliance issue during audits.
✗
Technician departure loses records: Months of PTI photos stored on a personal device or in a private WhatsApp thread become permanently inaccessible when a technician leaves or changes role.
✗
Manual distribution consumes hours weekly: Office staff spend hours per week selecting, compressing, and emailing PTI photo sets that a structured system would distribute automatically in seconds.
✗
Shipping line disputes unresolvable: Without a verified timestamp and GPS location at capture, a shipping line can challenge whether the PTI was conducted at all — with no audit trail to prove otherwise.
With structured digital PTI documentation, every inspection creates a complete, timestamped, container-linked record — spare part serial numbers included — distributed automatically to the correct recipient and stored permanently in a searchable archive. The next time a warranty claim or shipping line dispute arises, the evidence is there in seconds.
No hardware required. No implementation project. Your technicians can be capturing structured PTI photos on day one.
