Container Operational Evidence: Definition and Workflow
Container operational evidence is the defensible, container-linked record of every inspection, repair, lease return, gate event, PTI, and wash that has happened to a container — captured during the operation, retained under operator-controlled policies, and produced on demand for the disputed charge, the lessor audit, the M&R dispute, and the compliance review. The platform that produces it is the evidence infrastructure underneath the depot, the workshop, the wash bay, and the gate. People still type "container operational evidence" into Google when looking for it — that is the popular phrase for the same category, just framed at the wrong altitude.
What Is Container Operational Evidence?
Why Informal Documentation Becomes Operational Risk
Most depots, workshops, and gates handling dozens of containers daily rely on informal methods for inspection records. A depot processing 80 containers per day generates 480+ images daily — without container-linked capture and an audit-logged chain, retrieval failure becomes statistically inevitable. A disputed repair without defensible evidence becomes a direct operational cost; a contested gate-out without a container-linked record becomes a charge the depot cannot recover. Each informal method creates a specific, documented failure mode.

How the Operational Evidence Layer Works in Practice
How Is Container Operational Evidence Captured in the Field?
Field technicians use the ConPDS Checker mobile application to capture container records directly at the depot, terminal, port, workshop, or wash bay. Checker reads ISO 6346 container numbers via AI-powered OCR, links every photo, video, and audio note to the correct container record, and syncs to the central platform — fully offline-capable. It works across all major container number layouts in all lighting conditions and container wear states. Technicians can capture up to 30 seconds of video or spoken audio commentary per container, providing context that static photos alone cannot convey — critical for reefer compressor checks, repair findings, and damage walk-throughs.
How Is Each Record Validated Against the Container Number Standard?
Container number validation occurs at the moment of capture — not during manual upload or filing. The system checks the OCR-read number against ISO 6346 standards (owner code, serial number, and check digit) before accepting the record. Every image is linked to the correct container at capture, with GPS location and timestamp preserved and not stripped at any point. Up to 10 manual post-processing steps — renaming, reformatting, resizing, and uploading — are automated and applied according to the receiving customer's formatting requirements.
How Is the Evidence Retained on Terms the Operation Controls?
All validated records are retained in a cloud-based dashboard accessible from any browser, hosted in EU infrastructure under GDPR compliance. Office staff search by container number, depot, date range, or inspection type. Every container builds a permanent, chronological evidence record — photos, video, and audio together — under granular role-based access controls and configurable retention periods. The end-to-end audit log of every capture, access, and distribution event cannot be modified without trace. Defensibility is structural, not dependent on operational discipline.
How Is Evidence Produced on Demand for Customers, Lessors, and Auditors?
Rule-based distribution dispatches container-linked evidence to defined recipients — shipping lines, leasing companies, agents, M&R systems — immediately after every inspection, repair, or gate event, via email, FTP, SFTP, or API. Rules are configured once and every dispatch is logged in the same audit chain. External parties access records through the ConPDS guest portal — a scoped login showing only the records they have been granted permission to view. The platform integrates with existing Depot Management Systems (DMS) and Maintenance & Repair systems including EOS, DepotMaster, Maersk AEMS, CMA-CGM, IMARS, MSC OVMR, Hapag FIS, Saeco, Triton, and custom APIs. New integrations are added on request.
Where the Evidence Layer Is Used
The evidence layer supports every stage of the container lifecycle — from gate-in inspection through repair and PTI to lease return, M&R claim defence, and the lessor audit. These are the most common operational contexts where defensible, container-linked records replace informal methods.

Informal Methods vs. the Operational Evidence Layer
| Informal Method | Operational Evidence Layer |
|---|---|
| WhatsApp threads — metadata stripped, records lost when devices change, no audit log | Container-linked records with GPS and timestamp preserved at capture, ISO 6346 validated, audit-logged end to end |
| Manual file renaming — one typo makes a photo permanently unfindable | Automatic ISO 6346 container number validation at capture — no manual entry, no misfiling |
| Shared folders without structure — no enforced naming or organisation | Searchable container archive — find any container's full evidence history in seconds |
| Email distribution — no record of receipt, no delivery confirmation, no audit chain | Rule-based automated dispatch with full distribution audit trail per container event |
| Personal devices — months of records lost in a single personnel change, no central retention | Central cloud archive under business-controlled retention — every record retained regardless of staff changes |

Frequently Asked Questions
See the Evidence Layer in Practice
A shipping line disputes a container damage claim four months after gate-out. With informal methods, the depot searches email threads and shared folders — and cannot locate the gate-in record. With ConPDS, the full container history is retrieved in seconds and the dispute is resolved before it escalates. A disputed repair without defensible evidence becomes a direct operational cost; a defensible record turns it back into a closed file.
If the operation handles container inspection daily, a container-linked evidence layer reduces retrieval failures, eliminates manual filing errors, and creates defensible records for every claim, every audit, and every shipping-line review.
