Before and After Documentation for Container Wash Stations
Trusted by container depots, shipping lines, and leasing companies across Europe. Manual wash documentation leaves depots exposed to disputes and failed audits. Each wash cycle becomes a structured, timestamped, and searchable record — linked to container ID and ready to share with shipping lines instantly.
What Is a Container Wash Station Documentation System?
A container wash station documentation system is a structured digital workflow that captures photographic evidence of container condition before and after washing, links each image to a validated container number, and stores records in a centralised, searchable archive. It replaces informal capture methods — WhatsApp, shared folders, email chains — with a centralized, searchable archive of timestamped wash records.
ConPDS delivers this as a purpose-built platform for container operations. Checker OCR reads the container number and verifies the ISO 6346 check digit; wrong recognition is flagged for retake or manual entry. Mobile capture retains the timestamp and can include device-recorded location when enabled and available as context.
Captures exterior and interior condition before and after every wash cycle
Container number linked via on-device AI-powered OCR — wrong recognition flagged, with a retake-or-manual-entry fallback
Capture timestamp retained; device-recorded location included when enabled and available as context
Records stored centrally and searchable by container number in seconds
Photo sets distributable to shipping lines via guest portal, email, FTP, or API
A wash certificate without supporting photo evidence is a statement. Without a structured wash-bay photo record system, wash stations face a set of documentation failures that are invisible during daily operations — but become critical the moment a shipping line raises a dispute or an audit request arrives.
A wash station processing 80 containers per day generates over 320 photos across pre- and post-wash steps. Without automatic linking, photo retrieval during disputes becomes unworkable — folder sorting and filename guessing break at this scale.
Documentation Failures
Before and after photos scattered across personal devices, chat threads, and shared folders
Manual folder naming errors make historical records permanently unfindable
Photos transferred via WhatsApp are organised around people and threads, not validated container numbers or retention policy
No link between photo and specific container number — matching depends on memory
Operational Consequences
Shipping lines challenge whether the wash was completed to the required standard
Pre-existing damage misattributed to the wash station when no pre-wash record exists
Staff departure makes entire wash record histories inaccessible overnight
GDPR exposure from inspection data residing on personal devices and unsecured apps
With manual methods: a shipping line disputes wash quality three weeks after service. The wash station cannot locate the pre-wash interior photos or confirm which technician performed the work — the claim is upheld and the depot absorbs the cost.
With structured before/after wash evidence: the before-and-after set is linked to the container number and searchable in the central archive. The capture timestamp is retained; device-recorded location can be included when enabled and available as context.
How Structured Wash-Bay Photo Records Work in Practice
Four structured steps replace the informal capture-and-file approach with an automatic, auditable wash record for every container that passes through your facility.
01
Pre-Wash Capture
OCR links photos to container
02
Defect Documentation
Pre-existing damage recorded
03
Post-Wash Capture
Cleaning confirmed, linked to record
04
Share Proof-of-Service Automatically
Share via portal, email, or API
STEP 01
Photograph Pre-Wash Condition with AI-Linked OCR
On container arrival, field staff photograph exterior and interior condition using Checker. On-device OCR verifies the ISO 6346 check digit; wrong recognition is flagged for retake or manual entry. The capture timestamp is retained, and device-recorded location can be included when enabled and available as context.
STEP 02
Document Pre-Existing Defects
Any structural damage, contamination, or components identified as requiring attention before or during the wash are photographed in detail and added to the same container record. This establishes a defensible pre-wash baseline, documented and time-stamped, to protect your station from downstream blame.
STEP 03
Capture Post-Wash Condition
After the wash is complete, interior and exterior post-wash photos are captured under the same container record. The full before-and-after set is stored centrally in the ConPDS dashboard and remains searchable by container number within the configured retention period.
STEP 04
Share Proof-of-Service Under Configured Rules
The complete photo set can be downloaded and attached to a wash certificate, accessed through the ConPDS guest portal, or sent to shipping lines by email or FTP when a tenant distribution rule is configured. Rules can run immediately or after a configured delay, and every attempt is logged with success or failure.
Container Inspection Workflows Specific to Wash Station Operations
Wash station container inspection differs from standard depot gate-in documentation in one critical respect: the same container must be documented twice — before the wash begins and after it is complete — with both sets linked to a single, retrievable record. The following detail defines exactly what gets captured at each stage.
EXTERIOR PRE-WASH
photo_camera Pre-Wash Exterior Documentation
All exterior surfaces photographed on arrival — recording existing dents, damage, contamination, and identification markings. Establishes the container's condition before any wash activity begins and protects the station from liability for pre-existing damage.
INTERIOR PRE-WASH
search Pre-Wash Interior Documentation
Interior surfaces, floor condition, and any residue or contamination photographed before washing. Particularly relevant for ISO tank containers and food-grade units where prior cargo evidence must be clearly recorded before the cleaning cycle.
DEFECT & REPAIR
build Defect and Repair Identification
Components identified as requiring attention during the wash process — damaged door seals, structural defects, or parts requiring replacement — are photographed and added to the container record. This creates a documented repair referral trail linked directly to the wash event.
POST-WASH
check_circle Post-Wash Interior and Exterior
A full new photo set captured after the wash is complete — confirming interior surfaces have been cleaned to the required standard and exterior condition following the process. These images, paired with the pre-wash set, constitute the structured before and after wash record.
Why this matters
A wash certificate supported by a timestamped, container-linked before and after photo record carries a fundamentally different evidentiary weight than an administrative document alone. When a shipping line or leasing company queries wash quality weeks after service, the ConPDS record answers that claim with a searchable, timestamped photo record — not just a certificate or statement.

lock
EU-hosted secure archive
Photos are stored encrypted on the device until upload, with a local copy retained for about seven days after successful upload. The central archive applies role-based access controls.
Compliance and Security for Wash Station Photo Records
Inspection documentation at wash stations carries specific compliance requirements — particularly when containers are processed for food-grade, ISO tank, or hazardous cargo customers where cleaning certificates must be supported by verifiable photo evidence.
Every photo capture, distribution event, and access action is timestamped and logged automatically — including photo edits (with the original retained for recovery), tags, notes, and later changes to those fields
Container numbers are validated on-device against the container number standard (owner code, serial number, and check digit) at the moment of capture, including offline — wrong recognition is flagged for a retake or manual entry, reducing mislinked wash records
Every portal login, container search, and photo download by external parties is logged in full — including user ID, container ID, and timestamp
Encrypted local copy retained about seven days after successful upload; central archive remains authoritative
Frequently Asked Questions — Wash Station Photo Records
What is a container wash station documentation system? ▲
A container wash station documentation system is a structured platform that captures before and after wash photos, links each image to a validated container number, and stores records centrally for instant retrieval and distribution. It replaces WhatsApp threads, email attachments, and shared folders with a single auditable system that produces timestamped proof-of-service records.
Does ConPDS replace our existing Depot Management System? ▲
No. ConPDS adds the structured photo evidence layer your current DMS or M&R system is missing, without replacing or disrupting it. Integration is supported via REST API, FTP, SFTP, and email — connecting to existing depot management and shipping line systems including EOS, DepotMaster, and Maersk AEMS. If your system is not yet supported, we will add the integration on request. See the Checker integrations page for the full list.
Does the system work offline in the wash bay? ▲
Yes. ConPDS Checker runs fully offline — AI-powered OCR for container number reading and all core capture functions operate on-device without a network connection. Photos are stored securely on the device and sync automatically once connectivity is restored.
Is wash station photo documentation privacy-by-design? ▲
Yes. Photos are stored encrypted on the device until upload, and a local copy is retained for about seven days after successful upload. HTTPS encrypted transport and role-based access controls protect the central archive.
Can we document both interior and exterior condition at the wash station? ▲
Yes. Exterior and interior, pre-wash and post-wash photos can be linked to one container record. Checker retains the capture timestamp and can include device-recorded location when enabled and available; location is context, not independent proof of presence.
Can wash photo records be shared directly with shipping lines? ▲
Yes. The ConPDS guest portal gives external parties scoped access to permitted container records. When a tenant distribution rule is configured, Checker can send full photo sets via email, FTP, or SFTP immediately or after a configured delay, and every attempt is logged with success or failure.
How quickly can our wash station team get started? ▲
Your team can be capturing structured before and after wash photos within days of onboarding — ConPDS Checker runs on the smartphones your staff already carry. Setup, configuration, and onboarding support are all included in the subscription, with no separate implementation charges.
Ready to Replace Scattered Wash Records With Structured Documentation?
Every undocumented wash cycle leaves a gap in your proof-of-service — one that a dispute or audit could turn into liability.
What Happens Without Structured Wash Documentation
✗No pre-wash baseline: damage found after the wash is attributed to the station with no photographic evidence to contest the claim.
✗Unverifiable cleaning standard: shipping lines dispute wash quality weeks after service — a wash certificate without photo evidence cannot resolve it.
✗Lost records on staff departure: wash histories stored on personal devices or WhatsApp become inaccessible the moment an employee leaves the business.
✗Failed compliance review: no retrievable audit trail for wash events means GDPR and insurance audit requests cannot be answered with verifiable records.
✗Manual retrieval failure: at 80+ containers per day, searching shared folders for a specific container's wash photos from three weeks ago is operationally unworkable.
ConPDS gives your wash station a structured photo evidence workflow that captures before and after condition automatically, links every photo to the correct container record, and distributes proof-of-service directly to shipping lines — with nothing to install and full setup support included.
