Port Terminal, Inland Container Depot (ICD) & Empty Container Depot ERP: IICL-6 Gate Survey, 3D Reach-Stacker Yard Slot Mapping, Reefer Plug Monitoring & Storage Tariff Billing

Inland Container Depots (ICDs), Container Freight Stations (CFS), and Empty Container Depots along the Northern Corridor (Mombasa, Mariakani, Nairobi Embakasi/Syokimau, Naivasha, Kisumu, and Kampala) handle thousands of 20ft (TEU), 40ft (FEU), High-Cube, and Reefer containers daily for global shipping lines. Operating a container yard on spreadsheets or legacy desktop tools leads to costly reach-stacker re-handling ("shuffling" 4 containers to reach 1 buried box), unbilled IICL container repair damages, missed shipping-line EDI messages (CODECO / COARRI / DESTIM), and revenue leakage on progressive storage, lift-on/lift-off (LOLO), and reefer PTI/plug-in charges.

At devManue, we engineer high-throughput Terminal Operating Systems (TOS) & Empty Container Depot ERP platforms featuring ISO 6346 container number validation, tablet-based IICL-6 Gate-In Equipment Interchange Receipts (EIR), 3D Block-Bay-Row-Tier yard slot optimization, automated shipping-line EDI gateways, and instant M-Pesa/bank LOLO + storage gate-release billing.

1. Eliminating Yard Re-Handles, Unbilled M&R & Gate Congestion

• Tablet IICL-6 Gate-In Damage Inspection & CEDEX Repair Estimating: Gate inspectors walk around the arriving truck with rugged tablets, validating the ISO 6346 11-character container number (including modulo-11 check digit), capturing CSC plate validity, and tapping structural damage zones (floor gouges, corner-casting cracks, door gasket tears, dent depths) using standard IICL-6 / CEDEX component, damage, and repair codes—instantly transmitting repair estimates (EDIFACT DESTIM) to the shipping line for approval.
• 3D Bay-Row-Tier Yard Slot Assignment & FIFO Shipping-Line Segregation: Reach-stacker and empty-handler operators receive real-time cab tablet instructions showing the exact Block-Bay-Row-Tier coordinate to stack or retrieve containers—segregating boxes by shipping line, size/type, food-grade vs. cargo-worthy status, and Machinery/Workshop repair hold.
• Reefer Pre-Trip Inspection (PTI) & Power Plug-In Telemetry: Tracks exact plug-in and unplug timestamps, set-point vs. return-air temperatures, and automated daily kWh/plug-in tariff billing.

2. ISO 6346 Check-Digit Validator & Progressive TEU/FEU Storage Tariff Engine

Our Terminal Operating System validates ISO 6346 container numbers at the gate and computes multi-tier progressive storage, lift-on/lift-off (LOLO), washing, and reefer PTI/power charges to the exact calendar day:

3. Automated Shipping-Line EDIFACT (CODECO, COARRI, DESTIM) & SFTP Gateways

Every Gate-In, Gate-Out, Repair Estimate, and Repair Completion triggers real-time or scheduled 15-minute UN/EDIFACT CODECO and DESTIM transmissions to shipping lines (Maersk, MSC, CMA CGM, ONE, Hapag-Lloyd, PIL, Cosco), keeping global equipment control systems 100% synchronized with your physical yard.
