The IMO SOLAS Verified Gross Mass (VGM) regulation remains one of the most strictly enforced compliance requirements in global container shipping. Marine terminal operators at ports such as Los Angeles, Long Beach, Savannah, and Newark routinely reject containers that arrive without a certified VGM transmitted at least 24 hours prior to the vessel cutoff. The resulting vessel roll, demurrage, and rebooking costs routinely exceed $2,000 per incident and create cascading delays across drayage fleets running on tight port turn schedules.
For carriers operating Truckmate, McLeod, or TMW systems, the manual coordination between driver scale tickets, broker booking desks, and ocean carrier EDI requirements creates persistent points of failure. Strong Tower Consulting has developed a purpose-built compliance architecture that closes this gap through automated ingestion of certified CAT scale tickets and direct electronic submission of verified weights.
The SOLAS VGM Gate Lockout
When a drayage driver arrives at a marine terminal pedestal without a previously transmitted and accepted VGM, the terminal operating system immediately rejects the move. This triggers a sequence of costly events: the container is rolled from the booked vessel, storage charges begin to accrue, and the steamship line issues a misdeclaration penalty. In high-volume corridors, these roll events can consume 8-14 percent of monthly margin when left unmanaged.
The root cause is rarely intentional misdeclaration. More often it is a breakdown in the hand-off between the shipper's packing list, the drayage driver's certified scale ticket, and the broker's manual entry into the ocean carrier's booking portal. CheckPoint was purpose-built to eliminate this failure mode.
The Strong Tower SOLAS-Clear Architecture™
Our solution combines three tightly integrated components that operate inside the existing TMS and dispatch workflow:
- Certified scale ticket OCR ingestion: CheckPoint (available at https://exspeeditecheckpoint.com/login.php) uses optical character recognition to read public CAT scale and certified weigh station tickets. The system extracts gross, tare, and net weights along with the official timestamp and scale certification number. Data is stored with immutable audit trails suitable for both SOLAS Method 1 and Method 2 declarations.
- Automated EDI 304 / VGM API transmission: Once the weight is certified, CheckPoint automatically generates and transmits an EDI 304 or API payload directly to the ocean carrier's booking desk. Transmission occurs a minimum of 24 hours before port gate cutoff, satisfying every major steamship line requirement.
- Drayage bridge formula validation: Before releasing the load to the driver, the system performs real-time federal bridge formula calculations across axle groups. This prevents overweight citations on both highway and rail segments that frequently serve port terminals.
Overturning Ocean Carrier Misdeclaration Penalties
When steamship lines assess excess weight or misdeclaration fines, the burden of proof falls on the cargo interest. CheckPoint produces tamper-evident, cryptographically signed weight dossiers that include the original scale ticket image, OCR-extracted values, certification metadata, and transmission logs. These records have successfully overturned more than $180,000 in disputed penalties for clients running McLeod or TMW dispatch systems during the past 24 months.
Integration With Existing Transportation Management Systems
CheckPoint was engineered to augment, not replace, your core TMS. Whether you run Truckmate SQL Server schemas, McLeod load and settlement tables, or TMW EDI 204/214/210 workflows, the platform ingests scale data via mobile upload or direct API from certified scales. Driver settlement calculations, fuel surcharge logic, and detention tracking remain untouched inside your primary system. The only change is the elimination of manual VGM entry and the resulting gate rejections.
