2. Structural Integrity & Handling Requirements

RO-RO

• Trucks are driven or towed directly onto the vessel.
• Secured using wheel chocks, lashing straps, and deck anchors.
• Minimal handling reduces mechanical stress.
• Requires functional braking and steering systems.

Flat Rack

• Ideal for non-operational or damaged units.
• Trucks lifted by crane and secured to flat rack container (20′ or 40′).
• Lashing points must be structurally sound.
• Exposed to weather; requires full protective treatment.

Bulk Cargo

• Trucks stacked without containment.
• High risk of impact damage and saltwater immersion.
• Not compliant with OEM or fleet resale standards.
• Not recommended for used commercial truck exports.

4. Recommended Export Protocol (SEA LION Standard)

1. Pre-shipment Inspection: Confirm OKC status (engine, transmission, brakes, tires).
2. Fuel & Fluid Management: Drain to 25% capacity; disable battery.
3. Wax Spraying: Full undercarriage treatment at approved depot.
4. Loading Method Selection:
5. Operational Units: RO-RO (preferred)
6. Non-operational Units: Flat Rack (40’ with lashing)
7. Documentation: Provide Bill of Lading, Condition Report, and Wax Application Certificate.

---

5. Conclusion & Recommendations

• RO-RO is the optimal method for operational used trucks, offering superior protection, faster turnaround, and lower insurance premiums.
• Flat Rack is acceptable for non-running units but requires full corrosion protection and higher handling costs.
• Bulk Cargo is not recommended due to unacceptable risk profiles.
• Wax spraying is non-negotiable for all shipments; omission voids transit warranty.

Fleet managers and construction firms should standardize on RO-RO logistics with certified wax protection to ensure equipment arrives in market-ready condition.
