• Limitation: Restricted to ports with RO-RO infrastructure (e.g., Dubai, Santos, Rotterdam).

Bulk Cargo – Cost-Driven, High Risk

• Use Case: Export of non-operational units for reconditioning.
• Risk Factor: High exposure to salt spray, rain, and mechanical damage.
• Mitigation: Mandatory wax spray + shrink-wrapping of cabs and intakes.

Flat Rack – Optimal for Oversized Units

• Use Case: Export of 35+ ton hydraulic excavators or custom configurations.
• Advantage: Full access for securing, compatibility with container logistics.
• Note: Requires lashing calculation per CSS Code (IMO).

---

6. Operational Guidelines for Fleet Managers

1. Pre-Shipment Audit: Verify excavator fuel level (<1/4 tank), battery disconnect, and track tension.
2. Wax Application: Conduct at origin facility; document coating thickness and coverage.
3. Documentation: Include IEC 60068-2-52 (salt mist test compliance) in export dossiers.
4. Port Coordination: Confirm terminal capabilities (e.g., crane capacity for FR units).

---

7. Conclusion

For fleet managers prioritizing equipment readiness and reduced downtime, RO-RO offers the optimal balance of cost and protection. Flat Rack is superior for non-standard or heavy-class excavators, despite higher costs. Bulk Cargo remains viable only under strict budget constraints and with full corrosion mitigation via wax spraying.

SEA LION International recommends integrating automated wax spraying lines at Chinese OEM facilities to standardize corrosion protection and ensure compliance with international marine transport codes.
