| Protection Level | Moderate – exposed decks increase moisture/salt exposure | Low – loose stowage increases contact and chafing risk | High – full enclosure (if covered) and controlled lashings |
| Transit Time (China → Middle East / Africa / Americas) | 18–25 days | 22–30 days | 20–26 days |
| Cost per Shipment (20 units) | $3,800–$4,500 | $2,900–$3,300 | $3,600–$4,200 |
| Insurance & Risk | Medium (weather-exposed decks) | High (shifting, moisture, poor stacking) | Low to Medium (controlled environment possible) |
| Port Infrastructure Requirements | RO-RO terminal mandatory | Standard bulk terminal | Standard container terminal |
| CO₂ Emissions (Relative) | Medium | Low | Medium-High |
| Best For | Not recommended | Budget shipments with high volume | High-value, corrosion-sensitive equipment |
Recommendation: Flat Rack is the optimal method for PTO-driven hydraulic pumps due to superior cargo control, compatibility with export crating, and reduced mechanical risk. RO-RO is impractical. Bulk cargo is cost-effective but unsuitable for corrosion-sensitive shipments without additional protection.
4. Corrosion Protection: Wax Spraying System
To mitigate seawater-induced corrosion during ocean transit, SEA LION International mandates the application of industrial-grade rust preventative wax spray as a standard pre-shipment procedure.
Wax Spraying Protocol (Per ISO 20747:2021)
| Parameter | Specification |
|---|---|
| Wax Type | Solvent-based, hydrophobic petroleum wax (e.g., Henkel Techniclean 805) |
| Application Method | Automated spray booth, 360° coverage |
| Film Thickness | 25–35 µm (uniform layer) |
| Coverage Areas | All exposed ferrous surfaces, mounting flanges, shaft ends, vent plugs |
| Drying Time | 45 minutes @ 25°C |
| Salt Spray Resistance (ASTM B117) | >500 hours |
| Removal Method | Biodegradable degreaser (post-delivery) |
Benefits:
- Forms hydrophobic barrier against salt-laden air and condensation
- Self-healing properties under minor abrasion
- Compatible with VCI packaging systems
- No impact on pump tolerances or seal integrity
Note: Wax application is required for all shipments via Bulk and Flat Rack. RO-RO units, if shipped, must receive double-layer protection.
5. Recommended Export Workflow
- Pre-Treatment: Clean and dry pump assemblies; apply wax spray in climate-controlled facility.
- Packaging: Seal in VCI-lined wooden crate with silica gel desiccants.
- Shipping Mode: Flat Rack container (20’ or 40’), lashed and secured.
- Documentation: Include corrosion protection certificate, packing list, and ISO-compliant test reports.
- Port Handling: Use enclosed storage pre-loading; avoid open-yard stacking.
- Destination: Final inspection and wax removal prior to integration.
6. Conclusion
For reliable, high-integrity export of PTO-driven hydraulic pumps from China, Flat Rack shipping combined with industrial wax spraying offers the optimal balance of protection, cost, and logistical control. Bulk Cargo may be considered for non-critical, high-volume orders with enhanced packaging. RO-RO is not advised due to incompatibility with component-level cargo.
SEA LION International enforces wax protection as standard across all export batches to ensure operational readiness upon delivery to fleet maintenance depots and construction sites.
