| Sensitive Systems | Hydraulic cylinders, control valves, electrical panels, undercarriage |
| Corrosion Risk Zones | Undercarriage, weld joints, hydraulic fittings, unpainted steel surfaces |
3. SHIPPING METHOD COMPARISON
| Criteria | RO-RO | Bulk Cargo | Flat Rack (20’ or 40’ HC) |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed onto vessel | Craned into open hold; lashed on deck or in hold | Craned into secured flat rack container; lashed and braced |
| Suitability for Pontoon Excavators | High (if operational) | Low to Medium (risk of damage during loading) | High (optimal for disassembled or compact units) |
| Disassembly Required | Minimal (if self-propelled) | Often required for safe stowage | Recommended (pontoons detached, boom folded) |
| Cargo Protection | Limited (exposed to salt spray, weather) | Low (exposed to ballast water, humidity) | High (weatherproof tarping, controlled lashings) |
| Average Transit Time (China → Middle East / Africa / Latin America) | 18–26 days | 22–30 days | 20–28 days |
| Port Infrastructure Requirements | RO-RO ramp, clear access | Heavy-lift crane (>80T), open deck space | Standard container crane, flat rack availability |
| Average Cost (USD/unit) | $4,800 – $6,200 | $3,500 – $5,000 | $6,500 – $8,000 |
| Risk of Physical Damage | Medium (slippage, deck vibration) | High (sway, shifting, crane mishandling) | Low (if properly secured) |
| Customs Clearance Complexity | Low | Medium | Medium-High (container documentation) |
| Best Use Case | Functional units to RO-RO-equipped ports | Low-value, non-sensitive cargo; charter vessels | High-value units; corrosion-sensitive environments |
Note: Flat Rack containers allow partial enclosure and are ideal for oversized, non-stackable machinery. 40’ Flat Racks accommodate full pontoon sets with proper bracing.
4. CORROSION MITIGATION: WAX SPRAYING PROTOCOL
Seawater exposure during transit (humidity, salt spray, condensation) poses a critical risk to structural steel and hydraulic components. SEA LION International recommends industrial-grade wax-based anti-corrosion treatment as a mandatory pre-shipment procedure.
Wax Spraying Specifications (Per ISO 8501-1 & NORSOK M-501)
| Parameter | Requirement |
|---|---|
| Wax Type | Solvent-free, hydrophobic, self-healing microcrystalline wax (e.g., Cosmoline VCI, Henkel Techniclean 550) |
| Application Method | High-pressure spray (20–30 bar), full coverage of undercarriage, joints, cavities |
| Coating Thickness | 50–80 µm (measured via magnetic thickness gauge) |
| Coverage Areas | Undercarriage, pontoon interiors, hinge points, hydraulic cylinder rods (capped), weld seams |
| Drying Time | 4–6 hours @ 25°C; full cure in 24 hours |
| Post-Transit Removal | Biodegradable citrus-based solvent or steam cleaning (≤80°C) |
| Effective Protection Duration | Up to 12 months in marine environments |
Best Practice: Apply wax treatment 72 hours pre-loading in climate-controlled facility. Seal all air intakes, electrical enclosures, and cab vents with plastic wrap prior to spraying.
5. RECOMMENDED LOGISTICS STRATEGY
| Scenario | Recommended Method | Rationale |
|---|---|---|
| Fully assembled, operational unit; destination has RO-RO port | RO-RO | Fastest discharge, minimal crane dependency |
| High corrosion risk region (e.g., tropical coastal sites) | Flat Rack + Wax Spray | Enclosed transport, full corrosion control |
| Cost-sensitive project; inland destination with rail barge access | Bulk Cargo (with disassembly) | Lowest freight cost; use wax + desiccants in sealed pontoon cavities |
| Fleet shipment (≥5 units) | Mixed-mode: RO-RO for operational units; Flat Rack for sensitive models | Optimize cost and protection |
6. CONCLUSION
For pontoon excavator exports from China, Flat Rack containerization combined with industrial wax spraying offers the highest integrity and corrosion resistance, particularly for long-haul shipments to aggressive marine environments. While RO-RO provides speed and simplicity for functional units, and Bulk Cargo offers cost advantages, both present elevated risks to equipment longevity.
SEA LION International advises mandatory wax-based anti-corrosion treatment for all export units, regardless of shipping method, to ensure operational readiness upon arrival and minimize post-delivery maintenance.
