4. Corrosion Protection: Wax Spraying Protocol

To mitigate seawater-induced corrosion during transit—particularly critical for electrical enclosures, hydraulic fittings, and carbon-steel frames—SEA LION International mandates the application of industrial-grade hydrophobic wax spray prior to shipment.

Wax Spraying Specification:

Parameter	Requirement
Product Type	Solvent-based, non-conductive corrosion inhibitor (e.g., Cosmoline VCI, Henkel AQUENCE)
Application Method	Pressurized spray + brush detailing on joints
Coverage Areas	All exposed ferrous metals, bolt heads, undercarriage, transformer casing
Thickness	50–75 µm (uniform film)
Drying Time	4–6 hours (ambient 25°C, 50% RH)
Removability	Biodegradable solvent wash (post-delivery)
Certification	ISO 9227 Salt Spray Test (passed 500h NSS)

Compliance Note: Wax-treated units must be documented with pre-shipment inspection reports (SGS or Bureau Veritas) to validate coating integrity.

---

5. Recommendation

For the export of excavator transformers from China, Flat Rack container shipping is the optimal solution due to:

• Superior structural support and load distribution
• Compatibility with wax-protected, non-weatherproof units
• Reduced handling risk vs. RO-RO or bulk
• Seamless integration with global intermodal networks

RO-RO is conditionally viable only if the unit is fully operational and wax-protected, but poses higher exposure risk.
Bulk Cargo is not recommended due to uncontrolled environmental exposure and elevated corrosion/insurance liabilities.

---

6. Operational Workflow (Flat Rack Export)

1. Pre-shipment wax application & drying (72h lead time)
2. Load-out at factory via mobile crane onto 40’ Flat Rack
3. Lashing & securing per CSC & IMO CSS Code
4. Truck transport to port (Ningbo/Shanghai)
5. Vessel stowage on weather deck with tarpaulin cover
6. Transit with humidity monitoring (optional IoT loggers)
7. Final inspection & wax removal at destination depot

---

7. Conclusion

Excavator transformers require logistics solutions that balance cost, protection, and reliability. While RO-RO and bulk options present lower nominal freight costs, their exposure risks and compatibility limitations make them unsuitable for high-integrity electrical-hydraulic systems. Flat Rack shipping, combined with industrial wax corrosion protection, delivers the highest assurance of equipment readiness upon arrival—critical for time-sensitive construction deployments.

SEA LION International endorses Flat Rack + Wax Spray as the standard specification for all excavator transformer exports from Q2 2026 onward.
