Packaging, Lashing, and Transport Procedures for Heavy-Lift and Out-of-Gauge (OOG) Cargo

Tan Cang Technical Services Joint Stock Company (Tan Cang Tech) is a trusted industry leader in multimodal transport of oversized and heavy-lift (OOG) cargo across inland waterways and coastal highways in Vietnam.

Backed by over 35 years of maritime engineering expertise and an extensive network of specialized equipment partners, Tan Cang Tech provides comprehensive, turnkey heavy logistics packages tailored to oversized industrial equipment, port cranes, transformer modules, and heavy project manufacturing lines.

Standard 5-Step Process for Heavy-Lift and OOG Cargo Logistics

1. Route Survey and Technical Feasibility Study

Prior to project mobilization, our marine and civil engineering specialists conduct thorough route surveys:

• Highway Route Surveys: Measuring vertical clearance under overpasses, toll plazas, overhead power cables, turning radius at intersections, and bridge load-bearing capacities.
• Waterway & Berth Surveys: Bathymetric depth sounding, tidal variation analysis, berth load limits, and navigational clearance under river bridges.

2. Engineering Calculations: Sea Fastening, Lashing & Stability

Using specialized simulation software, our technical team prepares rigorous method statements:

• Center of Gravity (CoG) and axle load distribution calculations.
• Lashing angle, turnbuckle tension, and chain rating design adhering to IMO Code of Safe Practice for Cargo Stowage and Securing (CSS Code).
• Barge ballasting sequence and hydro-static stability modeling for Ro-Ro loading and coastal transit.

3. Regulatory Permitting and Inter-Agency Coordination

Tan Cang Tech manages all specialized transport licensing, including oversized vehicle highway permits from the Ministry of Transport, maritime port authority clearances, and traffic police escort coordination.

4. Execution: Heavy Lifting, Ro-Ro Loading and Multi-Axle Transport

Mobilizing cutting-edge equipment including Self-Propelled Modular Transporters (SPMTs), multi-axle hydraulic lowbed trailers, heavy ballast barges, and high-capacity mobile cranes to execute roll-on, lashing, barging, and roll-off operations safely.

5. Delivery, Positioning, and Site Handover

Precision unloading, hydraulic jacking, skidding onto foundation plinths, and joint structural verification with the client before signing final project commissioning certificates.
