Water transport
I. DEFINITION
1. Container transportation
With standardized containers as the carrier mode of transport, the goods are concentrated into steel or aluminum alloy boxes, and the transport is completed by multimodal transport such as ships, railways and highways. Containers have a uniform size (such as 20 feet, 40 feet) and protective performance (weatherproof, seismic), suitable for industrial products, consumer goods, electronics and other high value-added or fragile goods.
2. Bulk cargo transportation
Do not rely on containers, directly stack bulk goods (such as coal, iron ore, grain, etc.) in the cabin for transportation. Bulk carriers are usually used, and the loading and unloading process relies on equipment such as clamps and conveyor belts, which is suitable for low-value-added goods without fine packaging.
II.CORE DIFFERENCES
1. Type of goods and packing requirements
- Container transport: suitable for standardized, protected goods (such as electronic products, daily necessities), the goods need to be prepackaged or fixed in the box.
- Bulk transportation: It is suitable for bulk commodities (such as ore, grain) without packaging, which are directly scattered in the cabin.
2. Handling efficiency and cost
- Container transport: high degree of mechanization, fast loading and unloading speed (such as 400-600 tons per hour), but additional container rental costs.
- Bulk transport: Complex and time-consuming loading and unloading (about 35 tons per hour), low efficiency, but lower transport unit price, suitable for large low-value goods.
3. Safety and cargo damage rate
- Container transportation: strong sealing, anti-theft, anti-damage (such as refrigerated containers can be kept fresh), the cargo loss rate is less than 1%.
- Bulk transportation: the goods are exposed to the environment (such as moisture, dust), loading and unloading is easy to cause damage, and the cargo loss rate is high.
4. Transportation network and route
- Container transport: Relying on global liner routes (such as the Far East-Europe route), the formation of a hub-and-spoke network, suitable for multinational transit.
Bulk cargo transport: mostly point-to-point fixed routes (such as Brazil to China iron ore route), routes concentrated and dependent on commodity origin.
5. Application scenario and economy
- Container transport: Scenarios with high value-added goods, door-to-door service or cold chain transport, with lower overall costs in the long run.
- Bulk transport: a single transport volume, low value and time requirements are not high scenario (such as energy, raw material trade).
III. Summary
With standardization and safety as its core advantages, container transport is suitable for high value-added goods in modern trade; Bulk shipping, with its low cost and flexibility, dominates the commodities sector. Selection should be based on the nature of the goods, transportation costs and supply chain needs. For example, the export of electronic products should choose container transport, while the coal trade is more suitable for bulk transport.
