Why are ships used more than planes?

Why Ships Still Dominate Global Trade Despite Advances in Aviation

Despite the advent of air transport, ships remain the primary means for transporting goods across vast distances. There are several compelling reasons for this continued dominance:

Economical Advantage:

Ships offer significant cost advantages for bulk cargo shipments. They are designed to carry massive volumes of heavy goods, making them highly efficient for transporting commodities such as raw materials, manufactured components, and finished products. Airplanes, on the other hand, are more suited for high-value or perishable goods that require faster delivery.

Lower Operational Costs:

The operational costs for ships are generally lower than for planes. Fuel consumption is a major expense for both modes of transport, but ships consume less fuel per unit of cargo carried. Additionally, ships can travel at slower speeds, reducing energy expenditure.

Capacity and Range:

Ships have a much greater capacity than planes, allowing them to transport large quantities of cargo in a single voyage. This is particularly important for industries that require massive volumes of raw materials, such as the energy and construction sectors. Ships also have a longer range than planes, enabling them to cross oceans without the need for refueling or stopovers.

Environmental Impact:

Although ships emit greenhouse gases, their carbon footprint per ton of cargo is significantly lower than that of planes. This is due to their larger carrying capacity and more efficient fuel consumption. As concerns about environmental sustainability grow, ships are likely to remain a more eco-friendly option for international freight.

Complementarity with Air Transport:

While ships dominate global trade, air transport does play a complementary role for time-sensitive or high-value goods. Airplanes can reach distant destinations faster, making them ideal for perishable goods, sensitive equipment, and urgent shipments. This complementarity ensures that both modes of transport serve different niches in the logistics industry.

Conclusion:

Despite advancements in aviation, ships continue to be the preferred choice for global trade due to their cost efficiency, capacity, range, and environmental advantages. Their ability to transport vast quantities of heavy goods across oceans economically makes them indispensable for the global economy. While air transport plays a vital role for time-sensitive or high-value goods, ships are expected to maintain their dominance in international freight for the foreseeable future.
