As the most important branch of international logistics, maritime transport supports economic development by providing access to raw materials, finished products, and other goods essential to the global supply chain.
What Is Maritime Transport?
Maritime transport is a branch of transportation that involves the movement of goods by sea using various types of ships between ports worldwide. It is utilized for transporting a wide range of cargo, including containers, bulk goods, and specialized oversized loads. Due to its capacity to carry large quantities of goods over long distances, this mode of transport is the backbone of global trade.
Types of Maritime Transport
Maritime transport encompasses several types of shipping, depending on the type of cargo and the specifics of the transport. These include container shipping, bulk cargo transport, liquid bulk transport, and smaller breakbulk cargo shipments.
Maritime transport can also be classified based on the geographical scope of operations: international, domestic, and coastal shipping.
Each type of maritime transport requires specific types of ships, such as container ships, bulk carriers, tankers, or breakbulk vessels.
Container Ships
Container ships are vessels specialized in the transport of containers, which can hold various goods, including food products, electronics, vehicles, or raw materials. Container transport is the most popular form of maritime shipping due to its efficiency and the ease of handling containers in ports. Container capacity is measured in TEUs (Twenty-foot Equivalent Units), which corresponds to the volume of a 20-foot long container. In container transport, we distinguish between:
- FCL (Full Container Load): where the entire container is used by a single customer.
- LCL (Less Container Load): where the container space is shared among multiple customers, reducing costs.
Bulk Carriers
Bulk carriers are ships designed to transport bulk cargo, such as coal, iron ore, or grain. Their construction allows for the movement of large quantities of homogeneous goods, which is advantageous for long-distance transport. Bulk carriers are a crucial component in the global transportation of raw materials.
Tankers
Tankers are specialized ships used to transport liquid cargo, such as crude oil, gas, or chemicals. With special tanks and safety measures, tankers enable the safe transport of cargo over long distances. They are essential in the global trade of oil and other energy resources.
General Cargo Ships
General cargo ships are used to transport non-bulk cargo. They can carry various goods, from machinery to furniture, often in smaller quantities. These ships are more flexible in handling different types of cargo and can dock at smaller ports where larger vessels have no access.
Advantages of Maritime Transport
Maritime transport has many advantages, making it the dominant mode of transport in global trade. It is no surprise that it handles the largest share of goods transport worldwide, accounting for 80% of total international trade. Thanks to its cost-effectiveness, ability to carry vast amounts of cargo, and energy efficiency, maritime transport forms the backbone of global logistics and plays a key role in connecting markets and economies worldwide. The benefits of this type of transport include:
Cost-Effectiveness
Maritime transport is considered one of the most economical means of transporting goods, especially over long distances. The cost of shipping a sea container is usually lower than other modes of transport, such as air or road. This is due to the ability to carry large quantities of goods simultaneously, which reduces the unit cost of transport. Additionally, the relative low fuel costs contribute to its popularity.
Large Capacity
Marine vessels, particularly container ships and bulk carriers, are characterized by their large capacity. They can carry thousands of containers (measured in TEU), allowing the transport of vast quantities of goods in a single voyage. The largest container ships can carry up to 20,000 TEU. The large capacities of marine vessels make them ideal for transporting bulk cargoes, such as natural resources, grain, crude oil, or coal, as well as consumer goods on a global scale.
Energy Efficiency
Maritime transport is more energy-efficient compared to other modes of transport, such as air or road. Marine vessels consume less fuel per ton of cargo transported, which translates to lower carbon emissions per unit of cargo. Long sea routes also allow for more efficient use of energy, making maritime transport more environmentally friendly. The growing importance of energy efficiency in global logistics makes maritime transport an attractive option for companies concerned with sustainable development.
Versatility
Maritime transport is incredibly versatile, meaning it can carry various types of cargo. From containers containing consumer goods, bulk cargoes, to specialized liquid cargoes in tankers, transport can handle almost any type of cargo. Moreover, with a well-developed port infrastructure, goods can be transported to almost any location on the globe. Maritime transport also supports the development of multimodal transport, allowing seamless connection with other modes of transport, such as rail or road, enabling the direct delivery of cargo to its final destination.
Disadvantages of Maritime Transport
Despite numerous advantages, maritime transport has its disadvantages, which can impact the efficiency and cost of transportation. Key issues include slow delivery speed, dependency on weather conditions, and limitations related to port infrastructure. These factors can lead to delays, increased costs, and difficulties in supply chain management.

Ports may have limited capacity to handle large vessels due to their depth, infrastructure, and available loading and unloading equipment. Problems such as narrow port entrances, lack of appropriate container terminals, or overloaded infrastructure can lead to delays and increased operational costs. Long queues for loading and unloading, as well as limited space for cargo storage, can also affect the passage time through ports and the efficiency of the entire logistics process.
Key Players in Maritime Transport
Ports and canals are essential links in the global maritime transport system, playing key roles in efficiently managing the flow of goods. Ports act as logistics centers where cargo is transferred between ships and other modes of transport, such as trains and trucks. The world's largest ports, such as Rotterdam, Singapore, or Shanghai, are crucial points in the global supply chain, handling vast amounts of containers and bulk cargo. They have advanced infrastructure, including container terminals, port cranes, and warehouses, allowing for fast and efficient cargo handling. The situation in the Suez Canal during the 2021 blockage clearly demonstrated how critical sea canals are for global transport. The blockage of this strategic route caused serious disruptions in the supply chain and global trade, highlighting the importance of maintaining the smooth flow of goods between continents. The Suez Canal, connecting the Mediterranean Sea with the Red Sea, is one of the most important sea routes, and its significance for international transport is invaluable. Incidents like this show how essential canals are for the efficiency and stability of global logistics.
