A look into the world of Sea Transportation

Sea transportation has been one of the most widely used methods of transporting goods over long distances for centuries. Today, much of international trade takes place by sea, with ships providing enormous capacity for moving goods around the world.

What is sea transport?

Maritime transport refers to the transportation of goods by sea using ships. This type of transportation is used to move goods from one port to another, both within the same country and internationally.

In marine transportation, goods are usually loaded into containers, which are then placed on large cargo ships. These containers can hold a wide range of products, ranging from consumer goods such as clothing and electronics to heavy machinery, raw materials and even liquids such as oil and chemicals. The use of standardized containers provides simplicity in loading, unloading and moving goods, which contributes to the efficiency of marine transportation.

There are different types of ships used in marine transportation, depending on the type of cargo being transported. For example, container ships are used specifically for carrying containers, while bulk carriers are used for unpackaged goods such as grain or ore. There are also tankers for liquids and RORO ships for vehicles.

Sea transportation allows companies to ship their goods around the world at a relatively low cost. Although transportation by sea can take more time than other forms of transportation, such as air freight, the cost savings and ability to transport large volumes make it an attractive option for many companies.

Benefits of Sea Transportation

1. Cost savings: Sea transportation is often the most cost-efficient way to transport large quantities of goods, especially compared to air freight. Unit costs drop significantly when you ship in bulk, allowing companies to save money on transportation costs. This is particularly beneficial for companies shipping low-margin goods or high-volume products.
2. Suitable for large volumes: Ships have a huge cargo capacity, making them ideal for transporting large volumes of goods. This is especially useful for companies looking to ship products in bulk, such as raw materials, machinery, and consumer goods. The economies of scale of ocean transportation allow companies to operate efficiently and cost-effectively.
3. Global reach: Maritime transportation provides access to nearly every destination worldwide. With an extensive network of ports and routes, companies can ship their goods almost anywhere in the world. This global reach makes it possible to enter new markets and expand existing ones, contributing to a company's growth.

Disadvantages of Sea Transportation

1. Longer transportation times: One of the biggest disadvantages of ocean transportation is the longer delivery time compared to other transportation methods, such as air freight. Depending on the distance and route, it can take weeks for goods to reach their destination. This means companies must plan their inventory management carefully to avoid delays.
2. Complexity of logistics: Coordinating sea transport can be complex, especially if there are multiple intermediate steps, such as transshipment at different ports. Planning requires a detailed approach to ensure that everything runs smoothly. Factors such as customs formalities, port tariffs, and ship availability can have a major impact on the efficiency and cost of transportation.
3. Environmental impact: Although ships are efficient in terms of quantity transported per unit of fuel, they still contribute to greenhouse gas emissions and other pollutants. This can be a concern for companies striving for sustainability and a smaller environmental footprint. Fortunately, there are initiatives and technologies under development to reduce the environmental impact of marine transportation.

Types of Sea Transportation

Sea transportation includes various methods of transporting goods across the ocean, each tailored to specific types of cargo. The choice of a particular type of ocean transport depends on the nature of the goods, the destination, and the requirements for speed and safety.

1. Container transport: Container transport is the most common form of sea transport for goods. Containers are standard sizes that can be easily transferred between ships, trains and trucks, making them ideal for intermodal transportation. This type of transportation offers flexibility and security, as goods are safely stored in locked containers during transit.
2. Bulk transportation: bulk transportation is used to transport unpackaged goods in large quantities, such as grain, coal, oil, and minerals. There are two main types of bulk transportation: dry bulk and liquid bulk. Dry bulk includes products such as grain and ore, while liquid bulk refers to liquids such as oil and chemicals.
3. RORO transport: RORO (Roll-on/Roll-off) vessels are specially designed for transporting vehicles, such as cars, trucks, and heavy equipment. In this method, vehicles are easily driven onto and off the vessel, which ensures efficient loading and unloading. RORO transportation is popular among car manufacturers and companies that need to ship large vehicles.

Cost of Sea Transportation

The cost of marine transportation is affected by several factors, including:

• Distance and route: The longer the distance and the more complex the route, the higher the transportation costs. Ports with limited access or routes through geopolitically sensitive areas may incur additional costs.
• Type of goods: The type of goods affects costs. Dangerous or perishable goods require special handling and provisions, which can increase costs.
• Seasonal fluctuations: Demand for marine transportation can vary depending on the season, which affects prices. For example, during harvest season, demand for bulk transportation may increase, driving up costs.

Port and customs fees: Port fees, customs duties and taxes are additional costs that must be considered. These may vary depending on the destination and type of goods being shipped.
