Problems, advantages, and disadvantages of international sea transportation: Water transportation, as one of the most important and oldest methods of goods movement, plays a vital role in international trade and logistics. Every year, billions of tons of goods are transported globally by ships. This method is highly favored by countries and major companies, like Jahān Tārābar, due to its high capacity, low cost, and lower environmental impact compared to other methods.
However, despite its many advantages, this method also faces numerous challenges and issues that can significantly affect the global supply chain and trade flow. This article explores the advantages and disadvantages of water transportation, as well as the challenges of international sea transportation, to provide a comprehensive perspective on this industry.
Challenges of International Water Transportation
Sea transportation faces several challenges, such as port congestion and delays in unloading and loading, which negatively affect scheduling. Additionally, capacity limitations and a shortage of containers can disrupt the movement of goods. Fluctuations in fuel prices also make the costs of this transportation method unpredictable. Furthermore, climate changes impact sailing conditions and increase weather-related risks. Finally, legal issues and international regulations complicate the enforcement of laws and agreements between countries.
Legal Issues and International Regulations
International maritime transport laws play a significant role in sea transportation. Changes in laws related to safety, the environment, and economic sanctions can create numerous challenges for shipping companies. Additionally, international sanctions against certain countries or companies can disrupt global trade flows, causing delays and increased costs.
Port Congestion and Delays in Unloading and Loading
One of the main issues in international sea transportation is port congestion. The increase in global trade has led many ports to struggle with a lack of sufficient space for unloading and loading goods. This issue can result in long delays and increased operational costs, disrupting the global supply chain. To solve this problem, ports need to invest in infrastructure and new technologies. The major commercial ports in Iran also face this challenge.
Capacity Limitations and Container Shortage
Another major issue is the capacity limitations of ships and the shortage of containers. Since the COVID-19 pandemic, the demand for goods transportation has significantly increased, but the available capacity to meet this demand is insufficient. This situation has led to higher transportation costs and difficulties in timely delivery of goods.
Fuel Price Fluctuations
Fuel is a key factor in the costs of sea transportation, and fluctuations in fuel prices can directly impact overall costs. With increasing pressure to use more sustainable fuels and reduce greenhouse gas emissions, shipping companies must invest in new technologies and environmentally friendly fuels, which increases costs.
Climate Change and Its Impact on Sea Transportation
Climate change is a significant issue in maritime transport. Rising sea levels, more intense storms, and other natural phenomena can threaten maritime infrastructure. These changes not only affect the safety of transportation but may also lead to higher maintenance and repair costs for ports and ships.
Advantages of Maritime Transport
Maritime transport is one of the most cost-effective and efficient methods for moving bulk and heavy goods. Due to its low fuel costs, high capacity, and lower energy consumption compared to other methods, it is considered an economic and sustainable option. Additionally, maritime transport has a lesser impact on environmental pollution and is seen as a suitable solution for reducing road traffic and improving access to remote areas.
Low Transportation Costs
One of the biggest advantages of maritime transport is its lower cost compared to other methods, including air and road transport. Due to its high capacity and the ability to move large volumes of goods in one trip, the cost per unit of cargo is reduced. This is particularly important for bulky and heavy goods, where transporting them via other methods is significantly more expensive. Many large companies prefer maritime transport for their massive shipments to reduce overall costs.
High Capacity
Maritime transport is especially effective due to its high capacity and ability to carry large quantities of goods in one trip. Large cargo ships can carry hundreds of thousands of tons of goods, which is extremely beneficial for international trade and the transportation of raw materials, industrial products, machinery, and consumer goods. Container ships, which follow specific standards for cargo handling, allow the transportation of thousands of containers in a single voyage, significantly reducing costs and transit times.
Environmental Sustainability
Compared to other methods, such as air and road transport, maritime transport is more sustainable in terms of greenhouse gas emissions. This method produces fewer pollutants per ton-kilometer of cargo movement. This characteristic makes maritime transport a suitable option for reducing environmental impacts. As a result, many countries and companies are working to enhance the role of maritime transport in mitigating climate change by using newer ships and green technologies.
Higher Safety for Goods
Maritime transport generally provides greater safety for goods due to the use of sealed, standardized containers. Unlike road transport, where goods may be vulnerable to theft or damage, marine containers are securely sealed and protected inside large ships. Furthermore, maritime accidents occur less frequently than road or air accidents, which contributes to the increased safety of maritime transportation.
Suitable for Moving Heavy and Bulky Goods
Many heavy and bulky goods, such as minerals, crude oil, liquefied gas, and heavy machinery, are transported via sea. Due to the high capacity of ships, these types of goods, which may be impossible or prohibitively expensive to transport by other methods, are easily and more cost-effectively moved by sea.
Disadvantages of Maritime Transport
Despite its many advantages, maritime transport also has several disadvantages. These include slower speeds compared to air and road transport, reliance on weather conditions such as storms and fluctuations in climate, and limited access to non-coastal areas. Additionally, the need for adequate infrastructure at ports and rivers can lead to additional costs for development and maintenance, creating limitations in certain regions.
Slow Speed
One of the major drawbacks of maritime transport is its slow speed. Due to the large volume and weight of the cargo they carry, ships naturally require more time to cover long distances. In comparison to the fast-paced air transport, cargo ships may take weeks or even months to move goods from one country to another. This slow pace can be problematic for businesses that require fast delivery.
Dependence on Weather Conditions
Maritime transport is heavily affected by weather conditions. Storms, high waves, and unfavorable weather can easily disrupt maritime shipping schedules. Long delays or even damage to ships and cargo are common issues arising from adverse weather conditions. This dependency on weather makes precise scheduling for maritime transport difficult.
High Additional Costs
Although the initial costs of maritime transport are relatively low, there are many additional expenses such as loading and unloading cargo at ports, port fees, insurance costs, and ship maintenance that can significantly impact the overall cost of transportation. Moreover, congestion at ports and delays caused by it can further increase costs. These challenges can significantly raise the transportation expenses.
Limited Access to Inland Areas
Another disadvantage of maritime transport is the inability to directly access inland and remote areas. Water transport is only feasible along water routes like seas and rivers, meaning it cannot reach landlocked areas. As a result, to deliver goods to inland or remote locations, it becomes necessary to use land or air transport, which increases both time and cost.
Piracy and Security Issues
Piracy is a significant challenge in international maritime transport. Especially in regions like the waters off Somalia or the Gulf of Aden, pirates pose serious threats to ships. These threats lead to higher insurance costs, the need for additional security personnel, and ultimately an increase in transportation costs. In addition to piracy, security concerns such as theft or damage to goods can also create further problems for cargo owners.
