Maritime Shipping and Sea Transportation
Today, a significant portion of successful international trade is conducted via maritime shipping and related services. One of the most important factors in determining the mode of transportation is a country’s geographical conditions.
Maritime transportation is the world’s largest industry and employs approximately 2.5 million people. This industry has a substantial impact on countries’ foreign trade, to the extent that nearly ninety percent of global commercial transportation is conducted by sea.
Access to well-equipped cargo vessels is essential for maritime transportation. A considerable share of Iran’s maritime transport operations is carried out through the southern seas of the country.
Important Documents in International Maritime Transportation
Which Goods Can Be Transported by Sea
The following types of goods are suitable for sea transportation:
- Goods with a very large volume.
- Goods for which long transit times do not affect quality, noting that temperature-sensitive goods may be transported using refrigerated containers.
- Goods for which delayed delivery does not result in loss of market opportunity.
Means of Transportation in Maritime Shipping
The type of maritime transport vehicle is selected based on the distance between the loading point and destination, as well as the type and volume of goods. Common types include:
- Landing craft.
- Traditional vessels.
- Barges.
- Ships.
- Barges and similar marine vessels.
Advantages of Maritime Shipping and Sea Transportation
- Sea transportation is less costly than other modes of transportation.
- Due to the high volume of goods, operational efficiency in this method is relatively high.
- Freight rates are generally stable and are determined by major maritime transportation companies.
- The transportation of large-volume cargo is possible via maritime shipping.
Advantages of Maritime Transportation in Iran
Due to its geographical position, Iran enjoys several advantages in the field of maritime transportation, including the following:
- Access to major seas in both the northern and southern regions of the country.
- Extensive coastlines.
- Access to international waters through the Indian Ocean.
China, the United Arab Emirates, and South Korea are among the countries with the highest volume of maritime imports to Iran. Major imported goods transported by sea include:
- Medical equipment.
- Industrial raw materials.
- Road construction machinery.
- Sports equipment.
- Aircraft and vessel-related supplies.
- Club and recreational equipment.
- Food and consumable products.
- Various toys and textile machinery.
Disadvantages of Maritime Transportation
Compared to its advantages, the disadvantages of maritime shipping are limited. The primary drawback of this industry is the lengthy transit time. For this reason, maritime transportation is unsuitable for goods that degrade over time or for markets requiring rapid delivery.
Types of Ships Based on Routes
- Liner vessels with regular routes that operate according to a fixed schedule.
- Tramp vessels with irregular routes that do not follow predetermined shipping lines and transport cargo based on demand.
Methods of Maritime Cargo Shipment
Direct Shipping
In this method, the vessel proceeds directly to the destination without any stops, resulting in shorter delivery times.
Indirect Shipping
- Cross-stuffing: An indirect method in which cargo is transferred from one vessel to another before reaching its final destination.
- Chartering: This method is used for transporting large volumes or unpackaged goods. Vessels are chartered exclusively for cargo transportation. Charter contracts are not accepted by banks.
- Transshipment: This method is used when customs clearance is not permitted at the intended port, requiring the cargo to be transferred to another customs office.
- Groupage transportation: also known as consolidated shipping, is used when cargo volume is less than a full container load. The cargo is transported jointly with other shipments and delivered separately at the destination.
- Bulk transportation: In this method, goods are loaded onto the vessel without packaging or containerization.
Frequently Asked Questions About Maritime Shipping and Sea Transportation
High volume goods, goods not affected by long transit times, and goods with low time sensitivity are most commonly transported by sea. Temperature-controlled goods may also be transported in refrigerated containers.
Lower costs compared to other transportation methods, the ability to transport large volume goods, operational efficiency for bulk cargo, and stable freight rates are among the main advantages.
The primary disadvantage is the long transit time, which makes it unsuitable for perishable or time-sensitive goods.
The two main types are liner vessels with regular routes and tramp vessels with irregular routes.
Methods include direct shipping, indirect shipping, cross stuffing, chartering, transshipment, groupage transportation, and bulk transportation. Each method is selected based on the nature of the cargo and destination.
