Cargo ship

Types of cargo ships2

Cargo ships are constructed to carry different types of goods across the oceans. They are the primary vessels used in maritime trade, transporting over 80% of the world's goods. Several types of cargo ships exist, each tailored to transport specific types of cargo. Here are some of the most common types:

• Container Ships: Container ships are designed to carry containerized cargo. The containers are securely fastened to the deck with twist locks and lashed with steel cables. Container ships have revolutionized global trade, allowing for efficient and flexible transport of goods. They come in various sizes, from Panamax ships that fit the Panama Canal to the massive New Panamax and Maersk Triple E-class vessels. Container ships are characterized by their large, boxy superstructure and extensive hatch covers.
• Bulk Carriers: Bulk carriers transport unpackaged bulk cargo, such as grains, coal, iron ore, and other raw materials. They have large, spacious holds for easy loading and unloading with cranes or conveyor belts. Bulk carriers are typically smaller than container ships but can be exceptionally large, with a deadweight tonnage (DWT) exceeding 500,000 tons. They are distinguished by their large cargo holds and absence of hatches.
• Tankers: Tankers are cargo ships designed to transport liquids, including crude oil, refined petroleum products, chemicals, and liquefied natural gas (LNG). Oil tankers carry crude oil from extraction sites to refineries. Chemical tankers transport various chemicals, often requiring specialized equipment and safety measures. LNG carriers are equipped with insulated tanks to transport liquefied natural gas at cryogenic temperatures. Tankers vary in size from small coastal tankers to massive VLCCs (Very Large Crude Oil Carriers) and LNG carriers. They are identified by their large tanks and absence of hatches.
• Roll-on/Roll-off Ships (Ro-Ro): Ro-Ro ships are cargo ships designed to carry wheeled cargo that can be driven directly onto the vessel and off again using ramps. This type of cargo includes cars, trucks, construction equipment, and other vehicles. Ro-Ro ships have internal or external ramps that allow vehicles to roll on and off the ship. They are characterized by their large, sloping stern and wide cargo decks.
• General Cargo Ships: General cargo ships are versatile vessels that can carry various goods, including breakbulk cargo, project cargo, and palletized goods. They are equipped with cranes and other handling equipment to load and unload different types of cargo. General cargo ships are smaller than container ships and bulk carriers and have multiple cargo holds and hatches.

How to choose cargo ships

To choose the right cargo ships for sale, business owners need to consider the following factors:

• Cargo capacity

  It is essential to choose a cargo ship with the right cargo capacity depending on the customer's target market. Business owners should understand that different types of cargo ships have distinct cargo capacities. For instance, container ships vary in sizes from small feeder vessels with a capacity of about 2,000 TEU to large post-Panamax vessels with over 20,000 TEU. Similarly, bulk carriers range from small coastal bulk carriers with a capacity of about 5,000 DWT to large Cape-sized bulk carriers with over 150,000 DWT. Therefore, business owners should have a clear picture of the cargo ship capacity needed to serve their customers' interests.

• Cargo type

  Business owners should also consider the type of cargo their potential customers will be transporting. As seen above, various types of cargo ships are built to transport distinct types of cargo. For example, liquid cargo ships are constructed to carry liquid cargo, such as chemicals, oil, and gas. Similarly, refrigerated cargo ships have temperature-controlled containers for transporting perishable goods. Therefore, business owners should be aware of the requirements for the different types of cargo to ensure they get the right cargo ships.

• Operating costs

  Business owners must consider the operating costs of the cargo ship. They include the fuel efficiency, crew costs, maintenance expenses, and insurance. Selecting a cargo ship with lower operating costs is crucial to ensuring higher profits. At the same time, business owners should be careful not to compromise the ship's quality and performance.

• Ship age and condition

  The age and condition of the cargo ship are also important factors to consider. Older cargo ships are often less expensive but may require more maintenance and have higher operating costs. Newer cargo ships are typically more expensive but offer better fuel efficiency and lower maintenance costs. Business owners should therefore evaluate the ship's maintenance history, inspection records, and any recent repairs to determine its condition.
