Different Types of Ships and Vessels: Complete Guide 2023

The marine sector is intriguing, intricate, and dynamic. To remain competitive, shippers must have a solid understanding of the many vessel types that traverse the oceans of the world, as well as their comparative advantages and disadvantages. What kind of vessel to select for a shipper’s cargo is one of the most crucial considerations they must make. This decision will be influenced by a number of factors, including the type and weight of the cargo, the location, and the deadline. Commercial ships of all shapes and sizes travel the oceans of the world carrying a wide range of cargo. The article will examine how cargo vessels are divided and the types of ships and vessels. Shippers consider the pros and weaknesses of each type of vessel before making their choice.

Here are each vessel and kind in more detail

1. Dry Cargo Ships: 

Dry Cargo Ships

Dry cargo ships, also known as general cargo ships, were previously widely used by merchant fleets all over the world. These ships frequently had derricks, which are used to raise and load goods onto the ship.

Different sorts of cargo were kept in the holds (ship compartments), and the speed at which they could be loaded or emptied depended on two things:

  1. The crew members’ qualifications for duty on the ship.
  2. Port personnel are also referred to as “stevedores.”

While some dry cargo ships follow predetermined routes between particular ports, others evolved into what is now known as “tramp traders,” essentially travelling wherever they were needed at any given moment.

Types of Dry Cargo Ships
1.) Bulk Carriers

These are different types of ships built to transport enormous quantities of dry, unpackaged cargo like grains, coal, ore, and cement. These are typically large ships having a carrying capacity of 100,000 tonnes or above.

Bulk carriers’ key benefit is their ability to transport very huge loads, which is perfect for shippers who have a lot of cargo. Bulk carriers can be more challenging to load and unload than other types of vessels since they are less adaptable.

2.) Container Ships

These are ships built to transport a lot of containers, which are used to convey anything from electronics to clothing. These are typically very large ships with a capacity of roughly 20,000 TEUs (twenty-foot equivalent units). 

Container ships’ key benefit is that they are incredibly adaptable and can transport a variety of various sorts of cargo. Furthermore, loading and unloading them is not too difficult. However, when it comes to moving heavy loads of goods, container ships are less effective than other kinds of ships.

3.) General Cargo Ships

These types of ships go by the name Breakbulk as well, but they don’t use the same containers or have the same utilisation standards. Specialised handling facilities are frequently not required because they are normally put into pallets or bags. Loading Cranes, straps for boxes, or slings for bags can be used for unloading. These ships can also transport erratic and loose cargo. In similar circumstances, the crew of the ship packs the cargo to reduce damage and maximise space.

4.) Reefer vessels:

These types of vessels are made to transport perishable items like food that must be kept at a specific temperature, such as refrigerated goods. They are mainly lesser in size than container ships, with a range of around 5000 TEU.

5.) Ro-Ro Vessels:

They are made to transport vehicles and trailers that have wheels. Normally, they can hold up to 2000 automobiles.

2. Liquid Cargo Ships:

Liquid Cargo Ships

These are the containers used to transport liquids in big tanks. In the middle of the 1800s, iron was used to build the first tanker ship because it was both inexpensive and robust enough to retain liquid without leaking. Size has to grow with time due to economies of scale, and some tankers can contain more than 400000 tonnes of liquid.

Types Of Ships and Vessels of Liquid Cargo Ships
1.) Crude Carriers:

The Very Large Crude Carriers (VLCCs) and Ultra Large Crude Carriers (ULCCs) are among the largest ships currently at sea. These move oil from fields of production to refineries, where it is transformed into petroleum products. The typical large crude carrier often loads and unloads at an offshore buoy or terminal rather than a port because of its massive size. 

2.) Product Carriers:

The refined products are transported from major terminals to worldwide smaller ports by these types of ships, which are typically smaller than crude carriers. These tankers transport non-petroleum bulk liquids such as palm oil and molasses in addition to petroleum, diesel, jet fuel, asphalt, and lubricating oil.

3.) Chemical Carriers:

These ships typically have a deadweight capacity of 5000–4000 tonnes and have cargo holds with adjustable temperature controls. To ensure the preservation of purity for things held in these tanks, these systems additionally employ cutting-edge cleaning procedures.

4.) Liquefied Gas Carriers:

These oil tankers have undergone significant changes and now have the very particular function of transporting either liquefied petroleum gas or liquefied natural gas under pressure. The design of the cargo tanks is typically spherical since it makes them stronger.

3. Specialised Cargo Ships:

Specialised Cargo Ships

It is a different type of ship from others as since many commodities are highly specialised, particular loading, unloading, and stowage arrangements are needed. The term “specialised” takes on a new meaning when certain cargo categories are transported with such frequency and convenience.

Types of Specialized Cargos
1.) Passenger’s ships:

Transport trucks falling under this category range in capacity from ten to 6,000. Both foot ferries and cruise ships fit the criterion; the latter is motivated by passenger preferences.

2.) Livestock Carriers:

Large cargo ships called “livestock carriers” have pens on them that can hold a lot of animals. Ample water, food, appropriate ventilation, and space are the major concerns when transporting livestock. Animal handling facilities must be available in the places that receive these vessels.

3.) Heavy Lift or project cargo ships:

These ships were frequently built specifically for the transportation of very huge objects, such as entire ships and sizable industrial components. They can be used, for instance, to transport an offshore platform from its building site to the place of drilling.

4.) Tugs:

Even though manoeuvrable types of ships are now available, tugs are still vital to the maritime sector. Modern tugs are extremely manoeuvrable and have pulling capacities that exceed 100 tonnes. Ports around the world frequently see harbour tugs, which normally have less power than other types of tugs.
