Greatest volume of cargo in international trade is carried by sea transportation. This explains one of the important roles sea transportation plays in the world. Freight transportation by sea is a cheaper means by which people move their cargoes in large quantity from one nation to another. Industrial revolution becomes effective in a nation that has a well-developed marine transport. Indeed,
it’s a necessary complement to other modes of freight transportation and trading
activities.
However, ships can be classified by its propulsion and size. Below are the types of
ships in marine transportation:
1. Bulk Carriers: Like the name suggests, they are cargo ships used to carry large number of cargo. The main surface of the out-side floor of the ship is designed like a large box to carry cargoes.
2. Container Ships: Like the name suggests, it is used to carry large dry cargoes packaged into large standardized containers. To a large extent, most of these ships are moved by diesel engines.
3. Tankers: They are designed to carry liquid materials such as petroleum gas, crude oil, petroleum products, liquefied petroleum gas (LPG), liquefied natural gas (LNG), chemicals, vegetable oil, wine and so on.
4. Refrigerated Ships: These are also cargo ships used to carry perishable items that need controlled temperature to preserve its freshness and such perishable items include: fruits, meat, fish, and vegetable among others.
5. Roll-on/roll- off ships: These ships are specially designed to carry dry cargoes like automobiles, trailers, railway carriages. The ships are designed with ramps that make it easy to roll in and roll out.
6. Coastal Trading Vessels: These are used for trading activities between different areas, nations and continents. They are usually small in size.
7. Ferries: These kinds of vessels are commonly used as public transport for people living in water-side areas; they are used to move passengers and their belongings such as any form of vehicles, luggage, and equipment, among others.
8. Cruise Ships: These are used mostly by tourism industries. They are ships used purposely for pleasure and people traveling in cruise ships are people traveling for recreation.
9. Ocean Liners: These are ships used to carry large number of people from one seaport to another on a long regular- distance planned at a certain time. They are also used to carry cargoes, mails and at times, they are used for any other purpose. Ocean liners normally are strong ships designed to resist rigorous conditions they are likely to face while on ocean.
10. Cable Layers: These are undersea or submarine built vessels purposely used to lay cables for telecommunications, electricity etc. below the surface of water.
11. Tug-boats: These boats are used to tow other boats or vessels.
12. Dredgers: They are ships usually used in a depth-less area of the sea that may affect smooth operations of the ship. These ships are designed to dig out and remove the materials that sink to the bottom of the sea.
13. Barges: They are flat-bottom boats usually used to move heavy cargoes on rivers and canals. It is important to note that most barges use tugboats or towboats to operate.
14. Multi-purpose ships: They are ships used to carry various items both in bulk and small quantities and at times, they are used to move heavy items. The modern ones are now designed to carry containers.












A truck or lorry is a motor vehicle specially made to move goods from one place to another. Trucks differ in size, power and structure. There are smaller trucks and very powerful large trucks made purposely for commercial purposes to carry specific equipment like fire trucks, concrete mixers trucks, garbage trucks, etc.
List of Truck Classification by size
a. Ultra Light Truck
b. Very Light Truck
c. Light Truck
d. Medium Truck
e. Heavy Truck
f. Off Road Trucks
Trucks can also be classified according to the specific function of the body they carry.
1. Refrigerator truck: It is a truck with a device that is used to move fresh goods from one place to another. Such goods are frozen items which include: ice cream, food, and vegetables, among others.
2. Box truck: This is a cargo box-like container of a vehicle that is designed to carry goods. It’s often designed or structured in an enclosed box-shape with a door fitted at the back or the side of the truck purposely to load and to off-load cargo.
3. Concrete mixer: It is a truck with a container or body for mixing concrete by rotating in one direction in such a way that all particles therein follow the turning circle at a center point with a common velocity.
4. Dump truck: This is also known as a tipper in some English speaking countries. A dump truck is a truck with an open-box container at its back to carry loose materials like sand, gravel etc. It is also designed with elevation in front of the container to lift it up to a higher position to enable off-loading the contents through the rear fitted door.
5. Flatbed truck: This is a trailer having a flat surface to carry objects or cargo. It is the best vehicle in road transportation to carry both long and short containers from both seaport and railway stations to a desired location.
6. Semi-truck: This is a truck with a long trailer attached to the back of it.
7. Tank truck: This is also known as a tanker truck. It is designed to carry liquid materials such as: water, kerosene, petrol, diesel, among others. Some tank trucks are specially designed to carry gasses and any other hazardous and inflammable materials.
8. Tow truck: This is a truck used to tow away other vehicles that suddenly break down on the road probably due to a serious accident or a mechanical fault. Such trucks are designed with special equipment on its back to tow away stuck vehicles on our public roads.
9. Specialized heavy truck: This is also known as a heavy duty truck designed to be used for very difficult and intensive tasks such as carrying oversized equipment or objects.
10. Off-road heavy truck: This is also a very large truck designed specially to be operated away from the public roads.
