Types of Ships – Full List of 11 Different Types

1. Passenger Ships

different types of ships

First, on our list of different ship types are passenger ships. If a watercraft can carry over 12 passengers, it is already classified as a passenger ship. These vessels are strictly required to follow inland water and sea travel regulations. Strict compliance with these maritime laws is the response of governments worldwide to curb maritime disasters involving passenger ships.

Passenger ships have two general classifications: ferries and cruise ships.

  1. Ferry – This watercraft is used for transporting passengers on short distances. 
  2. Cruise Ship – This sea-going vessel is mainly used for leisurely travel. Most of these ships travel to selected tourist spots around the world. Cruise ships compete with each other by offering passengers high-quality entertainment, hotel-like accommodation, and a wide range of foods and drinks.

Cruise ships are further classified into several cruise ship types, and they are:

  • Cruise ships, liners, pilgrimage ships
  • Arctic and Antarctic cruises
  • Coastal ferries, harbor ferries, and channel ferries

2. Tanker Ships

Tanker ships are designed to transport vast quantities of liquid cargo. Most tankers carry oil, but some also carry chemicals, water, and even wine. These ships come in various sizes. Some can carry hundreds of thousands of tons of liquid.

Tanker ships are classified into several tanker ship types:

  • Oil Tankers – Ships that transport oil
  • Chemical and Product Carriers – Ships that transport liquid chemicals and other liquid products
  • Liquefied Gas Carriers – Ships that carry liquefied gas, such as LNG and LPG
  • Others – These are tankers that transport wines, juices, integrated tug barges, and other commodities

Tankers are also categorized according to their sizes:

  • Capesize
  • Suezmax
  • ULCC
  • VLCC
  • Handy
  • Lighters
  • Handymax
  • Aframax
  • Panamax

3. Container Ships

Third, on our list of ship types are container ships. Container ships are built to accommodate and transport huge amounts of cargo. These cargos are housed in metal containers that are arranged or compacted on the deck of the ship. Also, these ships can transport thousands of containers per trip.

Some container ships only have one deck, while others have multi decks. These ships play a crucial role in international trade as they transport all kinds of items, including machinery, metals, furniture, clothes, food, and many more.

Container ships are also further classified into the following sizes:

  • Suezmax
  • Panamax
  • Post-Suezmax
  • Post-Panamax
  • Post-Malaccamax 

4. Naval Ships

A ship designed for military service is called a naval ship. Naval ships are built differently from civilian ships, mainly because of their intended use. In general, these ships are armed with weapon systems. They are also made with stronger materials so that they can resist damage from outside forces

There are naval ships specifically made for naval warfare, and they are called warships. Ships made for support functions are called auxiliary ships. These ships are intended only for shipyard operations and seldomly used for troop and armament transport.

5. Special Purpose Ships

These ships are designed for special purposes. The different types of ships in this class include the following:

  • Ice Breaker Ships – These vessels are used to cut or break ice deposits in severe cold climate conditions so that water vessels can navigate through.
  • Research Vessels – These special ships can carry out various sea research. The most commonly known research ships are called polar ships, oceanographic ships, hydrographic ships, and seismic ships.
  • Salvage Vessels – These types of watercraft are designed to undertake salvage operations. Salvage vessels are mainly used to recover lost precious items at sea.
  • Tugs – These ships can move or maneuver other ships by towing or pushing them.
  • Barge Carriers – These ships have flat bottoms. They are primarily built for transporting heavy items in a canal or river.
  • Livestock Carriers – These water vessels are used to transport animals or livestock to the market.
  • Tenders – These large ships are designed as a support vessel to service other ships or boats. They are used to transport people and supplies to other ships or boats at sea.
  • Timber Carriers – These ships transport logs or timber.
  • Cable Layers – These vessels are used in laying cables on the sea bed. 
  • Lightships – These ships are used as lighthouses in the middle of the sea. They are stationed in deep-sea waters that are too deep for the construction of a conventional land-based lighthouse.
  • Pilot Crafts – These water vessels are designed to transport harbor pilots.

6. Bulk Carriers

different types of ships

Bulk carriers are large ships used in transporting cargo, mainly dry cargo, in huge quantities. These cargoes are generally loose and are not individually packaged. Such goods include coals, ores (metal), cement, food grains, and many more.

Bulk carriers are also classified into the following ship types:

  • Conventional bulker
  • Self-discharging bulker
  • Lakers
  • Gearless bulker
  • Geared bulker
  • BIBO

Maritime shipping has also designated some items as dry cargo, which can also be carried by bulk carriers. These bulk carriers are called:

  • Cargo Liners – These ocean liners are designed to carry passengers that are classified as dry cargo. For instance, a transatlantic voyage transporting passengers from America to Europe can be called a cargo liner.
  • Tramps – These ships do not use published ports of call and fixed schedules of the voyage.

7. Offshore Ships

Offshore ships are those used in oil exploration. They are also used to transport goods and people for construction projects at sea. There are different classifications for offshore vessels. The different types of ships in this category are:

  • Drill Ships – These ships are used in exploratory offshore drilling. Geologists and scientists aboard these ships are looking for new well deposits either for scientific drilling or for commercial purposes.
  • Semi-submersible Drill Rigs – These ships are mobile offshore drilling machines that build stable and sturdy platforms for oil and gas drilling operations. 
  • Diving Vessels – These are the class of ships used by divers as they accomplish their underwater jobs in the sea.
  • Supply Ship – These are ships that supply goods and materials to offshore rigs.
  • Floating Production Storage and Offloading (FPSO) – These vessels function as storage units. There are also offloading vessels used in the gas and oil industry that produce and process hydrocarbons, including oil storage.
  • Floating Storage Unit (FSU) – These vessels are used solely for storing oil and its by-products.
  • Accommodation Barges – These types of watercraft are used to accommodate people and cargo. They can also be used as stand-alone floating hotels.
  • Pipe Layers – These ships are used by pipe and cable workers to lay pipes and cables underwater.
  • Anchor Handling Vessels – These vessels are designed as service transport for employees of companies undertaking the building and installation of ocean-based projects.
  • Production Platforms – These ships are used in the extraction and processing of natural gas and oil. They can also be used as temporary storage units of oil and gas until they can be transported to shore for refining, processing, and marketing.
  • Crane Barges or Floating Cranes These ships are equipped with huge cranes designed to lift heavy loads.

8. Fishing Vessels

These vessels are averaged-sized ships that are primarily used for catching fish and other marine wildlife. Aside from commercial fishing, they can also be used for leisure cruising. Thousands of fishing vessels are being used to catch fish for personal or commercial purposes all over the world.

The International Maritime Organization (IMO) has a shocking statistic related to fishing vessels. It claimed that approximately 24,000 fishermen die on fishing vessels each year. It’s the reason why there is a requirement for all fishing vessels to install an ECDIS on their ships. The ECDIS can be used by fishing vessels to navigate through international waters safely and to avoid inclement weather.

There are two general classifications of fishing vessels. They are:

  1. Factory Ships – These ships function as fish processing vessels. They are big ships with all the necessary onboard facilities for the freezing and processing of all sizes of fish, including whales.
  2. Purse Seiners/Trawlers – Fishing trawlers, also called draggers, are commercial fishing vessels that can operate as pure trawlers. A fishing method that involves active pulling or dragging a trawl through the water is called trawling. In this operation, one or more trawlers will do the dragging of the net.

A purse seine is a big wall of netting that surrounds the entire school of fish. This seine is floated using small buoys attached to the perimeter of the net above the waterline and threaded through several rings running to the bottom of the net. When a school of fish is spotted on the water, a skiff or small boat encircles the area while it deploys the net.

9. Dredgers

When there is a need to excavate underwater soil, a dredger is usually the drafted sea craft to do the job. Dredging is usually done in shallow seawater to collect the sediments below or widen the water passageway.

Dredges have large excavation equipment that can remove sand and other sediments on the seabed. Some of the essential functions of dredgers are to undertake deep-sea mining and improve the navigational qualities of shallow coastal areas.

There are two general types of dredgers. They are:

  1. Hydraulic Dredgers – Hydraulic systems provide their excavation power. 
  2. Mechanical Dredgers – Their power of excavation comes from a mechanical gear system driven by powerful electric motors.

10. High-speed Crafts

Another on our list of ship types are high-speed crafts. You may think that ships can’t move on the water that fast. But these high-speed crafts are considered as a highly advanced and high-performance watercraft. While they are not widely used in commercial ships, they have successfully been tested and tried on small-scale traditional merchant ships.

There are five main classifications of high speed crafts. They are:

  1. Hydrofoil
  2. Small Waterplane Area, Twin-hull (SWATH)
  3. Wing-in-ground (WIG) Craft 
  4. Multihulls Including Wave Piercers
  5. Surface Effect Ship (SES) and Hovercraft

11. Ro-Ro Ships

Roll-on/roll-off vessels are well-known as Ro-Ro ships. They are mainly designed to transport wheeled cargo, such as cars and trucks. There are five different kinds of Ro-Ro vessels. They are:

  1. Full Ro-Ro Ships
  2. General Cargo + Ro-Ro Ship (GenRo) Ships
  3. Container Vessel + Ro-Ro (ConRo) Ship
  4. RoPax
  5. Pure Car Carrier (PCC) and Pure Car and Truck Carrier (PCTC) Ro-Ro Ships
