In order to fit with capacity the ever-growing size of vessels, there have been several reformation brought about in several navigation channels. Named such as Panamax, Handymax and Cape-size, there are significant developments as they highlight top of growth accomplished by the international maritime sector.

• Kamsar-max:

Maximum L.O.A 229 m refers to a new type of ships, larger than Panamax vessels, that are suitable for safely berth at the Port of Kamsar at “Republic of Guinea”, where the main loading terminal of Bauxite is limited to vessels not more than 229 meters.

Tanker Ships

specialized vessels for carry a massive amount of liquid cargo.
The main types of tankers are:
Oil Tankers: mainly carry crude oil and its products.
Liquefied Gas Carriers: a Gas carrier (or gas tanker) is a vessel designed to carry LPG / LNG or liquefied chemical gases in bulk.
Chemical & Product Carriers: is a type of tanker vessels designed to transport chemicals and different liquid products in bulk
On the basis of its size, tankers are further divided into various types such as:

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

• Roll-on Roll-Off Ships

• are used to transport any wheel cargo.
• Pure Car Carrier “PCC” and Pure Car and Truck Carrier {PCTC} Ro/Ro vessels
• Container Vessel + Ro-Ro (ConRo) Ship
• General Cargo +Ro/Ro vessels “GenRo” Ships
• RoPax
• Complete RoRo Ships

Offshore Vessels

mainly help in oil exploration and construction works at sea. Offshore vessels are of other types.
Some of the main ones are:
• Supply vessels: to supply for offshore rigs.
• Pipe Layers: Vessels involved in arrangement pipes and cables
• Crane Barges or floating cranes: is a ship with a crane specialized in carry heavy loads.
• Semi-submersible Drill Rigs: are Mobile Offshore Drilling Units to make stable platforms for drilling oil & gas
• Drill Ships: is a merchant vessel layout for use in explorative offshore drilling of new oil & gas wells / scientific drilling purposes.
• Accommodation Barges: a standalone floating hotel which can include accommodation as well as space for Cargo.
• Production Plat-forms: To extract and process oil & natural gas, or to temporarily store oil & natural gas until it can be brought to shore for refining and marketing
• Floating Storage Unit (FSU) mainly used for storage of oil and by products.
• Floating Production and Storage Unit {FPSO}I s a floating ship used by the offshore oil & gas industry for the production and treating of hydro-carbons and for the storage of oil & gas.
• Anchor handling vessels: hired for offshore construction & installation operation.
• Diving vessels Are used by divers for diving in the ocean for under-water works.

Specialty Vessels

are constructed and used for certain purposes.

Tugs:A tug (tugboat) is a boat or ship that maneuver vessels by pushing or towing them.

Tenders a boat / larger ships used to service / support other boats or vessels; by relocate people/supplies named by a tender vessel.
Pilot Crafts are used for transport of harbor pilots.
Cable Layers type of vessels help in laying cables on to the sea bed.
Research Vessels are special kind of ships used for carrying out a variant researchers at sea. most of these kinds of research vessels are seismic vessels, hydro-graphic vessels & oceanographic vessels and polar vessels, etc.
Salvage Vessels are engaged in salvage operation, recovery of lost property at sea.
Barge Carriers is a flat bottomed boat, built at most for river and canal transport of heavy commodity.
Timber Carriers: Vessels that carry timber
Livestock Carriers: Vessels that carry livestock/animals
Ice breaker vessels: They are used for cutting ice in extremely cold climate conditions to make waters navigation.


is an drilling activity usually carried out under-water at shallow seas or fresh water zone with the aim of gathering up bottom sediments and expanding.
are vessels with excavation tools used for removing sand and another types of sediment from the seabed.
used for several purposes such as making shallow coastal areas navigational & deep sea mining etc.
Dredgers are mainly classified into two types:
1. Mechanical dredgers
2. Hydraulic dredgers
