VESSELS TYPE AND SIZE


2/17

SHIPS

A ship is a large vessel that floats on water

Generally distinguished from boats based on size and

cargo or passenger capacity.


3/17

SIZE OF SHIPS

DWT : Deadweight Tonnage

The carrying capacity of the ship, namely the total weight ofcargo, fuel, fresh water etc.

GRT : Gross Registered Tonnage

Total volume of the ship (in m3) divided by 2.83 m3

NPT : Net Registered Tonnage

Available volume of cargo, i.e. GRT the volume of engine

room, compartments for operation and ballast tanks

DT : Displacement TonnageThe total weight of the ship, i.e. the weight of the sea water

displaced by the ship

TYPES OF VESSELS

Ocean going vessels are classified by the type of cargo they

carry and their size expressed as DWT. In some cases, a

vessel is classified by its length and width.

Bulk Carriers

These vessels carry dry (grains, fertilizers,

phosphates and ores) or wet (chemicals, orange juice,refined petroleum products) bulk cargo.


5/17

Handysize

Size: 10,000 - 30,000 DWT

These are small bulk carriers that make up the majority of the

world's short haul fleet. Handysize can refer either to a bulk

carrier or tanker.

Handymax

Size: 30,001 - 50,000 DWT

These are a larger version of the Handysize vessels and popular

for both bulk and crude carriers. These vessels have a large

variation in size and characteristics.


6/17

Panamax

Size: 50,001 DWT - 80,000 DWT

This is the maximum size ship that can pass through the locks ofthe Panama Canal. Locks are 1000ft long by 110ft wide and 85ft

deep. Panamax dimensions are: overall length (LOA) of 965ft

(290m); beam of 106ft (32.3m); draft of 39.5ft (12.04m).

CapesizeSize: 80,001 DWT - 199,000 DWT

These are vessels that are too large to pass through the locks of

either the Panama or Suez Canals. As a result, these vessels must

travel around the Cape of Good Hope in South Africa or CapeHorn in South America to their destinations. These vessels also

require deep-water ports.


7/17

Very Large Ore Carriers (VL Ore Carriers)

Size: 200,000 DWT

These vessels are the largest bulk carriers and also cannot passthrough either the Panama or Suez canals.

Tankers

These vessels carry refined petroleum products in numerous bulk

tanks for safety and in order to carry a number of differentproducts in a single voyage.

Tankers of less than 100,000 DWT are referred to as either

"clean" or "dirty". Clean tankers carry refined petroleum products

such as gasoline, kerosene, jet fuels, or chemicals. The so-calleddirty vessels transport products such as heavy fuel oils or crude

oil. Larger tankers usually only carry crude oil.


8/17

Coastal

Size: 3,001 DWT - 10,000 DWT

These are the smallest tankers and are generally used in coastal

waters requiring a shallow draft. Coastal tankers typically carry

kerosene, heating oils, fuels and chemicals.

Small

Size: 10,001 DWT - 19,000 DWT

This is the next size up tanker and is still often used in coastalwaters. These also typically carry kerosene, heating oils, fuels and

chemicals.

Handy or Handysize

Size:19,001 DWT-25,000 DWT; Alternate: 10,000 - 34,999 DWTThis is a popular-sized tanker, but typically not used in very long

voyages
