Container ships are an important part of the cargo ships that are
widely used in international transportation. These vessels are designed to
carry containers or used for subsequent modifications.
Unlike other vessels, they are separated and classified by TEU
capacities according to the number of 20ft containers they can carry, not their
tonnage. However, the defined capacity is the maximum geometric capacity of the
ship. That is, all slots suitable for loading on the ship (the name given to
each TEU field) are mathematically specified.
The load capacity that the ship can carry actively is also indicated.
Container ships have double hulls with large hatches. Containers can be stored
on both deck and cargo hold. The containers loaded on the deck are connected to
each other by interlocks and are connected with the first three layers of steel
fasteners.
CLASSIFICATION OF CONTAINER AND SHIPS ACCORDING TO GENERATION
The classification according to the years refers to the periods in which
the ships were constructed and produced, rather than the date ranges in which
the ships were built.
1st generation container ships: 1956 - 1970, used in the length of
135-200m. carrying capacities max. The ships were around 800 teu and their
draft was less than 9m.
2nd generation container ships: Demand for container construction has
increased in parallel with the increasing interest in this sector and the
demand for the construction of ships serving this purpose has also increased
and sizes have been increased. These vessels were built between 1970 and 1980;
warehouses full cell guides (container cradle) used, capacity 1000-2500teus,
length 215m., drafts 10m. ships.
The 3rd generation container ships: vessels known as
"Panamax", built between 1980-1988, with a carrying capacity of
3000-5000teus, length 250- 290m. ranging from 11-12m. are the ships.
4. Generation container ships: "Post Panamax" are the
vessels; Constructed between 1988 and 1996, it has the capacity of carrying
4000-6000teus, with a length ranging from 275 - 305m. are the ships.
5th generation container ships: These ships, called "Post Panamax
Plus" (above Post Panamax), describe the ships built between 1996 and
2006. Their height is 335m. and above, carrying capacities 5000 - 8000teus,
drafts 13 - 15m. The vicinity.
6. Generation container ships: "Very Large" container ships
or "Suez max". These vessels are defined as ships built in 2006 and
later. Their height is 400m. carrying capacity 9000 - 15000 teus, drafts 16m.
The vicinity.
7th generation container ships: These vessels, which can be defined as
"Ultra large" or "Malacca max", are considered as future
container vessels and their carrying capacity is 18000t. 68m. , drafts of 21m.
accounts are made around.
This classification made by years should not be construed as the
construction of these ships only between those dates, but should be interpreted
as the starting and intensely demanding range.
CONTAINER SHIPS TONAGE MEASUREMENTS
GROSS TONNAGE (GRT) - GROSTON This is the volume measurement calculated
by dividing the value of all enclosed volumes of the ship in cubic feet by 100.
NET TONNAGE (NET) - NET TON This is a volume measure calculated by
dividing the money-saving volume of the ship by cubic feet.
DEADWEIGHT TONNAGE (DWT) - DEDVEYT TON It is the value of the weight
that sinks up to the summer loading line in the sea water with a density of
1,025.
DWT = Load + Fuel (DO, FO, LO) + Water + Storage + Passenger + Crew +
Paint + Ballast + Others
DISPLACEMENT TONNAGE (DISP) - DISPLACEMENT TONE The value of water in a
given state in tons of floating ships.
