Accordingly, for bulk carriers, the ship size is oriented from 30,000 - 300,0000 DWT. Of which, coal import ships supplying thermal power plants, coal, ore for metallurgical complexes specializing in bulk cargo have a capacity of 100,000 - 300,000 DWT; Coal, ore, and alumina export ships have a capacity of 30,000 - 50,000 DWT.
For general cargo, the recommended ship size is a ship with a capacity of 5,000 - 50,000 DWT.
For container ships, ships running on the Asia route are oriented to have a capacity of 500 - 3,000 Teu and from 4,000 - 24,000 Teu for ships running on the Europe, Africa and America routes.
For liquid cargo, imported crude oil tankers have a capacity of 100,000 - 400,000 DWT. Imported oil product tankers have a capacity of 10,000 - 50,000 DWT, and imported petroleum tankers have a capacity of 10,000 - 50,000 DWT.
Liquefied petroleum gas (LPG) carriers have ship sizes ranging from 1,000 - 5,000 DWT and liquefied natural gas (LNG) carriers have a tonnage ranging from 50,000 - 150,000 DWT.
According to Giao thong Newspaper's research, the trend of increasing the size of container ships from 18,000 to 24,000 Teu is very clear. Data from the maritime magazine Alphaliner shows that by May 2020, there were 117 ships of this size, handling 2.36 million Teu, accounting for 10% of the world's total container volume.
The largest ship sizes are mainly in the young ship segment, with an age range of 0-4 years. Oil tankers have the largest average size, followed by bulk carriers and container ships. Ship sizes have increased rapidly in recent years to optimize costs and improve operational efficiency.
In recent times, the size of ships has tended to increase with the aim of saving operating costs, especially container ships.
In recent years, the world's cargo fleet has grown slowly, reaching only 2.71% - 4.13% in tonnage and 1.3 - 2.78% in quantity.
Although the number of ships has decreased, the size of ships tends to increase with the aim of saving operating costs, especially container ships with the generation of super ships of 23,000 - 24,000 Teu size being born.
The trend of increasing ship size is becoming more and more popular, especially on the Far East - Northern Europe and Far East - Mediterranean routes, with average ship sizes recorded from 12,000 to more than 15,000 TEU.
