What is a Tanker Ship?

This is a type of a ship which has the capacity to carry million tons(mt) of liquids.There are special holds in the tankers which assist in preservation of the liquid.
These liquids are classified as
01.Crude Oil Carriers.
02.Chemical Carriers.
03.Product Carriers.
04.Gas Carriers.
05.Combination Carriers.

These liquids are also measured in DWT(Dead Weight Tonnage).

Out of these, the mostly traded form of liquid is Crude Oil followed by Chemical.

The largest Crude Oil Carrier is over 500,000 DWT.For a crude carrier, the vessel must be fitted with a Crude Oil Washing (COW) and an Inert Gas System (IGS).

Chemical Carriers are also known as Product Tankers.There are as many as 1000 chemicals traded by sea today.
Chemical Tankers can carry approximately 90 mt of bulk liquid products.

Product Carriers can be clean or dirty depending upon the trade between shippers and merchants.

Gas Carriers are of 2 types.They are LNG and LPG.
LNG is a clean fuel,regarded as a special cargo which cannot be compared to any other form of shipping.
LPG is a primarily used domestically as a means of cooking food and in Industrial houses for heating purposes.

Combination Carriers.
These are the formation of two products of liquids traded together for better benefits.They are kept in separate holds of the ship.
