Products tankers vary in capacity and therefore in size. Some are very small to enable them to enter small ports or to trade on inland waterways, canals and rivers; others are larger and carry oil products between ports that are further apart.
Products tankers carry all kinds of liquids :
- Petrol
- Diesel
- Aircraft fuel
- Bitumen
- Liquid Chemicals
- Vegetable Oils
- Fish Oil
Because of the type of cargo they carry, most products tankers have tanks that either are specially coasted, or are made of stainless steel.
