1 Basic Knowledge Of Tankers

This course is meant for officers and ratings assigned basic duties and responsibilities related to cargo or cargo equipment on board oil and chemical tankers. By successfully completing this course, therefore mentioned  shipboard personnel will fulfill the mandatory minimum requirements of Regulation V/1-1 of STCW 1978, as amended.





Classification of Tankers on the basis of Type


  1. Oil Tankers: Oil tankers, as their name suggests carry oil and it’s by products. Oil tanker however, is a generic terminology and includes not only crude oil but also petrol, gasoline, kerosene and paraffin. Oil tankers are further sub-divided into two main types: product tankers and crude tankers:
  • Product tankers are used to transport the above mentioned petroleum based chemicals
  • Crude tankers are specifically used to transport crude oil from the excavation site to the crude oil refining industrial plant
  1. LNG Carrier: The LNG Carriers are those tanker ships that are used to cargo LNG or Liquefied Natural Gas. These types of tankers require careful and delicate handling owing to the precariousness of the material they carry. Statistically speaking, there are around 193 LNG tankers that are currently under operation.


Chemical Tankers: Chemical tankers are those cargo tankers which transport chemicals in various forms. Chemical tankers are specifically designed in order to maintain the consistency of the chemicals they carry aboard them. These tanker ships are applied with coatings of certain substances that help in the easy identification of the chemicals that need to  be transported

  1. Slurry Tankers: Slurry refers to all those materials that do not disperse or dissolve in  water  –  otherwise  regarded  as  waste  materials.  Slurry  is  used  as a fertiliser and  the  slurry  tankers  help  to  haul  slurry  to  areas  where  they can be put to productive use.
  2. Hydrogen Tankers: As the name suggests, hydrogen tankers are cargo tankers used for the shipping and transportation of liquefied hydrogen gas.
  3. Juice Tankers: Juice tankers or more specifically orange juice tankers which are used for the cargo carrying of orange  juice  in  mass  quantities. One of the biggest juice tankers is the Brazilian tanker Carlos Fischer. However, other fruit juices carriers are also available.
