Oil tankers are now being targeted in the war between America, Israel and Iran. Everyone’s eyes are on the Strait of Hormuz. From where oil reaches many countries of the world. Many cargo ships of oil coming to India reach here through this route. Now the question is, how much oil do the cargo ships carrying oil and goods by sea consume every hour, and at what speed do they move?
Transport Geography report says, how much oil a containership consumes is determined by its size and speed. Now let us understand what is a cargo ship, its speed and the entire fund of oil.
How much oil does a ship consume every hour?
Let us understand this with an example. Suppose there is an 8,000 TEU container ship. Usually it is 300 meters long. How much oil will be required is determined by its speed. Its speed is measured in nautical miles per hour. For which knot is written. These ships usually move at a speed above 14 knots i.e. 26 kilometers per hour.
Suppose, a ship is moving at a speed of 24 knots i.e. 44 kilometers per hour, then 225 tons of bunker fuel will be consumed in a day. If we understand this on an hourly basis, the ship would require 9750 liters of oil every hour. Similarly, if it runs at a speed of 21 knots i.e. 39 kilometers per hour, it would require 150 tons of bunker oil in a day. This means that this ship will need 6,500 liters of oil every hour to run at its speed.
At what speed does oil get saved?
Shipping companies reduce fuel consumption by running ships at lower speeds, but doing so increases shipping time. Now let us understand at what speed ships travel.
- Normal Speed: It ranges from 37 to 46 km/hour. This speed is considered normal for a container ship and its engine to run. Most container ships are designed to travel at speeds of approximately 44 kilometers per hour.
- Slow Steaming: A speed of 33 to 37 kilometers per hour is considered slow. To save fuel consumption, the ship’s engines are run at less than their capacity, this increases the travel time, but saves fuel.
- Extra Slow: A speed of 27.8 to 33 kilometers per hour is considered extremely slow. This is also called super slow steaming or economical speed. Speed is reduced to minimize fuel consumption while maintaining professional service.
