The tanker has so much load, is it driven by a propeller?
Most oil tankers are driven by only one propeller. Why are oil tankers that are obviously bigger than an aircraft carrier, yet they are driven by only one propeller? We must know that many oil tankers can almost catch up with the aircraft carrier's draft, but there is still only one propeller tanker with so many loads. Why is there only one propeller? Does it drive you?
First of all, since the birth of the aircraft carrier, high speed has been its essential attribute. Because of the mission required, the aircraft carrier needs to quickly move to various places on the ocean, and a high speed of 25 knots can provide a "deck wind" that is conducive to take off and land for the carrier aircraft.
But oil tankers don’t need it. Although speed represents higher efficiency, we all know that the advantage of ocean shipping is definitely not speed. Carrying so many tens of thousands of tons or even hundreds of thousands of tons of things and running so fast, the little time and efficiency saved can not keep up with the gas money. Saving the space and oil storage capacity of an engine and axle system can optimize the tanker's transportation layout and load more things.
Although it seems that the propellers under the tanker are only a little smaller, you will know that there is nothing small when you get closer. Depending on the size of the hull, the propellers vary from one to ten meters, and most floors are only three meters high. Secondly, after the tanker enters the ocean, it will quickly look for ocean currents to drive itself, but the speed is not slow. With the birth of technologies such as temperature control and sealing, sea transportation has become the main means of transportation in today's world logistics.
Naturally, technology is constantly improving.
