Largest Ship Propellers In The World

Largest Ship Propellers In The World

Humans are always fascinated by the biggest and the fastest. Ships which are some of the most mammoth structures made by us provide us plenty of opportunities to be awed. Have you wondered how these giants on the sea move? Propeller is the answer. And to move the biggest ships in the world, we need the largest ship propellers in the world!

Propellers are generally used to make an object move forward. The thrust produced by the rotation of propellers drives the ships or aircrafts.  Propellers are used in aircrafts and ships. In our childhood, we all have played with small boats having a small fan-like structure on the back and on rotating that fan our boat would move in the water. Now imagine, for making a huge ship move forward we need a huge propeller.

It measures a whopping 395 meters long, 59 meters wide with a draught of 16 meters which is equal to the size of four combined football fields. Obviously, such a massive ship needs the biggest propeller.

2) EMMA MAERSK

Before the manufacturing of Triple-E-Class ships, Emma Maersk was the biggest ship in the world. Being one of the oldest and largest ship containers (1302 feet long and 207 feet wide), Emma Maersk has one of the world’s largest ship propellers. This propeller, having a diameter of 9.6 meters and weighing 130 tons, is owned by A. P. Moller-Maersk Group. It is a six-blade propeller made of an alloy of copper, aluminum, nickel, iron, and manganese.

Icebreaker, Nathaniel B. Palmer, is a ship made for the navigation through the ice-covered water and is mainly used for the research purposes. For making a ship to move through the ice-covered water propeller with high strength are needed. Therefore, the propellers of this ship are made up of a sturdy alloy.

This ship has two four-bladed propellers that are about 4 meters long.

12) ELATION
