Tug Boats are small but powerful ships which are used to pull or push other large ships for maneuvering or salvage purpose
We are familiar with the form of ship propeller, but have we ever contemplated upon their shape, appearance and typical geometry? Let’s find out inside the article.
A variety of factors are taken into consideration while selecting propeller for a ship. Learn about ten important points considered for efficient ship propeller design.
The efficiency of the propeller is pulled down by various losses such as vibration and noise. Learn about some of the important methods used by ship designers to reduce propeller vibrations and increase its efficiency.
To eliminate the usage of independently driven generators when the ship is sailing, a shaft generator is used. Shaft generator is a clean source of power, which does not burn any fuel to generate power.
Propeller is one such part of the ship which is fully visible only when the ship is out of water. Checkout ten amazing photos of ship propellers send by seafarers.
A propeller guard or a prop guard, as it is more commonly known, consists of a steel cage which surrounds the propeller. The prop guard freely allows the movement of the propeller and safeguards it against rough underwater parts.
The Sharrow Propeller increases efficiency 9-15 percent with same installation cost as traditional props.
NYK, MTI Co. Ltd., and JMU have successfully developed a highly efficient propeller by analyzing the conditions surrounding vessel propellers in actual operation.
