Probe controlled Degaussing system

Principle : Under Normal operating conditions the degaussing system is automatically controlled. However, if required, it may also be manually controlled by accepting a few restrictions. The external field changes acting on a ...

Operation of Impressed current cathodic protection

Earlier, We had discussed about the theory behind the use of Impressed current cathodic protection. To refer the aforesaid post, visit http://electricalfundablog.com/blog/?p=731 . Lets discuss how the operation ...

Theory behind Impressed current cathodic protection

Impressed current cathodic protection is a method for ship’s hull protection. But, before discussing the Impressed current cathodic protection, its important to know the theory and history of cathodic protection. Cathodic Protection is a method ...

Sacrificial Anodes

In this type of system, the ship’s hull is forced to become a cathode with respect to electrodes that are positive with respect to the ship’s hull. The electrodes used for this purpose are Zinc, Magnesium ...

Hull protection methods

Paints alone cannot accord complete protection to underwater hull. Areas above keel blocks are not always possible to protect by painting. Stern areas suffer erosion due to high turbulence caused by propeller. In these areas, chances ...

Importance of Hull protection

If we go back in history, we can understand that the man has involved himself with works and resources of sea from a long time. He has been continuously improving and producing structures for using it ...
