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 ...

Degaussing coils

The potency of a magnetic field is measured in terms of Gauss. And therefore, by definition,  degausse means to reduce/eliminate the strength of the magnetic field. Degaussing coils are used to reduce the effect of ...

Ship’s induced magnetism

The magnetic field induced in the floating structure is dependent on the potency of the Earth’s magnetic field and the layout and direction of floating structure w.r.t. the Earth’s magnetic field. As discussed earlier, The ship’s induced ...

Ship’s permanent magnetic field

The Earth’s magnetic field is the cause of the ship’s permanent magnetic field. The process of constructing a ship in the Earth’s magnetic field generates an appreciable amount of permanent-magnetism in the floating metal structure. ...

Earth’s Magnetic field

We all know that the Earth has its own magnetic field. And it is due to its composition and moreover due to its core. Our Earth’s core is composed of enormously heated metals in ...

Degaussing

The potency of a magnetic field is measured in terms of Gauss. Accordingly, if we define Degaussing. We can say that degaussing means the procedure to diminish the potency of a magnetic field. ...

EMI coupling methods

EMI is the short form of Electromagnetic Interference. It is a generalization of an older terminology RFI (Radio Frequency Interference). Electromagnetic Interference can be defined as an electro-static/electro-magnetic disturbance which results in malfunctioning or undesired response in ...

Electromagnetic Interference

As the name clearly suggests, EMI stands for Electromagnetic Interference. It is a generalization of an older terminology RFI (Radio Frequency Interference). EMI can be defined as an electromagnetic or electro static disturbance that causes malfunctioning ...
