What Is The Shaft Grounding System :- lmstull


The professors at the top marine colleges in India suggest consulting a professional to know more about the current information of the grounding system and how to install the same. Ground shafting is an important consideration for all marine vessels.

Marine Engineering usually witnesses the concept of shaft grounding systems in all its cargos and other carriage items. Installation of shaft grounding systems is considered to be very important in terms of all the marine equipment.

Why is the Shaft Grounding System an Important Part of Marine Engineering?

Basically, the purpose of installing shaft grounding systems in marine engineering is very scientifically driven. According to the experts and researchers of the top marine engineering colleges in India, installation of shaft grounding systems in marine engineering means the electricity and water don’t get mixed. This avoids all kinds of mishaps otherwise witnessed by an individual. Moreover, if the seawater gets mixed with the electrical system of a propeller, this could lead to corrosion, loss of efficiency as well as system failure.

In order to protect a ship from all kinds of technical and mechanical perils or mishaps, it is very important to ground the propeller of the ship to the hull electrically. Such kind of grounding helps restrict and avoid corrosion as well as damage that might otherwise be caused to the shaft, gearbox, and bearings of the propeller. IMU CET has recommended that every motor-powered marine vessel should entertain some shaft grounding system installed to ensure a smooth and free-flowing marine operation.

The mechanism of shaft

The experts at the top marine colleges in India claim that shaft is known to be one of the most critical parts of the propulsion system of the marine vessel. These shafts could easily become corroded over a certain period of time, after losing their efficiency. Such overly corroded shaft could lead to the overall failure of the system. This is where the grounding system comes to an escape.

The shaft also helps to provide thrust to enable the movement of the vessel. These shafts become corroded over a period of time because of certain electrochemical reactions with water. Such a reaction makes these shafts weaker in terms of transferring energy from the engine of the vessel to its exterior propulsion system.

A grounding system is also considered to be necessary to protect the drive-motors bearing from facing any kind of electrical damage. Excessive capacitive discharge could lead to heavy electrical bearing failure.

Working of the shaft grounding system

According to IMU CET, the principles behind the shaft grounding system is very easy. In the most number of marine vessels, the propellers driven by electric current create charges along with the exposed sections of the prop. A grounding system helps to ensure that the smaller the charge, the more possible it becomes to escape. This overall system is designed to ground out all the electricity into the hull of the ship.

Different types of grounding may be required for different vessels

There are different types of grounding the installation of which varies from one vessel to the other. The owners can select from a range of choices while making a choice of the grounding system for their vessel. The factors such as engine type, the overall size of the ship, composition of the hull, etc. are usually taken under consideration while choosing the type of grounding.
