Batteries are one of the energy sources available onboard vessels which are used in case of blackout and emergency situations on board a ship.

Energy efficiency is of sheer importance in all aspects of shipping operations today. The electrical system being one of the most important aspects on board must be included in the ship’s energy efficiency plans. Learn ten ways to achieve energy efficiency in ship’s electrical system.

This is the second article of the series A Guide to Welding Electrodes on Ships. Learn about the different types electrode nomenclature and classification in this article. This is a must-read guide for all mariners.

Navigation lights of the ships still play an important role in ship navigating procedures at sea. These lights require periodic maintenance to ensure smooth functioning. Find out the basics of navigation lights maintenance on ships.

Electrical ratings of transformer and alternator on ships are always done in kVA. Find out why they are mentioned in only KVA and not in KW, by understanding the concept behind the electrical systems working on ship.

A Ship cannot run on the traditional electrical systems with less voltage. The high capacity marine diesel engines and other machinery on ships require higher voltage systems to produce more electrical power. Find out the reasons for using high voltage systems on board ships.

Alternate marine power or cold ironing is a method of providing power to the ship from an external source. AMP is getting recognition around the world because of the rise in marine pollution.

Earth fault is considered very critical on board a ship. Some ships which operate at 440 V do not have any trip devices attached for a single earth fault. However when the operating voltage exceeds 3000V, it is mandatory to have a protection system which isolates when a machinery suffers an earth fault.
