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.

The popularity of 3 phase induction motors on board ships is because of their simple, robust construction, and high-reliability factor in the sea environment. A 3 phase induction motor can be used for different applications with various speed and load requirements.

For proper working of any 3 phase induction motor it must be connected to a 3 phase alternating current (ac) power supply of rated voltage and load. Once these three phase motors are started they will continue to run even if one of the three phase supply lines gets disconnected. The loss of current through one of these phase supply is described as single phasing.

For measuring several electrical parameters to analyze and keep machineries in proper running condition, a permanent magnet moving coil (PMMC) instrument is used onboard.

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.
