The selection of power system architecture for a ship primarily depends on the mission over the service life and the reliability desired. In discussing ship power system architectu... Read more
The first and foremost task for shipboard power system design is to compile a table of all connected ship electrical loads along with their load factors in all operating modes of t... Read more
Not all loads are turned on at all times, and many come one after another, each for a short duration of time in a set sequence. Therefore, the required generator capacity in kW is... Read more
Is battery technology – and its perceived high costs – slowing the widespread adoption of next-generation hybrid electric propulsion inthe marine world? “Today, the price of batter... Read more
High power generation is required on ships for cruise lines, tugs, tankers, and dredgers.The generator rating depends to a large degree on a fairly close assessment of peak power a... Read more
The shipboard power system design generally requires the following tasks: Selecting the optimum power system configuration and voltage level best suited for the ship Load analysis... Read more
AC power is now universally adopted all over the word because of its easy conversion from one voltage level to another using energy-efficient power transformers.From a large ac pow... Read more
Find and Correct the Cause of Trouble After any electrical failure on ship has been corrected by Electrotechnical Officer (ETO), be sure to locate and correct the cause so the same... Read more
Much of the work performed by Electrotechnical Officers (E.T.O.) involves the repair and maintenance of electrical equipment and systems. To maintain such systems at peak performan... Read more
The concept of electric propulsion is not new, the idea originated more than 100 years ago. However, with the possibility to control electrical motors with variable speed in a larg... Read more
