The main priority onboard is the safety of ship which includes navigation & fire safety..etc. USS Trenton, was, as SS Columbia, a modern ship featuring both steel hull and a steam propulsion system with additional sailing rigs. On board a metallic ship “Earth” is the hull and superstructure and as a consequence it is everywhere. The ship's electrical network enables the ship to operate as an independent entity at sea and often also in port. the ship’s main switchboard.. The DC distribution system has been proposed, as a replacement for the present AC power distribution system for ships with electric propulsion.. The distribution of electric power to different consumers is done with a much lower voltage level compared to the transmission of power over long distances (i.e. Electrical Plant and Distribution System for Ships A.C. Generators Alternating current is a form of electricity in which the current alternates in direction (and the voltage alternates in polarity) at a frequency defined by the generator (usually between 50 and 60 times per second, i.e., 50 – 60 hertz). without considering ship power system ohmic losses [9-10]. ship depends upon electric power for its.
