The shore-to-ship power system is arranged with the shore connection panel located outside the main switchboard room with cable connectors mounted in the front. Electricity has to be distributed with minimal losses after generation. 0000083706 00000 n Unlike a shore based transmission system, where the lengths of the conductors run throughout a country, a shipboard electrical distribution system is short and simple. That’s why all important systems and their components require approval when a ship is classified according to DNV GL rules. 1-1. Relevant work in the engine room and the bridge and the influence of the system are discussed. The correct sizing of the generator is the key to a safe, workable and economic electrical system.
