electrical power in ships is usually produced by a synchronousgenerator. Given the essential nature of electrical poweronboard ship , several means are used to assure its continuousavailability. The main switchboard is divided into two or moresections. Also necessary are a switchboard supplied by anemergency generator as well as an uninterrupted (batterysecured) power supply (Figs. 2 and 3), both for reasons of safetyand to ensure the electrical networkThe first step is to define the ship type. It goes without saying thatthe vessel s size and purpose are key factors when dimensioning theship s electrical network. The following illustrate the differingelectrical needs of different types of ship :nCargo handling equipment plays a dominant role incontainerships, and defines the special power requirementcharacteristics of the electrical networknIn tankers, cargo pumps and possibly compressors are significantfactorsnIn passenger ships large electricity consumers are airconditioning, the galley equipment, stage equipment andlighting (also called hotel load) and the transverse thrusters formanoeuvring in portnIn ships
A battery or an uninterruptible power supply (UPS) must be provided as a standby power supply with a capacity of 30 minutes. Navigation and safety aspects (required by class) define the use of
