EMC requirements for ships

The EMC environment on a ship is sufficiently different other EMC environments justify specific EMC standards. A ship has machinery propulsion, manoeuvring cargo management which involve high powers at electrical power frequency. It also has navigation equipment, communication equipment and control equipment associated with it´s machinery. The radio frequencies that can be utilised on a ship cover a wide band from 10 kHz for Omega to 9 GHz for radar. The bridge of a ship is a particularly dense concentration of radionavigation, radiocommunication and machinery control equipment which all has to work together
