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.<>
