Electromagnetic compatibility in the mercantile marine situation

Some idea of the magnitude of the problem of electromagnetic interference and methods of its propagation on board ship are given. The present situation relating to marine e.m.c. specifications is described and the need for agreed and accepted marine e.m.c. specifications, not only nationally but internationally, is proposed. Present installation techniques and measures used to minimize interference on commercial marine installations is given. Specific examples of interference at sea are quoted and some details of a proposed I EC specification are listed. An example is given of the e.m.c. design of a compact radio telephony equipment.
