Abstract : In January 1991 the Naval Oceanographic and Atmospheric Research Laboratory (NOARL) Code 252 undertook to investigate for NAVSEA PMS 400D52 the possibility of communicating data through a ship's bulkhead without penetrating the bulkhead physically. Four possible methods of transmission were identified; ultrasonic, electric current injection, magnetic coupling, and current carrier. Of these, the electric current injection method was selected as the most promising, and a device using this technique was developed.
