Shipboard Electrical Grounding Training Overview
Modern Naval and marine vessels carry dense concentrations of power, communication, navigation, and weapons systems. As new electrical and electronic systems are added, they contribute to a complex electromagnetic environment and can become susceptible to EMI. In parallel, ships operate in a harsh, corrosive saltwater environment, where the metallic hull, superstructure, topside hardware, and antenna systems interact electrically.
These factors significantly increase the potential for interoperability problems, nuisance upsets, data corruption, shock hazards, and accelerated corrosion. Effective shipboard grounding and bonding practices are essential for controlling ground potential, managing return currents, reducing electromagnetic coupling, and maintaining the safe operation of shipboard power systems and electronics.
This course explains how to establish and maintain a low-impedance common reference ground for shipboard electrical and electronic equipment. It examines the effects of natural and man-made electromagnetic energy, both on-ship and off-ship, and shows how proper grounding, bonding, and shielding practices can mitigate EMI, improve electromagnetic compatibility (EMC), and enhance personnel safety. The training also addresses the impact of power line disturbances on communications, the fundamentals of lightning and surge protection, and the role of grounding in corrosion control.
