1. 5 Basic Maintenance Principles
    • The worker must have a process that guides the performance of maintenance.
    • The worker must be trained so that work can be done safely and effectively.
    • The worker must have the proper technical direction.

  21. Purpose of Degaussing
    Degaussing system counteracts or neutralizes the magnetic fields produced by permanent and induced magnetization of ship and thereby makes the ship magnetically invisible
  22. Factors influencing permanent magnetism
    • Amount and type of material used during ship’s construction.
    • Location (latitude) where the ship was built.
    • Ship's heading during construction.
    • Permanent magnetism is constant and is independent of  ship’s position (latitude) and heading.
  23. Factors affecting induced magnetism
    • The magnetic latitude in which the ship is operating
    • The ship's heading
  24. How do we degauss?
    DC potential applied coils around ship to establish electromagnetic fields to counteract the ship's permanent and induced magnetic fields.
