Surveilance of ship movements

    The diagrams below depict data of measurements of ship movement and an evaluation of these data from the start of a voyage from Hamburg for the ship, Fuji Star.

    • Diagram 1 shows a series of data registrations of ship movement over a period of 100 seconds.
    • Diagram 2 shows a spectral analysis of these data.

    The analysis indicates that Fuji Star is fairly stable and not in danger of capsizing at this time.


    Diagram 1: Ship movement registration
  • Vertical: angle in degrees
  • Horisontal: time in seconds

Diagram 2: Spectral analysis:

  • What is the cycle time?
  • What is the frequency?
