  We discuss the possible advantages of using the wavelet transform over the
Fourier transform for the early detection of rogue waves. We show that the
triangular wavelet spectra of the rogue waves can be detected at early stages
of the development of rogue waves in a chaotic wave field. Compared to the
Fourier spectra, the wavelet spectra is capable of detecting not only the
emergence of a rogue wave but also its possible spatial (or temporal) location.
Due to this fact, wavelet transform is also capable of predicting the
characteristic distances between successive rogue waves. Therefore multiple
simultaneous breaking of the successive rogue waves on ships or on the offshore
structures can be predicted and avoided by smart designs and operations.
