Abstract: A detailed literature review on vibro-acoustic modeling of complex underwater cylindrical shell structure is given, in both aspects of research objects and modeling approaches. Reviews on infinitely long and finitely cylindrical shell, double layer cylindrical shell, ribbed cylindrical shell, and the cylindrical shell with internal bases (floors, foundations etc) and complex vibration isolation system are presented. Methods for modeling dynamic responses of fluid-loaded cylindrical shell in low frequency, mid-frequency and high frequency ranges are given. Some potential modeling techniques are provided.

Key words: vibration and wave, complex underwater cylindrical shell structure, fluid-structure interaction, coupled finite element method and boundary element method
