✦ Synopsis

Alternative approaches to stochastic dynamic response analysis of submerged ¯oating tunnels subjected to wave loading are presented. For the purpose of establishing force, damping and mass coecients for structural elements with three-dimensional ¯ow conditions, ¯uid/structure interaction is modeled as ®nite element implementation of the Navier±Stokes equation. The numerical examples emphasize the eects of wave direction, shortcrestedness, damping, geometrical stiness and frequency dependence in mass and damping coecients.

## Abstract The modified ghost fluid method (MGFM) developed by Liu __et al__. (__J. Comput. Phys__. 2003; **190**:651–681) provides us a robust method to treat moving compressible gas–gas and gas–liquid interfaces. Recently, the MGFM was extended to treat compressible fluid‐compressible structure
