Abstract: The results of solving a linear problem on steady vibrations of a horizontal cylinder submerged in a fluid, whose upper boundary is partially closed by a solid lid, whereas the rest of the surface is free, are presented. Multipole and eigenfunction expansion methods are used. Reciprocity relations are derived. The added-mass and damping coefficients and the wave amplitudes on the free fluid surface are calculated.

Keywords: linear wave theory, submerged cylinder vibrations, non-homogeneous upper boundary, multipole expansion method, hydrodynamic load.
