The present study characterizes the impact of brash ice present at the topmost surface of an ocean on a submerged stationary prolate spheroidal body (both axisymmetric and nonaxisymmetric) within the framework of linear water wave theory. The brash ice cover is assumed to behave as an inertial surface composed of uniformly distributed, noninteracting particles in the presence of surface tension. Taking advantage of the body’s symmetry, we adopt a prolate spheroidal coordinate system. The solution is constructed through the method of image singularities, using Havelock’s theorem to transform the fundamental Green’s function into a prolate spheroidal coordinate system. The diffraction potentials are expanded in terms of the multipoles of the Green’s function using spherical harmonics. The zero-velocity condition, along with suitable orthogonality relations, is used to derive the final linear system. The hydrodynamic forces (such as surge, heave and sway) and moment acting on the spheroid are numerically evaluated, and analysed for different values of the brash ice parameter, coefficients of surface tension, depths of submergence, eccentricity of the body and wave-heading angles. We observe reduction in the magnitudes of forces due to the presence of brash ice and further reduction has been noticed as the layer of brash ice gets heavier. The yaw moment is found to attain its maximum value at a specific angle of wave incidence.
