A submerged sphere advancing at constant forward speed in deep water with an ice-cover is analyzed by linear potential theory, with the ice-cover being modeled as an elastic plate of small thickness. The problems of radiation (surge, sway and heave) of the flexural-gravity waves by a submerged sphere are investigated. Method of multipole expansions is used. Numerical results are obtained for the radiation load: added-mass and damping coefficients. When the flexural rigidity and the density of the ice-cover are taken to be zero, the numerical results for the hydrodynamic load for water with a free surface are recovered.
Keywords: radiation problem at forward speed, ice-cover, submerged sphere, added mass, damping coefficient.
