The Radiation Problem of a Submerged Oblate Spheroid in Finite Water Depth Using the Method of the Image Singularities System
Round 1
Reviewer 1 Report
The problem of small motions of a submerged oblate spheroid in irrotational flow is studied. Semi-analytic results are obtained for the hydrodynamic coefficients, and compared with numerical results from a boundary integral equation code. This is an impressive piece of analysis, generally carefully described with useful results. It might have been interesting to see the results applied to some particular types of motion to illustrate the utility of the approach (or perhaps suggest what situations the approach could be applied to).
Some minor points below (with line number, where relevant)
Throughout I don’t think you need the . in Equation.(10), etc. Just Equation (10)
Around equations, avoid some of the indenting (this is still carrying on the same paragraph) and capital letters (e.g. where should often be lowercase).
Be consistent in use of commas and full stops around equations.

Reviewer 2 Report
In this paper, the researchers used the Image Singularities System to solve the radiation problem of an immersed axisymmetric oblate spheroid in a liquid field of fixed, finite, water depth. This method allows the expansions of the governing Green’s function into a series of spheroidal harmonics. The accuracy of the proposed method is verified by comparing with the calculation results of WAMIT by setting a variety of working conditions. The reviewer agrees to publish this work.
But there are some minor issues that you need to fix.
(1) Two commas appear in the edit of Equation. (5).
(2) The axis and legend fonts in the article are too small.
