The invention relates to the field of high-sulfur residual oil processing, and discloses a high-sulfur residual oil processing method, which comprises: (1) carrying out a hydrodesulfurization reaction on a mixed raw material containing high-sulfur residual oil and catalytic cracking heavy oil I to obtain a hydrodesulfurization reaction material flow; (2) separating the hydrodesulfurization reactant flow to obtain hydrogenated wax oil and hydrogenated reduced slag I; (3) carrying out a mild catalytic cracking reaction on the hydrogenated wax oil and a part of the hydrogenated reduced slag I to obtain a mild catalytic cracking reaction material flow; (4) separating the mild catalytic cracking reaction material flow to obtain catalytic cracking heavy oil I; and (5) blending a part of the catalytic cracking heavy oil I and a part of the hydrogenation reduced slag I to obtain the low-sulfur ship fuel. According to the method for processing the high-sulfur residual oil provided by the invention, the high-sulfur res
