The invention relates to a method for producing a hot-rolled steel coil for shipbuilding, which comprises the following steps of: 1) designing components, pretreating molten iron, smelting in a converter, switching nitrogen and argon, and tapping to obtain molten steel; 2) performing continuous casting on the molten steel to obtain a plate blank, wherein the content of the molten steel in a continuously cast intermediate ladle is controlled to be between 8 and 15t and the liquid level is controlled to be between 200 and 350mm when the intermediate ladle is not poured; and pouring is protectedin the whole process, and the insertion depth of a long nozzle is between 300 and 400mm; 3) heating the plate blank; and 4) rolling and curling the heated plate blank. By the method, the content of Cand Mn in the components of grade E steel is reduced, the comprehensive performance of the grade E steel is improved by appropriate rolling process and controlled cooling process, and a low-cost and high-performance grade E hot-rolled steel coil is produced.
