Abstract: The mining ship has a large opening, moonpool, in the middle of the ship, which runs through the hull bottom for drilling and mining, around which there are four evenly distributed mineral storage tanks. The mining ship has the common characteristics of the ore ship and the drilling ship. The ore ship adopts a square section design for its cross-section, which facilitates the input and output operations of minerals in the tank. The finite element (FE) analysis of the cabin is more convenient and faster than that of the whole ship. The internal and external loads of the mining ship are similar to those of the ore ship under the navigation state. Therefore, the finite element analysis of the cabin strength is carried out for the navigation state by using the CCS-HCSR-TOOLS software, with consideration of the structure type, modeling range, working condition selection and parameter setting according to the CCS code. The regions that should be noticed in the early design of the mining ship are obtained based on the calculation and analysis results. It can provide ideas for the structural design and strength analysis of the mining ship.
