[0030] Example

[0031] In this embodiment, the preparation room 1 is arranged on the main deck layer, which is used to store various types of unmanned submersibles, including small unmanned submersibles 61, medium unmanned submersibles 62 and large unmanned submersibles 63, and to prepare the unmanned submersibles before performing tasks. The auxiliary transfer device 2 is a rail-type trolley. The fireproof roller shutter partition wall 21 between the preparation room 1 and the hoisting room 3 is lowered as a channel isolation when not in a mission state, and is raised and opened when the unmanned submersible is transported, so as to facilitate the unmanned submersible in the preparation room 1 to move away.
