Seabed mining ship .

摘要

To provide a seabed mining ship can perform cheaply mined by less energy. A high-pressure hydrogen tank 14, it is placed in the boat body 11, it is provided to allow storage of high-pressure hydrogen gas. Drilling elevating part 21 is vertically movably provided from the ship body 11 to the seabed 1, a hydrogen gas receivable and is dischargeable in a hydrogen gas to a high-pressure hydrogen tank 14 from the high-pressure hydrogen tank 14, is connected to the high-pressure hydrogen tank 14 there. Drilling elevating part 21, the seawater has a possible out opening 31a, and the seawater storing chamber 31 provided in the seawater to be housed, adjacent to the sea water storage chamber 31, storage of hydrogen gas from the high-pressure hydrogen tank 14 a hydrogen storage chamber 32 for a water storage chamber 31 and the hydrogen storage chamber 32 and the elastic partition membrane 33 provided so as to partition the, and drilling means 35 provided a submarine one possible drilling, drilling by the drilling means 35 The recovered objects and a Atsumariko means 36 provided to be capturing the opening 31a in the sea water storage chamber 31.
