• wherein side walls (5) in lower areas of the ship are of hollow construction due to the addition of a hollow area (HR) to an inside of the side walls, the hollow area (HR) producing a stepped cargo space (SR) in the lower areas of the ship, wherein the pallet vehicle (RFZ) traveling in a transverse direction of the ship travels up to a vertical inner side (5a) of one of the side walls and then above the hollow area (HR) into an above-positioned cargo space (SR1) set to an outside of the ship, and up to the side wall (5) vertical outer side (5b) connected to the hollow area (HR) to permit storage and removal of pallet units (PE) by the satellite vehicle (4).
