As shown in FIG. 5, the electric wire relay member 50 includes a terminal block 52 to which a connection terminal 51 provided at an end portion of the electric wires Le adjacent to each other in the bow / tail direction Da is detachably connected.
Moreover, as shown in FIG. 4, the electric circuit 20E which makes a cylindrical shape is comprised by connecting the some cylindrical member 21 along the fore-and-aft direction Da. The cylindrical members 21 that move back and forth in the fore-and-aft direction Da are detachably connected via a flange portion (not shown).

  In such a configuration, by removing the connection terminal 51 of each electric wire Le from the terminal block 52, it is possible to remove the electric wire Le in part of the bow-stern direction Da. Moreover, the cylindrical member 21 which comprises the electric circuit 20E can be removed in part of the fore-and-aft direction Da by separating the cylindrical members 21 which are mutually back and forth in the fore-and-aft direction Da with a flange portion. .

  As shown in FIG. 3, the pipeline 30 </ b> P and the ventilation duct 30 </ b> D are configured by a plurality of pipeline members 31 connected in the fore / aft direction Da.

The road member 31 can be removed.

  After laying the electric path 20E, the pipe line 30P, and the ventilation duct 30D, for example, the equipment installed in the hull 2 may be added or changed. In such a case, as shown in FIG. 4, depending on the size of the equipment, an opening 45 may be formed on the side 4 and the equipment may be carried into the hull 2 through the opening 45. When the equipment to be carried in interferes with the electric path 20E, the piping path 30P, and the ventilation duct 30D, as described above, the electric wire Le, the electric path 20E, the piping path 30P, and the ventilation duct 30D are partially connected in the bow-stern direction Da. Remove. Thereby, it can avoid that the equipment to carry in interferes with the electric circuit 20E, the piping line 30P, and the ventilation duct 30D.

  Therefore, according to the ship 1 of the first embodiment described above, in each layer 100 between the decks 6 adjacent to each other in the vertical direction, the electric path 20E through which the electric wire Le is inserted is arranged on one side in the ship width direction Dw. The piping 30P and the ventilation duct 30D constituting the piping 30P and the ventilation duct 30D are arranged on the other side. Thus, by arranging the electric wire Le, the piping path 30P, and the ventilation duct 30D separately, it is possible to prevent the layout of the electric wires Le, the piping path 30P, and the ventilation duct 30D from becoming complicated. Therefore, the layout and laying of the electric wire Le, the piping path 30P, and the ventilation duct 30D, and the addition and change of the laid electric wire Le, the piping path 30P, and the ventilation duct 30D can be easily performed.

Further, in the ship 1, in the first hierarchy 101, the electric circuit 20E is disposed on the starboard side in the ship width direction Dw, and the piping 30P and the ventilation duct 30D are disposed on the port side in the ship width direction Dw.

In addition, in the third hierarchy 103, the electric circuit 20E is arranged on the starboard side in the ship width direction Dw, and the piping 30P and the ventilation duct 30D are arranged on the port side in the ship width direction Dw.
Thus, in the first hierarchy 101, the second hierarchy 102, and the third hierarchy 103, the electric circuit 20E, the piping 30P, and the ventilation duct 30D are alternately arranged in the ship width direction Dw. If the dredging side 4 is damaged on either side in the ship width direction Dw, it is possible to prevent the electric path 20E, the pipe line 30P, and the ventilation duct 30D from being damaged at the plurality of levels 100. As a result, even when the hull 2 is damaged, the function of the ship 1 can be maintained and navigation can be continued.

  Furthermore, the ship 1 further includes a central electric circuit 20Ec disposed at the center of the ship width direction Dw. As a result, the electric wires Le whose number tends to increase with the digitization of equipment are connected to the electric circuit 20E arranged on the starboard side or starboard side in the ship width direction Dw, and the central electric circuit 20Ec in the center part of the ship width direction Dw Thus, a large number can be accommodated.

Moreover, the electric circuit 20E is equipped with the electric wire relay member 50 in the several place spaced apart in the bow / tail direction Da. Thereby, by removing a part of the electric wire Le extending in the fore-and-aft direction Da from the electric wire relay member 50, the electric wire Le is attached to the equipment when the equipment is carried into the hull 2 from the opening 45 formed on the shore side 4. Interference can be avoided.
Further, also in the pipe line 30P and the ventilation duct 30D, by removing the pipe member 31 constituting a part of the pipe line 30P and the ventilation duct 30D, the equipment carried in from the opening 45 interferes with the pipe line 30P and the ventilation duct 30D. You can avoid doing it.
Therefore, it is possible to additionally install larger equipment in the hull 2 even after the electric wire Le, the electric circuit 20E, the piping line 30P, and the ventilation duct 30D are laid.

  Further, in the ship 1, a girder member 80 having a U-shaped cross section or a cross-sectional box shape is joined to the lower side of the deck 6. The deck 6 can be reinforced by the girder member 80 that accommodates the electric path 20E. Thus, the girder member 80 has a function of accommodating the electric path 20 </ b> E and a function of reinforcing the deck 6.

  Furthermore, the ship 1 can easily install the electric path 20E, the piping path 30P, and the ventilation duct 30D through the opening 75 formed in the reinforcing beam 70 on the lower side of the deck 6. By forming such an opening 75 in advance, it is necessary to newly open the opening 75 when newly installing these after laying the electric circuit 20E, the pipe line 30P, and the ventilation duct 30D. The work can be easily performed.

  Moreover, the ship 1 has the branch path 90 branched from the electric path 20E, the piping path 30P, and the ventilation duct 30D which are extended in the bow / tail direction Da. The electric wire Le, the pipe line 30P, and the ventilation duct 30D can be connected to the equipment arranged in each part in the hull 2 via the branch path 90.
