Description

The present invention relates to ships.

Ships such as ships are equipped with electric wires, pipes, ventilation ducts, and the like inside the ship. Electric wires supply electric power from a generator to equipment such as various devices and equipment used inside the ship. Piping passes fluids such as water supply, hot water supply, and drainage. The ventilation duct performs air conditioning, ventilation, air supply and exhaust, etc. These electric wires, pipes, and ventilation ducts are generally arranged along the lower side (attic) of the deck provided inside the ship, the inner side surface on the side provided on both sides in the width direction of the ship, and the like.

In this way, the electric line 20E, the piping line 30P, and the ventilation duct 30D are alternately arranged in the first layer 101, the second layer 102, and the third layer 103 in the ship width direction Dw. In the unlikely event that the side 4 is damaged on either side of the ship width direction Dw, it is possible to prevent the electric line 20E, the piping line 30P, and the ventilation duct 30D from being all damaged at the plurality of layers 100. As a result, even when the hull 2 is damaged, the function of the ship 1 can be maintained and the navigation can be continued.

Further, the ship 1 further includes a central electric line 20Ec arranged at the center of the ship width direction Dw. As a result, the electric wires Le, whose number is increasing due to the computerization of equipment, are arranged on the starboard side or starboard side of the ship width direction Dw, and the central electric line 20Ec in the center of the ship width direction Dw. Therefore, it is possible to accommodate a large number.

Further, the electric wire 20E is provided with electric wire relay members 50 at a plurality of places spaced apart from each other in the stern direction Da. As a result, by removing a part of the electric wire Le extending in the stern 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 through the opening 45 formed on the side 4. You can avoid interfering.
Further, also in the piping passage 30P and the ventilation duct 30D, by removing the pipeline member 31 forming a part of the piping passage 30P and the ventilation duct 30D, the equipment carried in from the opening 45 interferes with the piping passage 30P and the ventilation duct 30D. You can avoid doing it.

Further, the ship 1 can easily install the electric line 20E, the piping line 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 the electric line 20E, the piping line 30P, and the ventilation duct 30D are newly installed after being laid. The work can be done easily.

Further, the ship 1 has an electric line 20E extending in the stern direction Da, a piping line 30P, and a branch path 90 branching from the ventilation duct 30D.
