  • a pipe end 32t of the tank connection portion 32c is connected to a communication opening 21h formed at the lower end 21b of the tank 21.
  • the communication opening 21h makes the inside and the outside of the tank 21 to communicate with each other at the lower end 21b of the tank 21.
  • the pipe end 32t of the second portion 32 is provided at the same height as an inner peripheral surface 21f at the lower end 21b of the tank 21 in the up-down direction Dv.
  • the pipe end 32t of the second portion 32 does not protrude toward the upper side (in other words, the inside of the tank 21) with respect to the inner peripheral surface 21f at the lower end 21b of the tank 21, and is provided to be flush with the inner peripheral surface 21f.
  • the pipe end 32t of the second portion 32 is open vertically upward on the inner peripheral surface 21f at the lower end 21b of the tank 21.
  • the second portion 32 is connected to the lower end 21b of the tank 21.
  • the second portion 32 is connected to the lower end 21b of the tank 21 from vertically below.
  • the loading pipe 30 as described above discharges the liquefied carbon dioxide L, which is supplied from the outside of the ship, into the tank 21 from the lower end 21b of the tank 21.
  • the loading pipe 30 is provided on the lower side with respect to the upper end 21t of the tank 21. In this way, a height difference ⁇ h between a liquid level Lf of the liquefied carbon dioxide L in the tank 21 and the first portion 31 which is at the highest position of the loading pipe 30 can be reduced as compared with a case where the loading pipe 30 is connected into the tank 21 from the upper portion (the upper end 21t) of the tank 21.
  • the first portion 31 of the loading pipe 30 is provided above the deck 5.
  • the second portion 32 of the loading pipe 30 is connected to the lower end 21b of the tank 21 from below. Therefore, for example, when the liquefied carbon dioxide L in the tank 21 is discharged from the tank 21 by using the loading pipe 30, gravity can be used depending on the position of the liquid level Lf. Therefore, it becomes possible to shorten a pump operation time for discharging liquefied carbon dioxide or to use a pump with a lower capacity, and as a result, it becomes possible to save energy and reduce the size of the pump.
  • the pipe end 32t of the second portion 32 of the loading pipe 30 is provided at the same height as the inner peripheral surface 21f at the lower end 21b of the tank 21 in the up-down direction Dv. Therefore, when the liquefied carbon dioxide L in the tank 21 is discharged, the amount of the liquefied carbon dioxide L remaining in the tank 21 can be suppressed.
  • the loading pipe 30 may be provided such that a plurality of tanks 21 are connected to one loading pipe 30.
  • the second portion 32 that is connected to each tank 21 may be provided to be branched from the first portion 31 of the loading pipe 30. That is, in a case where the plurality of tanks 21 are connected to one loading pipe 30, the loading pipe 30 includes one first portion 31 and a plurality of second portions 32.
  • a valve (not shown) or the like for interrupting the supply of the liquefied carbon dioxide L to the tank 21 may be provided at each of the second portions 32.
  • the under-tank extension portion 32b and the tank connection portion 32c which are connected to each tank 21 may be connected to the first portion 31 and the downward extension portion 32a of the second portion 32 of the loading pipe 30. That is, the loading pipe 30 may be made such that a plurality of under-tank extension portions 32b and tank connection portions 32c are branched from and connected to the first portion 31 and the downward extension portion 32a of the second portion 32 of one loading pipe 30. Also in this case, a valve (not shown) for interrupting the supply of the liquefied carbon dioxide L to the tank 21 may be provided in each of the under-tank extension portion 32b and the tank connection portion 32c that are connected to each tank 21.
  • the plurality of tanks 21 are connected to each other through the under-tank extension portions 32b and the tank connection portions 32c.
  • the plurality of tanks 21 are connected to each other through the under-tank extension portions 32b and the tank connection portions 32c in this manner, if the heights of the liquid levels Lf of the liquefied carbon dioxide L are different from each other between the plurality of tanks 21, the liquefied carbon dioxide L can be exchanged through the under-tank extension portions 32b and the tank connection portions 32c.
  • the first portion 31 of the loading pipe 30 is provided so as to extend above the deck 5 (all-decks exposed to the outside).
  • the first portion 31 of the loading pipe 30 may be provided to follow a deck other than the deck 5, for example, an upper deck provided above the deck 5 or a lower deck such as a freeboard deck provided below the deck 5.
  • the tank 21 is provided so as to straddle both the spaces above and below the deck (the upper deck or the lower deck) provided with the first portion 31 of the loading pipe 30 and at least the upper end 21t protrudes to the upper side of the deck.
  • the ship 1 described in the embodiment is grasped as follows, for example.
  • the ship 1 includes: the hull 2 having the pair of broadsides 3A and 3B and the deck 5; the tank 21 having at least a part provided to protrude to the upper side with respect to the deck 5, and capable of storing the liquefied carbon dioxide L; and the loading pipe 30 that is provided on the lower side with respect to the upper end 21t of the tank 21 and loads the liquefied carbon dioxide L, which is supplied from the outside of the ship 1, into the tank 21, in which the loading pipe 30 includes the first portion 31 extending above the deck 5 and having the connection part 31j for connection with the outside of the ship 1, and the second portion 32 extending downward from the first portion 31 and connected to the lower end 21b of the tank 21.
  • an exposure deck As the example of the deck 5, an exposure deck, a lower deck such as a freeboard deck provided below the exposure deck, an upper deck provided above the exposure deck, and the like can be given.
  • the loading pipe 30 is provided on the lower side with respect to the upper end 21t of the tank 21. In this way, the height of the highest position of the loading pipe 30 can be reduced as compared with a case where the loading pipe 30 is connected into the tank 21 from the upper portion of the tank 21.
  • the pressure of the liquefied carbon dioxide L at the highest position of the loading pipe 30 is lowered by the amount corresponding to a head pressure according to the height difference with respect to the pressure of the liquefied carbon dioxide L stored in the tank 21.
  • the height of the highest position of the loading pipe 30 is reduced, so that it is possible to suppress a decrease in the pressure of the liquefied carbon dioxide L at the highest position of the loading pipe 30.
  • the second portion 32 is connected to the lower end 21b of the tank 21 from below.
  • the second portion 32 of the loading pipe 30 is connected to the lower end 21b of the tank 21 from below. Therefore, for example, when the liquefied carbon dioxide L in the tank 21 is discharged from the tank 21 by using the loading pipe 30, gravity can be used depending on the position of the liquid level Lf. Therefore, it becomes possible to shorten a pump operation time for discharging liquefied carbon dioxide or to use a pump with a lower capacity, and as a result, it becomes possible to save energy and reduce the size of the pump.
  • the pipe end 32t of the second portion 32 that is connected to the lower end 21b of the tank 21 is provided at the same height as the inner peripheral surface 21f of the lower end 21b of the tank 21 in the up-down direction.
  • the upper end 21t of the second portion 32 of the loading pipe 30 is provided at the same height as the inner peripheral surface 21f at the lower end 21b of the tank 21 in the up-down direction, and therefore, when discharging the liquefied carbon dioxide L in the tank 21, the amount of liquefied carbon dioxide L remaining in the tank 21 can be suppressed.
