  • the deck 5 include an exposed deck, a lower deck such as a freeboard deck provided below the exposed deck, and an upper deck provided above the exposed deck.
  • the loading pipe 30 is provided below the upper end 21t of the tank 21.
  • the height of the highest position of the loading pipe 30 can be suppressed as compared with the case where the loading pipe 30 is connected from the upper part of the tank 21 into the tank 21.
  • the pressure of the liquefied carbon dioxide L at the highest position of the loading pipe 30 is lower than the pressure of the liquefied carbon dioxide L stored in the tank 21 by the head pressure according to the height difference, but the loading pipe 30 By suppressing the height of the highest position of the loading pipe 30, it is possible to suppress the pressure drop of the liquefied carbon dioxide L at the highest position of the loading pipe 30.
  • the ship 1 according to the second aspect is the ship 1 of (1), and 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 using the loading pipe 30, gravity can be used depending on the position of the liquid level Lf. Therefore, it is possible to shorten the pump operation time for discharging liquefied carbon dioxide and to use a pump having a lower capacity, and as a result, it is possible to save energy and reduce the size of the pump. ..
  • the ship 1 according to the third aspect is the ship 1 of (2), and the pipe end 32t of the second portion 32 connected to the lower end 21b of the tank 21 is the lower end of the tank 21. It is provided at the same height as the inner peripheral surface 21f of 21b in the vertical 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 vertical direction to reduce the liquefied carbon dioxide L in the tank 21.
  • the amount of liquefied carbon dioxide L remaining in the tank 21 can be suppressed.
  • the vessel of the present disclosure it is possible to suppress the generation of dry ice in the loading pipe and smoothly operate the tank.

Abstract

La présente invention concerne un navire comprenant une coque, un réservoir et un tuyau de chargement. La coque a une paire de côtés larges et un pont. Au moins une partie du réservoir est disposée de manière à faire saillie au-dessus du pont, le réservoir pouvant stocker du dioxyde de carbone liquéfié. Le tuyau de chargement est disposé au-dessous du bord supérieur du réservoir. Le tuyau de chargement charge le dioxyde de carbone liquéfié fourni depuis l'extérieur du navire, vers l'intérieur du réservoir. Le tuyau de chargement comprend une première section et une seconde section. La première section s'étend le long du pont. La première section a une section qui se couple à l'extérieur du navire. La seconde section s'étend vers le bas à partir de la première section. La seconde section est reliée à un bord inférieur du réservoir.
