REGASIFICATION-CAPABLE NGH TRANSPORTATION SHIP, AND NGH REGASIFICATION METHOD IN NGH TRANSPORTATION SHIP

摘要

PROBLEM TO BE SOLVED: To provide a regasification-capable NGH (natural gas hydrate) transportation ship, having a simple structure to stably and efficiently regasify NGH pellets in an NGH cargo hold of the NGH transportation ship, and to provide an NGH regasification method in the NGH transportation ship.

SOLUTION: The NGH transportation ship includes: the NGH cargo hold 10; a heat exchanger 22 supplying heat to circulating water; and a circulation pump 21 circulating the circulating water between the NGH cargo hold 10 and the heat exchanger 22. A gas discharge pipe 11 and a circulating water spraying device 13 are disposed above the NGH cargo hold 10, and a circulating water descending pipe 16 is disposed inside of the NGH cargo hold 10 so that the circulating water in the NGH cargo hold 10 is lead from an opening part to a circulating water pipe 18, through a discharge pipe 17 disposed below the bottom 10a of the NGH cargo hold 10.
