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

摘要

A regasification-capable natural gas hydrate (NGH) transportation ship (1) is provided with NGH cargo holds (10), a heat exchanger (22) for supplying heat to circulating water, and a circulation pump (21) for circulating the circulating water between the NGH cargo holds (10) and the heat exchanger (22), wherein a gas discharge pipe (11) and a circulating water spraying device (13) are disposed above the NGH cargo holds, and a circulating water descending pipe (16) for guiding the circulating water within the NGH cargo holds (10) from an opening (16a) to a circulating water pipe (18) via a discharge pipe (17) disposed below the bottom (10a) of the NGH cargo holds (10) is disposed within each NGH cargo hold (10). As a consequence, the NGH pellets within the NGH cargo holds (10) of the NGH transportation ship (1) can be stably and effectively regasified with a simple structure.
