Abstract
Natural Gas Hydrate (NGH) can be carried at much higher temperature than LNG (ca. 112K) by self-preservation effect. Thus, not only the running cost but also the initial cost of NGH production plant will be saved in comparison with LNG plant. We studied the NGH transporting system in the form of NGH pellet (NGHP). NGHP is solid in spherical shape and has good handling for loading to NGH carrier. A suitable combination of different sized pellets can improve the filling efficiency in cargo hold of NGH carrier.
