The need for storage and transportation facilities of liquefied natural gas have increased significantly because of global environmental regulations and recent shale gas innovation in North America. There is severe competition between Korea, Japan, and China for receiving manufacturing orders of LNG carriers or LNG storage tanks. Rationalization of the welding process used in the manufacturing of LNG facilities plays an important role in the above competition. This review paper presents the current global status and tendency for the development of latest welding technologies for LNG storage and transportation facilities. This article intends to present materials for raising the domestic competitive power for receiving manufacturing orders of LNG facilities.
