Effects of LNG- Tank Sloshing on the Global Motions of LNG Carriers

Introduction Schematic diagram of sloshing of two-dimensional wave is very important for many years and has been extensively studied in many engineering fields. Wave fluctuations can be explained as movement of waves in the affected part. More specifically, the wave sway is the wave height and its frequency over time. Sloshing affects the movement of the ship finally for sea supply vessels (LNG carriers) that transport natural gas in particular and may seriously damage the container walls and hull structure, Sloshing is very dangerous for shipping containers.

Marine transportation: The main method of LNG maritime transport is the use of LNG barges or small LNG carriers. Compared to world class LNG shipments, small LNG carriers and carriers are expected to meet the same regulations, designs and standards. Overseas relocation of LNG has a safe record and more than 75,000 items worldwide are shipped from the export terminal to land and offshore reception terminals. LNG carriers need to comply with the requirements of the International Maritime Organization (IMO) and the International Gas Carrier Regulations (IGC), as well as the government imposed requirements.

LNG ship is a highly specialized expensive ship. The construction of freight tanks and marine machinery requires considerable technical know-how, and the EU shipyard has historically played an important role in this market field. From 1990 to 1998, 63% of all shipments of LNG were shipped to Japan, the EU accounted for 27%, Korea accounted for 10%. Currently, orders for LNG carriers are 43% in Japan and 57% in Korea. There is no order in the EU. This is another example of Korea's entry into the high-value market segment previously held by Japan and the European Union. It is worth noting that the same shipbuilding yard builds a similar ship for state-owned Korean gas companies. The price is $ 22.2 billion. Dollar compared to the price of $ 165. USD against customers other than Korea
