I. Characteristics of LNG carriers
Storage and transportation of liquefied natural gas
LNG carriers are mainly used to store and transport LNG. Because LNG needs to be stored at extremely low temperature, LNG carriers must have special thermal insulation design and efficient cooling equipment to ensure that the temperature of storage tanks on board will not rise. In addition, LNG carriers need special leakage monitoring equipment to ensure the safety during transportation.
Efficient fuel system
LNG ships usually use dual-fuel engines and can use liquefied natural gas or diesel as fuel. Compared with traditional diesel ships, LNG ships can reduce fuel consumption and carbon emissions, and have better environmental protection performance.
Large design
LNG carriers usually adopt large-scale design to improve transportation efficiency and capacity. The volume of LNG ships is generally between 654.38+00000-20000 cubic meters, and the storage capacity of the largest LNG ship can even reach 260000 cubic meters.
2. Which countries can manufacture LNG carriers?
LNG carrier is a high-tech ship, and its manufacture requires professional technology and equipment, so only a few countries can manufacture this kind of ship. The following are the main countries that can manufacture LNG carriers at present:
Japan
Japan is the leader in the global LNG ship manufacturing industry, accounting for more than 70% of the global LNG ship manufacturing market. Japan's shipbuilding industry developed earlier and its technology and equipment were relatively mature. Its shipbuilding enterprises have accumulated rich experience and technology in LNG ship manufacturing.
South Korea
South Korea is another big LNG ship manufacturing country, and its shipbuilding industry also has a high reputation in the world. South Korean shipbuilding enterprises have also accumulated a lot of experience and technology in producing high-quality LNG ships. Korean LNG carrier manufacturers, including Daewoo Shipbuilding, Hyundai Heavy Industries and Samsung Heavy Industries, occupy an important position in the global LNG carrier manufacturing industry.
China In recent years, China's shipbuilding industry is also gradually rising, and China has become one of the important countries in LNG shipbuilding in the world. China shipbuilding enterprises, including CSIC, CNOOC and China Shipbuilding Industry Corporation, have accumulated rich experience in the design, manufacture and modification of LNG carriers. In particular, the manufacturing level of CSIC LNG carrier has reached the advanced level in the world, and its ship design and technical performance have been widely recognized in the international market.
European and American countries are also one of the important countries in LNG shipbuilding, such as Norway, France, Germany and the United States. Shipbuilding enterprises in these countries have rich experience and technology in the field of LNG ship manufacturing, and constantly promote technological innovation and research and development to meet the growing LNG ship market demand.
Generally speaking, LNG carrier is a high-tech ship, and its manufacture needs professional technology and equipment. At present, the main countries that can manufacture LNG carriers are Japan, South Korea, China, Europe and America. Shipbuilding enterprises in these countries have accumulated rich experience in the design, manufacture and modification of LNG ships, and can produce high-quality LNG ships. With the continuous expansion and development of the global LNG market, the market demand for LNG carriers will continue to grow, which will further promote the technological innovation and development of shipbuilding enterprises in various countries.
