Abstract The global financial crisis has a huge impact on the shipbuilding industry, making the world shipbuilding enterprises in all aspects launched a fierce competition。 Countries left behind the South Korea, Europe and the United States and other countries in all aspects of technology, management, quality must seize the high technology, high added value, profit margins of liquefied gas carrier as a breakthrough to achieve key success in the competition。

In this paper, we start with introducing the background of the shipbuilding industry, the status quo of domestic and foreign liquefied gas carriers and significance of the research, and then summarize the classification, characteristics, development status and trend of the liquefied gas tanker。 Based on the present situation and development of liquefied gas tanker and ship's production design, the production design of the 303 section of the bottle of the cargo tank of the 27500 liquefied gas tanker is carried out in combination with the actual production and processing capacity and production flow。 Referring to basic structure diagram, piecewise graph partitioning, general layout, transverse profile and construction principles, we point out the  construction essentials, draw sub structure, splicing board diagram and parts list, set the hoisting rings, calculate weight and center of gravity and draw section installation diagram of rings, at the  same time discuss structure characteristics and future trends of the liquid of gas ship。
