According to calculations, there is a certain proportional relationship between the actual amount of shipbuilding steel plate and the deadweight tonnage. Among them, the proportion of oil tankers is about 15%, the proportion of bulk carriers is about 20%, the proportion of container ships is about 30%, and the proportion of chemical tankers is about 30%. About 36%.
In 2009, China’s actual completed shipbuilding steel plate volume was 43 million tons in terms of deadweight tonnage. According to the above average ratio, the actual use of shipbuilding steel plate was about 10 million tons at most. Because the actual utilization rate of shipbuilding steel plate was about 90%, the actual demand for shipbuilding steel plate It is about 11.1 million tons and the annual export is about 4 million tons. From the current point of view, supply and demand are basically balanced compared with the output of 14.06 million tons.
The national shipbuilding industry adjustment and revitalization plan puts forward a target of 50 million tons/year of shipbuilding steel plate, which requires about 13 million tons of shipbuilding steel plate per year. In addition to the export of 4 million tons/year, the theoretical demand for shipbuilding steel plate is at most 2,000 10,000 tons/year, serious overcapacity.
