The cargo and container throughputs of port of Shanghai are both listed the first place in the world. However, with increase needs on port from the economic development, the growing development of the neighboring ports, the advent of 1.8×104 TEU container ships and 4×105 t bulk carriers, Shanghai Port's own natural constraints become increasingly apparent, especially the development of space is almost exhausted. In order to find the way out of Shanghai Port development, some preliminary work has been done, and the consensus is more appropriate for building new deepwater port in Hengsha. This paper analyzes the difficulties which Shanghai Port is faced with in detail, and finally conceives a development path based on the Hengsha east shoal in future.
