With the progress of economic globalization, international shipping trade is developing rapidly, resulting in a gradual rise in the volume of channel traffic. In turn, maritime affairs occur more frequently due to that than before, and the circumstance of transportation in channel is getting more and more complex. It has a great influence to the safety of ship navigation. This paper establishes a multilevel index system and constructs a fuzzy logic model based on fuzzy set to give an in-depth assessment on the channel safety. Previous researches show that fuzzy logic model can be used to manage multi-factor in safety assessment. However, the application for channel safety is an experiment and innovation. The model is applied to Yangtze Estuary deep water channel, and the output results are consistent with the practice. At the meantime，the assessment system has important value to make integrity planning of the channel.
