This paper introduces the design method of the port plane layout in the Russian port design code，namely Standards for the design of sea channels，fairways and maneuvering areas and analyzes the design differences between the Russian code and the Chinese code，namely Design Code of General Layout for Sea Ports through the case calculation.There are similarities between the two codes in terms of port plane layout，while differences in the basin width，berthing water width，and channel width remain，which is of guiding significance for similar practical engineering applications.
