  • In order to better protect the ocean and inland waterway environment and to enhance the monitoring of the ship bilge water discharge behaviors ,in conjunction with the international standards and characteristics of ships ,this paper discusses the necessity and feasibility on remote transmission of navigation ship oily water separator status informa‐tion based on AIS (automatic identification system ) .AIS message 12 and 14 are chosen as a transmission carrier of oily water separator status information .Complete oily water separator status information transmission interactive protocols are proposed in the study .The protocols define 6 types of messages :real‐time data ,request to send ,opening and closing sta‐tus ,historical drain situation ,user‐defined ,and conformation .The procedures of message encoding ,generating ,trans‐mitting ,and parsing are described and analyzed .The proposed message transmission method was tested under a simula‐tion experiment condition with obstructions of buildings and trees .The results indicate that packet error rate is about 30% ,and transmission is reliable to meet the needs of AIS communication .
