The provision of Ships Entry and Departure issued by China Port authority requires a ship to report its entry/depar-ture plan in specified time.In order to detect ships who fail to follow the regulations a technical solution is devised.The streaming data processing engine Apache Flink is used to check ships'berthing/unberthing operation against the ships'repor-ting data and find the ships who did not report its plan in specified time.An alarm will be announced if such a ship is found.The design has been used in a maritime information platform and worked well.
