The invention provides a ship flexible connecting pipe safety state monitoring method, device and system. The method comprises the steps that the rotating speed of a sea water pump under the current ship working condition and acceleration information at the position of a flexible connecting pipe are obtained; acquiring the current axial displacement of the flexible connecting pipe corresponding to the rotating speed of the sea water pump and the acceleration information from a vibration isolation performance database of the flexible connecting pipe; the vibration isolation performance database stores the rotating speed of each candidate sea water pump and the experimental acceleration information of the flexible connecting pipe under each candidate axial displacement; and monitoring the safety state of the flexible connecting pipe based on the current axial displacement. The method, the device and the system provided by the invention solve the problem that the displacement measurement equipment is difficult to accurately measure the axial displacement due to the swinging operation of the ship, and the real-time performance and the reliability of the safety state monitoring of the flexible connecting pipe are realized by acquiring the accurate axial displacement in real time.
