The invention provides a real-time analysis system for the operation of a working ship based on ship attitude measurement, and the system comprises a central processing unit and a position monitoring unit, wherein the position monitoring unit is used for detecting and providing the position and attitude information and heading information of the working ship at a preset moment, and providing the position and attitude information and heading information of the working ship at the preset moment for the central processing unit; a manual data input unit which is connected with the central processing unit, and can provide pipe model data for the central processing unit in a mode of manual input; and a display unit which is connected with the central processing unit, and displaying the pipe dynamic response data according to the processed data provided by the central processing unit. The system carries out the call of real-time data measured by movement measurement equipment and working condition equipment for ship installation, transmits the data to finite element software, controls the finite element software to calculate the dynamic response of a pipe, can calculate the true response of the pipe more accurately, and brings convenience to a constructor for decision making.
