Method for energy saving, safety managing and maintenance information offering of the marine structure by real time predicted monitoring and controlling gas-dynamic

摘要

The present invention relates to monitoring and controlling external forces, hull stress, 6-degree-of-freedom motion and position in an aerodynamic environment for an offshore structure in real time. More particularly, It is a comprehensive method to measure the change of slope, draft, trim, corrosion, erosion, crack, pressure, stress, vibration and frequency and control the above offshore structure based on this to provide fuel saving, safe operation and maintenance information . According to one aspect of the present invention, data on the external and internal forces of the external structure of the offshore structure via the external structure of the offshore structure and the data on the reactions of the offshore structure on the basis of the internal and external forces are accumulated through a linear test in the water tank, And storing the look-up table in a database. The internal and external forces are measured using a time-of-flight method in actual navigation of the offshore structure 100 and stored in the database A third step of comparing the measured data of the internal and external forces of the second stage with the data of the internal and external forces accumulated in the look-up table of the first stage to predict data of the response of the offshore structure, And a fourth step of controlling in real time the posture or navigation route of the offshore structure using data on the response of the offshore structure , Fuel economy, safety operation and maintenance information provision through predictive monitoring and predictive control of external forces, hull stress, 6 degrees of freedom motion and location in real-time offshore structures.
