SYSTEM AND METHOD FOR PROVIDING INFORMATION ON FUEL SAVINGS, SAFE OPERATION, AND MAINTENANCE BY REAL-TIME PREDICTIVE MONITORING AND PREDICTIVE CONTROLLING OF AERODYNAMIC AND HYDRODYNAMIC ENVIRONMENTAL INTERNAL/EXTERNAL FORCES, HULL STRESSES, MOTION WITH SIX DEGREES OF FREEDOM, AND THE LOCATION OF MARINE STRUCTURE

There is disclosed a method for monitoring or controlling an operation of a marine structure, the method comprising: (1) measuring, by one or more inertial measurement units, 6-dof motion data of a marine structure indicative of an internal or external force applied to the marine structure in an actual voyage of the marine structure, and storing, by a computer, measured 6-dof motion data obtained from said one or more inertial measurement units in a database, wherein said one or more inertial measurement units includes at least one of a gyroscope or a fiber bragg grating; (2) accumulating, by the computer, data about a response of the marine structure according to the internal or external force, generating by the computer, a look-up table based on the accumulated data, and storing, by the computer, the look-up table in the database; (3) generating, by the computer, predictive response of the marine structure to the internal or external force applied to the marine structure based on a comparison of the measured data of the internal or external force applied to the marine structure obtained in the step (1) with the accumulated data about the internal or external force applied to the marine structure obtained in the step (2); (4) controlling, by the computer, a posture or reaction of the marine structure in real time according to the response of the marine structure to the internal or external force applied to the marine structure; (5) measuring stress on the marine structure following the operation of said one or more controllers in the step (4); and (6) adjusting the data in the look-up table for further reduction of stress on the marine structure.
