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

A method for fuel savings and safe operation by real-time predictive monitoring and predictive controlling of aerodynamic environmental internal or external force, hull stresses, 6 degrees of freedom (6-dof) movement and location of a marine structure, the method comprising:

• (1) accumulating data about an internal or external force applied to a marine structure by a gas flow out of the marine structure by means of a linear test in a water tank or a wind tunnel and data about a response of the marine structure according to the internal or external force to generate a look-up table, and storing the look-up table in a database;
• (2) measuring the internal or external force by using a time-of-flight method in an actual voyage of the marine structure and storing the internal or external force in the database;
• (3) comparing the measurement data of the internal or external force obtained in the step (2) with the data about the internal or external force accumulated in the look-up table in the step (1) to predict data about a response of the marine structure;
• and
• (4) controlling a posture or navigation path of the marine structure in real time by using the predicted data about a response of the marine structure.
