System and method for fuel savings and safe operation of marine structure

A method for controlling an operation of a marine structure, the method comprising:

• (1) accumulating, by a computer, data about an internal or external force applied to the marine structure by a fluid flow out of the marine structure by means of a linear test in a water tank or a wind tunnel, 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 a database;
• (2) measuring, by one or more sensors, the internal or external force applied to the marine structure by using a time-of-flight method in an actual voyage of the marine structure and storing, by the computer, information relating to the internal or external force applied to the marine structure in the database;
• (3) generating, by the computer, a predicted 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 (2) with the accumulated data about the internal or external force applied to the marine structure obtained in the step (1);
• and
• (4) controlling, by the computer, a posture or navigation path of the marine structure in real time according to the predicted response of the marine structure to the internal or external force applied to the marine structure.
