摘要： Disclosed is a system and method for monitoring a physical change of a marine structure which includes a complex optical measuring instrument for detecting a behavior and structural change of the marine structure by using at least one optical sensor by means of optical fiber Bragg grating. A physical change of the marine structure may be accurately monitored in real time by introducing an optical sensor-type measurement method. Disclosed is real-time predictive monitoring and predictive controlling of aerodynamic and hydrodynamic environmental internal or external force, hull stresses, 6 degrees of freedom (6-dof) movement and location of a marine structure, and more particularly a method for synthetically measuring changes of four-directional slopes, sea gauge, trim, corrosion, erosion, crack, pressure, stress, vibration, frequency or the like applied to a floating marine structure by means of aerodynamic environmental internal or external force, and predictively controlling the marine structure based thereon to provide information on fuel savings, safe operation and maintenance. In an aspect, a method for providing information on fuel savings, safe operation and maintenance 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 includes (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.
