CONTROL METHOD THROUGH ACTUAL TIME MONITORING OF PHYSICAL CHANGE TO MARINE STRUCTURE, AND FUEL REDUCTION SAFETY OPERATION METHOD, MAINTENANCE INFORMATION PROVIDING METHOD AND CONTROL METHOD THROUGH PERFORMING PREDICTION MONITORING OR PREDICTION CONTROL OF EXTERNAL FORCE, HULL STRESS, SIX-DEGREE-OF-FREEDOM OF MOTION AND POSITION IN GASDYNAMIC OR HYDRODYNAMIC ENVIRONMENT TO REAL TIME MARINE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a fuel reduction method in a marine structure part for monitoring physical change of external force, hull stress, six-degree-of-freedom of motion and position, or the like in a gas or hydrodynamic environment to a marine structure to control the marine structure in real time.SOLUTION: By at least one or more optical sensor type measurement method using an optical fiber bragg grating, physical change of a marine structure is accurately monitored in real time, and external force, hull stress, six-degree-of-freedom of motion and position in a gas or hydrodynamic environment to the marine structure undergoes prediction monitoring and control in real time. More in detail, changes in front/rear and right/left inclinations, draft, trim, corrosion, erosion, cracking, pressure, vibration, frequency, or the like applied to a marine floating matter by external force in gas or hydrodynamic environment are comprehensively measured, and the marine structure undergoes prediction control on the basis of the measurement to provide fuel reduction, safety operation and maintenance information.SELECTED DRAWING: Figure 6
