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

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

• (1) measuring, by one or more time and location information acquisition tools, an internal or external force applied to the marine structure in an actual voyage of the marine structure and storing, by a computer, measured data obtained from said one or more time and location information acquisition tools indicative of the internal or external force applied to the marine structure in a database, said measured data indicative of the internal or external force applied to the marine structure stored in the database includes time and location information;
• (2) accumulating, by the computer, data about 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) operating one or more controllers of the marine structure to control a posture, navigation path or reaction 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;
• (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.

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

• (1) periodically obtaining, by one or more sensors, environmental force data representative of internal or external force applied to a marine structure, obtaining response data representative of a predictive response of the marine structure due to the internal or external force applied to the marine structure, and storing, by a computer, said obtained environmental force data and said obtained response data in a database, wherein said environmental force data representative of the internal or external force applied to the marine structure includes natural frequency or harmonic frequency information;
• (2) generating, by the computer, a look-up table containing said periodically obtained environmental force data and said periodically obtained response data, and storing, by the computer, the look-up table in the database;
• (3) determining, by the computer, one or more operation parameters for operating one or more controllers of the marine structure to counteract against the internal or external force applied to the marine structure, said one or more operation parameters are determined based on a response data of the look-up table that corresponds to presently measured environmental force data;
• (4) operating said one or more controllers of the marine structure to control, by the computer, a posture, navigation path or reaction of the marine structure in real time according to the one or more operation parameters determined in the step (3) to reduce natural frequency or harmonic frequency due 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 respective response data and said one or more operation parameters for further reduction of stress on the marine structure.

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

• (1) obtaining environmental force data, which is representative of internal or external force applied to a marine structure, via one or more sensors;
• (2) querying a database storing a set of prestored response data and identifying response data that corresponds to the obtained environmental force data, wherein said response data identified from the database being representative of at least one predictive response characteristic of the marine structure resulting from the internal or external force applied to the marine structure;
• (3) based on the identified response data, determining one or more operation parameters for operating one or more controllers provided in the marine structure and operating said one or more controllers of the marine structure to control the marine structure to reduce stress on the marine structure by the internal or external force applied to the marine structure;
• (4) measuring stress on the marine structure following the operation of said one or more controllers according to the determined one or more operation parameters;
• and
• (5) adjusting the respective response data corresponding to the obtained environmental force data and updating the database with the adjusted response data.
