METHOD AND SYSTEM FOR STATIC AND DYNAMIC POSITIONING OF MARINE STRUCTURE BY USING REAL-TIME MONITORING OF MOORING LINE

摘要

The present invention provides a system and a method for static and dynamic positioning of a marine structure by using real-time monitoring of a mooring line. In the present invention, static and dynamic real-time monitoring data of the mooring line is obtained and processed to control and maintain the positioning of the marine structure. According to the present invention, tension of the mooring line can be measured by the real-time monitoring of the mooring line, and the static and dynamic positioning of the marine structure can be appropriately and automatically controlled and maintained in accordance with the measurement. Also, life of usage of the mooring line can be extended by accurately predicting the life of the mooring line through static and dynamic real-time monitoring of the mooring line and by avoiding a critical point of the mooring line. In addition, periodic underwater ROV testing for the mooring line generally involves high cost, but according to the present invention, the cost for underwater testing can be reduced by the real-time monitoring of the mooring line.
