System and method for static and dynamic positioning or motion control of offshore structures

摘要

The present invention relates to a system and method for static and dynamic positioning or motion control of offshore structures. More particularly, the present invention reflects offshore environmental forces and fluids in offshore structures and risers and mooring lines. Real-time monitoring of periodic or non-periodic complex energy and response due to mechanical or aerodynamic properties and based on this, optimal static and dynamic positioning or motion control for offshore structures The present invention relates to static and dynamic positioning or motion control systems and methods for offshore structures utilizing real-time monitoring of featured mooring lines. The present invention avoids the critical point of the mooring line by accurately predicting the life of the mooring line through static and dynamic real-time monitoring of the mooring line, and extends its service life in general. Therefore, a lot of cost is required to periodically perform ROV underwater inspection on the mooring line. However, according to the present invention, since the real time monitoring is performed on the mooring line, the cost required for underwater inspection is reduced. You can save.
