Abstract

The invention discloses an intelligent floating structure mooring and cable breaking experiment simulation method, which comprises an intelligent cable breaking device, an experimental model, mooringcables and an intelligent control and monitoring system, and is characterized in that a complete mooring experiment and a cable breaking experiment are carried out according to the experiment scheme,the intelligent cable breaking device is controlled through the intelligent control and monitoring system so as to control the mooring cables to be broken, dynamic responses of the experimental modelbefore cable breaking, at the moment of cable breaking and after cable breaking are monitored in real time through the intelligent control and monitoring system, dynamic responses of each mooring cable at different moments are monitored in real time, and displacement time-course data and acceleration time-course data of the experimental model and tension time-course data of the mooring cables aremonitored; and the experimental scheme is adjusted, and experiments of different experimental schemes are carried out. According to the invention, the cable breaking control of the floating mooring structure under the experimental condition is simulated, the transient dynamic response of the floating body and the dynamic characteristics of the mooring cable can be accurately simulated when the mooring cable is broken, and the problem of cable breaking transient control and monitoring under the experimental condition is solved.

Description

technical field [0001] The invention relates to the analysis and experiment technology of marine floating structure mooring, in particular to an intelligent floating structure mooring and cable breaking experiment simulation method. Background technique [0002] When the floating structure is engaged in production activities in the operating sea area, its position and direction are generally maintained by the mooring system. As a permanently moored floating structure, the floating foundation and its mooring system must not only withstand mild sea conditions during its life cycle, but also inevitably encounter various sea conditions, fatigue, corrosion, etc. Mooring lines may break, which could affect the safety of the structure. [0003] In the design stage of marine floating structures, it is one of the necessary links to consider the damage analysis of the mooring system, and it is also one of the key elements that have an important impact on the safety of the entire syst...
