This example considers the analysis of an eight-line mooring system. The analysis is performed in two phases. In the first, the moored vessel is explicitly included in the model, and is subjected to wind, wave and current loads in order to calculate the second order vessel motions in surge, sway and yaw. In the second phase, the computed second order motions are combined with high frequency vessel motions to simulate the combined vessel response. A reduced model is analysed in this second phase; the moored vessel is no longer explicitly included, and the response of only the most critical mooring line – that is, the one experiencing the greatest tension in the first phase - is examined.
This example illustrates the use of Flexcom in analysing mooring systems, with particular reference to the program ‘moored vessel’ capability. A detailed discussion of this facility is provided in Coupled Analysis.
The vessel and mooring system is shown in the below figure.
