... analysis is performed to evaluate parameters such as maximum line tensions, angular and linear displacements that can occur under various external conditions. The maximum values of these parameters must be less than the permissible ones to ensure the safety of the structure. The efficiency of the platform...

... platform. Under the different water depth of 100m, 150m, 200m, the time domain motion response calculation model of floating wind turbine platform was established, and the corresponding time-domain motion of wind turbine platform with six degrees of freedom and the mooring line tension were analyzed...

... AND MULTIPARAMETER PROBLEM (SURVIVAL MODE) The main hazard for a structure functioning in survival mode is breaking of the lines. That is why, the margin, determined by the ratio of the current line tension to breaking force, can be taken as a criterion ratio. 69 It is assumed that a matrix of design cases has been...
