.... This tension reading is understood to be an under prediction of the tension experienced at the fairlead due to Coulomb friction between the chain and the fairlead roller (Tahar et al., 2005). Dynamic tension is especially affected by this phenomenon, and it was found that the dynamic friction would act...

... modeling of the dynamic response of the floating breakwater. Secondly, it calculates the static and dynamic tension; the maximum tension that is exercised on each mooring line determines the failure or not of the mooring lines. The geometry of a typical mooring line is shown in Fig. 2. The static analysis...
