.... 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...
