N2 - Long-term operation of mooring systems is one of the challenging issues of floating structures such as floating offshore wind turbines. The nondestructive testing and condition monitoring techniques can achieve a rational operation by predicting the degradation. However, as contrasted with fatigue only few studies on the effect of nonuniform volume loss of mooring chain links due to wear can be found because of difficulties to estimate wear amounts quantitatively. This chapter introduces the quantitative interlink wear estimation method by applying it to a spar-type floating structure and utilizing the observations. The method is presented which consists of the material test, derivation of an interlink wear estimation formula with Finite element analysis, and calculation of mooring chain response with coupled dynamic analysis. Additionally, by using a 3-D rigid-body link model, it was found that the interlink wear amount can be calculated closer to the chain diameter measurements.
