It is important to estimate dynamic tension of the mooring line for design of floating artificial reef as the magnitude of the dynamic tension is the same order or so as that of the static tension. In this paper, we explain a simple calculation method for mooring line tension of floating artificial reef by current and wave, and compare the calculated results with the experimental results of Koterayama's experiment and experiments on two types of mooring lines in order to test sure the precision of the method, Moreover, we make it clear that variations of horizontal component of the dynamic tension at the lower end of mooring line became larger than that at the upper end of mooring line in some conditions.
