In order to moor a floating offshore wind farm with a generator as large as 5000 kW, the cost of construction will be higher by using conventional anchors because of its small holding capacity. Therefore, a free fall tubular pile anchor has been developed which can be easily penetrated into clayey sea bed by dropping from a height above seabed. We conducted model test to evaluate the dynamic characteristics in water and soil by using the anchors with or without four sheets of fin to stabilize and increase the pullout capacity. This paper describes the comparison of analysis and measurement for the dynamic characteristics, along with the obtained friction and resistance factors in water and soil.
