Study on the Horizontal Movement State of Suction Anchor Piles for Offshore Wind Power during Horizontal Pulling

The subsea anchor piles of offshore wind power floating platform structures are mainly subjected to uplift and horizontal loads, this paper focuses on the case loads. A three-dimensional numerical simulation study pullout characteristics suction in clay layers was carried out reveal movement state during pile pullout, range depth at point where is achieved (referred as range), relationship between load ultimate movement, optimal location for movement. results show that certain pull-out points, produces an overall under suitable middle lower part pile, i.e. 14.2 m 14.5 m. 24,000 kN a within 14.2m maximum load; optimum 0.275 L (L length). For each existed it found two values were not exactly same, compared value load/horizontal tended 1.
