    Behavior of Monopile Foundations for Offshore Wind Farms

    Jan 01, 2016  Most offshore wind-turbine foundations are monopile foundations. Monopile foundations have the advantages of simple structures and are convenient to construct. In recent years, large-diameter monopile foundations, with diameters larger than 4 m, have been used in engineering applications to increase the bearing capacity of wind turbines.

    Bearing behavior of multiple piles for offshore wind

    Jan 01, 2017  The bearing behavior of a multiple-pile foundation should be different from that of a group-pile foundation because of the different pile spacing. Previous studies of multiple-pile foundation for offshore wind generators were limited and focused mainly on the behavior of the support structure, not that of the piles.

    Several foundation types are availe for wind energy offshore towers: gravity-type, monopile, jacket-pile, tripod and suction caissons. The type of foundation used depends mainly on water depth and sea bed conditions: there is no “standard” concrete foundation as in the onshore wind farms. The solution used more often is the monopile.
