The mono pile support structure is a relatively simple design by which the tower is supported by the monopile, either directly or through a
transition piece. The mono pile continues down into the seabed. The structure is made of a cylindrical steel tube.The pile penetration depth is adjustable to suit the actual environmental and seabed conditions. A limiting condition of this type of support structure is the overall deflection (lateral movement along the monopile) and vibration, and are subjected to large cyclic, lateral loads and bending moments (due to the current and wave loads) in addition to axial loads (e.g. vertical loads due to the transition piece). Monopiles are currently the most commonly used foundation in the offshore wind market due to their ease of installation in shallow to medium water depths. This type of structure is well suited for sites with water depth ranging from 0-30m.
