A method for installation of a pile adapted to support an offshore wind turbine, wave-induced motion compensated pile holding system, vessel, and pile holder.

摘要

The invention relates to a method for installation of a pile adapted to support an offshore wind turbine in which the piles are transported horizontally, positioned in a pile holder, rotated to a vertical orientation while being held by the pile holder, and subsequently lowered into the water while being held by the pile holder, wherein the installation vessel is in a floating condition, and wherein the pile holder is compensated for wave-induced motion of the vessel to maintain a predetermined X-Y location independent of the wave-induced motion of the vessel. The invention also relates to a pile holding system, a pile holder, and a vessel comprising a pile holding system.
