  • Publication number: 20220177081
    Abstract: A vessel and a method for installation of a pile adapted to support an offshore wind turbine are described. The method includes a) suspending the pile from a hoisting cable in a substantially vertical orientation; b) providing a lower end of the pile in a pile holding system limiting horizontal motion of a pile portion held by the pile holding system; and c) lowering the pile with the pile being held by the pile holding system. The lowering includes at least lowering the pile through a splash zone of a body of water, and during step c), two tugger lines are directly or indirectly connected to the pile at a location between the pile holding system and the hoisting cable, said tugger lines being operated to damp motion of the pile in two respective horizontal directions.
