OFFSHORE VESSEL, PREFERABLY AN OFFSHORE WIND TURBINE INSTALLATION VESSEL, A CRANE FOR PROVIDING SUCH A VESSEL, AND A METHOD FOR USING SUCH A CRANE, PREFERABLY FOR UPENDING A MONOPILE
An offshore wind turbine installation vessel includes a crane provided with a computerized crane control system. The computerized crane control system is linked to the slew drive, the luffing drive, and the hoisting winch of the crane, and is programmed to perform a foundation pile installation routine providing a coordinated pattern of slew motion of the superstructure and of luffing motion of the boom structure, as well as operation of the hoisting winch so that the load connector of the crane moves from a foundation pile pick up position thereof, where the load connector is connected to the top end of a horizontally oriented foundation pile stored on a storage deck, to a foundation pile overhoarding position thereof, wherein the foundation pile is in vertical suspended from the load connector, outside of the hull.
