Installation of a monopile adapted to support an offshore wind turbine is done using a vessel comprising a hull, a crane mounted on the hull, and a motion compensating integrated pile upending and holding device. The device comprises a motion compensating support assembly mounted to the hull of the vessel and a pile holder that is supported by the support assembly and is tiltable about horizontal tilt axis relative to the support assembly between a horizontal orientation and a vertical orientation. The device allows for upending of the monopile by means of the crane of the vessel whilst the lower end portion remains received and supported by the pile holder. During at least a phase of the upending of the monopile, one or more of the controllable motion actuators of the motion compensating support assembly are operated to provide controlled motion of the lower end portion of the monopile so as to reduce swing motion of the monopile.
