To upend and lift an object, e.g. a foundation member of an offshore wind turbine, e.g. a monopole, use is made of an upending and lifting tool, wherein, with the tool suspended from one or more hoisting cables, e.g. from a crane hook of a crane, and with the frame of the tool initially in vertical orientation, a routine is performed which includes operating one or more shifting actuators, thereby moving a cable shifting member and engaging a cable engagement surface with the one or more hoisting cables at a height above a pivot axis. Further continuing this motion of the cable shifting member and thereby applying a cable shifting force on the one or more hoisting cables results, in reaction, in a pivoting of the frame into the horizontal orientation thereof.
