1. A method of performing at least one post-moulding operation on a spanwise blade segment (70) of a wind turbine blade, the blade segment (70) comprising a shell structure (82) with an open end (86) and a spar structure (62) arranged at least partly within the shell structure (82) and protruding from the open end (86), the method comprising the steps of:
providing a holding device (88) for supporting the blade segment (70) at the spar structure (62) thereof, the holding device (88) comprising a coupling member (90) for engaging the spar structure (62);
holding the blade segment (70) with the holding device (88) such that the spar structure (62) of the blade segment (70) is engaged by the coupling member (90); and
performing at least one post-moulding operation on the shell structure (82) of the blade segment (70), wherein the shell structure (82) is not directly engaged by the holding device (88), such that the shell structure (82) is freely accessible,
wherein the holding device (88) further comprises actuation means for rotating the coupling member (90) around a longitudinal axis (Lo) thereof, wherein the actuation means comprises a motor.
