According to an aspect of the invention there is provided a reconfigurable mould assembly for the manufacture of wind turbine blades having different geometries. The mould assembly comprises a mould skin extending longitudinally in a spanwise direction and transversely in a chordwise direction. The mould skin defines a mould surface shaped to form a half shell of a wind turbine blade. The mould skin comprises a plurality of spanwise sections for arrangement end to end in a spanwise direction to form the half shell. The plurality of skin sections include one or more inboard skin sections for forming a root end of the half shell, and one or more outboard skin sections for forming a tip end of the half shell. The mould assembly further comprises a main frame comprising a series of independent main frame modules arranged end to end in the spanwise direction. The main frame modules include one or more inboard main frame modules for supporting the one or more inboard skin sections and one or more outboard main frame modules for supporting the one or more outboard skin sections. The mould assembly further comprises an intermediate support structure attached to a reverse side of each mould skin section. The intermediate support structure(s) attached to the inboard skin section(s) are releasably connectable to the inboard main frame module(s). The intermediate support structure(s) attached to the outboard skin section(s) are releasably connectable to the outboard main frame module(s).
