Abstract: A method of manufacturing a shell (36 and 38) of a wind turbine blade (10) is disclosed. The method comprises providing a mould (9) having a marker (11) at pre-determined locations. One or more layers of fiber fabrics are provided on surface of the mould (9) to form a shell half structure (36 and 38). Resin is infused through the one or more layers of fiber fabrics and subsequently cured to obtain the shell half structure (36 and 38). A reference portion (19) is marked on the shell half structure (36 and 38) to assemble one or more components on the shell half structure (36 and 38), by detecting a location of the marker (11) in the mould (9) by a detection device (13). The above method facilitates accurate positioning of component such as shear webs (7).
