The invention relates to method of loading wind turbine components to a maritime vessel, the method comprising:
- preparing one or more wind turbine main components (11, 12, 13) in a back area (30) away from a quayside (31);
- placing a number of wind turbine main components (11, 12, 13) on an upper side (20) of a transport module (1);
- position at least two self-propelled modular transporters (SPMT's) (2) in tunnel-shaped grooves (22) in an underside (21) of the transport module (1); and
- lifting, from the ground the transport module (1) comprising the one or more wind turbine main components (11, 12, 13) by a number of SPMT's (2) and moving the transport module (1) from the back area (30) across the quayside (31) and onto a deck (8) of a feeder vessel (7) moored at the quayside (31).
The invention further relates to a transport module (1) configured for transport of wind turbine main components (11, 12, 13), the transport module (1) comprising an upper side (20) for supporting wind turbine main components (11, 12, 13), two parallel sides (23), two parallel ends (24) and an underside (21), in which underside (21) two and preferable three tunnel-shaped grooves (22) are formed.
