Modular System for Transporting Wind Turbine Blades

A transport system for transporting wind turbine blades in at least two different spatial arrangements, each blade having a tip end and a root end, each blade further having a bolt circle diameter D at said root end, the system comprising:

• two or more root end transport frames each having a height H for supporting a root end of a wind turbine blade, wherein H<D;
• two or more extendible tip end transport frames for supporting a portion of a wind turbine blade towards the tip end of said blade, each extendible tip end transport frame comprising a base frame, at least one vertical extension means for extending the height of the tip end transport frame and a support bracket provided on top of said base frame for receiving a portion of a wind turbine blade;
• wherein each extendible tip end transport frame is stackable on top of a root end transport frame and vice versa, such that the modular system is operable to stack successive wind turbine blades in an alternating root end to tip end arrangement with at least two alternative inter-blade spacings created by varying the height of the extendible tip end transport frames via the vertical extension means.
