Wind turbine rotor blade spacer, transportation and storage system for wind turbine rotor blades and related method

A transportation and storage system for wind turbine rotor blades having a longitudinal axis and comprising a root end and a tip, and two halves bonded together forming an outer shell, wherein the system comprises:

• a first blade and a second blade;
• at least two root frames including a first root frame and a second root frame, each one of the first root frame and the second root frame configured to support the root end of the first blade and the root end of the second blade respectively;
• at least two tip frames including a first tip frame and a second tip frame, each one of the first tip frame and the second tip frame configured to support the tip of the first blade and the tip of the second blade respectively;
• at least one rotor blade spacer comprising a guide being adapted to guide a second blade assembly comprising the second blade with respect to the first blade assembly comprising the first blade, wherein the at least one rotor blade spacer is configured to be joined to the first root frame and to the second root frame or to be joined to the first tip frame and to the second tip frame such that the first blade assembly comprising at least the first root frame, the first tip frame and the first wind turbine blade is joined to the second blade assembly comprising at least the second root frame, the second tip frame and the second wind turbine blade, and wherein the spacer is configured to join the second blade assembly to the first blade assembly establishing a separation between the first blade assembly and the second blade assembly;
• and
• wherein the first root frame and/or the second root frame comprise a first width, the first width measured in a direction perpendicular to the longitudinal axis of the first blade at a widest portion of the first root frame and/or the second root frame, respectively, and wherein the root end of the first blade and/or the second blade comprises a first diameter, wherein the first width is smaller than the first diameter.
