[0002] Global demand for green energy has driven the export demand for wind power equipment. As a key component of wind power equipment, wind turbine towers are typically quite large. How to store wind turbine towers and how to transport them safely and economically over oceans have become issues that need to be addressed.

[0003] Current technologies for storing and transporting wind turbine towers at sea typically involve laying the towers flat in warehouses, docks, or on ship decks. This is because wind turbine towers are quite tall, making it difficult to vertically fix them, especially stably on ship decks. The disadvantages of horizontal storage and transportation of wind turbine towers include large storage space requirements and low transportation efficiency, significantly increasing the economic costs and carbon emissions of tower transportation, which contradicts the core values ​​of a green economy. Prolonged horizontal placement can also easily cause excessive ellipticity in the tower cross-section and lead to damage to the base of the horizontally transported tower due to metal fatigue.
