The invention discloses a novel Spar type fan complete machine floating transportation method. The method comprises the following main technological processes that: dividing a Spar type fan foundation into an upper part and a lower part which are connected through a connecting shaft, prefabricating the Spar type fan foundation on land, and then hoisting the foundation into a transportation installation ship with a frame body structure to be fixed; sequentially hoisting a tower drum, a machine head and blades; transporting to a specified installation site, and centralizing the lower foundation and locking the connecting shaft by using an automatic ballasting system; connecting the lower foundation with the anchoring foundation through a mooring system; and completing the installation of the whole fan, and enabling the transportation installation ship to exit from the installation site. The whole machine transportation of the Spar type draught fan can be achieved, large-scale offshore restarting and hoisting equipment does not need to be used for offshore operation, and the offshore installation cost is reduced; and in addition, compared with a traditional offshore floating type fan split installation technology, the method shortens the offshore operation time, and solves the problems that offshore construction is difficult, safety is low, and the operation window period is short.

    本发明公开了一种新型Spar式风机整机浮运方法,其主要工艺流程是Spar式风机基础分为由连接轴连接的上、下两部分,在陆上预制完成后吊装入带有框体结构的运输安装船并固定;依次吊装塔筒、机头、叶片;运输至指定安装场地,利用自动压载系统扶正下部基础并锁死连接轴;采用系泊系统将下部基础与锚固基础连接;风机整机安装完成,运输安装船退出安装场地。本发明可以实现Spar式风机的整机运输,不需要使用大型海上启重、吊装设备进行海上作业,减少了海上安装成本;另外,相比于传统海上浮式风机分体安装工艺,该方法减少海上作业时间,解决了海上施工难度大、安全性低以及作业窗口期短等问题。
