Installation technology of offshore wind turbine generator

The invention relates to an installation technology of an offshore wind turbine generator. The technology comprises the following steps that a platform moving ship is positioned and jacked up, a positioning barge drops an anchor in place, a transporting barge is in place, a tower drum is turned over, blades are turned down, a fan tower drum is hoisted, a cabin hub is hoisted, and the blades are hoisted and installed; and the step of sequentially hoisting the fan tower drum comprises bottom-section tower drum hoisting, middle-section tower drum hoisting and upper-section tower drum hoisting. The technology has the advantages that the tower drum is installed and fixed in a segmented mode, rapid positioning is achieved, the hoisting stability and levelness of the tower drum are guaranteed, and rapid and accurate positioning of the blades is achieved. 本发明涉及一种海上风电机组的安装工艺，包括平台移船定位并顶升、定位驳船抛锚就位以及运输驳船就位、塔筒翻身和叶片倒驳、风机塔筒吊装、机舱轮毂吊装、叶片起吊安装，所述风机塔筒依次吊装包括底段塔筒吊装、中段塔筒吊装和上段塔筒吊装。本发明具有如下优点：通过对塔筒分段进行安装固定，实现快速定位，保证塔筒起吊的平稳性以及水平度，实现叶片的
