Large floating crane applies to the installation of steel structure of offshore lighthouse usually. But the steel structure is installed by using piling ship in order to reduce the construction cost and speed up the progress in the project. The lifting process is optimized by adopting universal lifting eyes, leading frames and the finite element software (Autodesk Robot). The technology is of good effect and applicable for similar projects.%外海灯塔钢结构通常采用大型起重船安装,为节约成本,加快安装进度,本工程钢结构采用了打桩船进行安装,通过采用万向吊耳、底板导向架、Autodesk Robot有限元软件优化了安装工艺等方面,使得此工艺顺利实施,且效果很好,值得在类似工程中推广运用.
