The invention relates to a ship chimney and superstructure integral hoisting method, which comprises the following steps of: calculating the integral weight gravity center after the ship chimney and superstructure are assembled according to the characteristics and the construction mode of the ship chimney and superstructure; a combined lifting lug and a mounting position are designed according to the weight center of gravity of the chimney and the superstructure; local thickening treatment is conducted on the deck provided with the combined lifting lugs and the longitudinal wall plates; a combined lifting lug anti-inclination toggle plate and a reinforcing toggle plate are designed; the combined lifting lugs are welded without defects to ensure that the lifting strength meets the requirement; after the chimney and superstructure hoisting scheme design is completed, finite element calculation is conducted on the chimney and superstructure hoisting scheme, and it is ensured that the maximum stress of all areas meets the design requirement during hoisting; and after the steps are completed, the ship body structure in the lifting lug area is optimized in advance, and actual lifting is conducted. The method has the characteristics of high hoisting efficiency, convenience and simplicity in operation and high universality.

    一种船舶烟囱及上建整体吊装方法,步骤:根据船舶烟囱及上建结构特点和建造方式,计算其总组后的整体重量重心;根据烟囱及上建的重量重心,设计组合吊耳及安装位置;对安装组合吊耳的甲板及纵壁板进行局部加厚处理;设计组合吊耳防倾肘板和加强肘板;无缺陷焊接组合吊耳,确保吊装强度满足要求;烟囱及上建吊装方案设计完成后,对其进行有限元计算,确保吊装时各区域的最大应力符合设计要求;完成以上步骤对吊耳区域船体结构的提前优化后,进行实际吊装。该方法具有吊装效率高、操作方便简单、通用性强的特点。
