上层建筑整体吊装方案设计

随着船厂造船设备的不断更新,起重能力不断提高,使得现在的上层建筑分段越来越大,意味着上层建筑的重量也在不断提高,许多船厂都采用了整体吊装的手段进行上层建筑的吊装。上层建筑重量的提高,虽能够用起重能力的提升来解决,但起吊后会对本身产生更大的变形。本文主要围绕某典型船体上层建筑的整体吊装展开研究,确定了该船体上层建筑整体吊装方案,有效控制了变形。

The Scheme Designing for Integral Lifting of Superstructure

With constant updating of equipment in shipbuilding plants and continuous increasing of the hoisting capability,the superstructure segment becomes more and more big,which means the superstructure weight is also rising.Many shipyards have adopted the integral hoisting method for superstructure lifting.Although the increase of superstructure weight can be solved by improving the lifting capability,large deformation of the superstructure itself will be produced.This essay focuses on the integral hoisting of a typical ship superstructure,determines the integral lifting program,which effectively controls the deformation.
