中文摘要：

为解决传统方法制造大型海工装备周期长,对船坞要求高,下水困难的问题,提出了浮态制造方法。浮态制造方法是以水的浮力为支撑在水面上以分层制造,逐层叠加的方式直接制造产品的新方法,主要应用于大型海工装备的合拢装配。介绍了浮态制造基本原理和制造规范,并以浮态制造方法指导了SEVAN 650的建造,包括平台选择,分段划分及底层水下旋转。SEVAN 650的成功建造验证了浮态制造方法的可行性,可以解决大型海工装备下水难的问题,缩短制造周期。

英文摘要：

In order to solve the problem that the building of large marine engineering equipment in traditional method has a long manufacturing period,and a high requirement to dock and the difficulties in launching,it proposes the method of floating shipbuild.The floating shipbuild is a new method that is supported by the buoyancy of the water and that manufacture products directly in the way of layered manufacturing and layer-by-layer accumulation on the surface of water.It is mainly applied to assembly the large marine engineering equipment.It introduces the basic principles and manufacturing specifications of floating shipbuild,which has guided the manufacturing of SEVAN 650,including choice of platform,division of sections and underwater rotating of bottom.The success of SEVAN 650 verifies the feasibility of floating shipbuild,which can solve the difficulties of large marine engineering equipment launching and shorten manufacturing period.
