Description
Technical Field
The invention belongs to the technical field of ship construction, and particularly relates to a multi-section continuous construction method for a straight area at the upper part of an engine room of an LNG ship.
Background
In the process of building the large-scale ship, the ship is mainly divided into a plurality of sections, then the sections are built, and after the sections are built, the sections are assembled. Because the manufacturing process of the segment building is more, the accumulated error between the segments is difficult to avoid. The accumulated errors can cause the increase of the construction cost and the lower construction efficiency, and mainly appear as the following three points:
firstly, accumulated errors cause secondary repair and cutting of a machined groove, a large amount of labor consumption and poor welding quality are caused, and the segmented machined groove is formed by a machine in a machining stage, so that the welding quality is easy to guarantee when the forming precision is good and welding is carried out. If the groove is formed twice, only manual cutting can be adopted, and the groove needs to be manually polished after cutting.
Secondly, accumulated errors cause secondary positioning of the total assembly and the carrying of the subsection, so that the consumption of crane resources and matched manpower and kinetic energy is caused, and the secondary positioning of the subsection refers to secondary positioning after the first positioning and the second positioning after the cutting due to the fact that the butt joint does not meet the requirements.
Thirdly, accumulated errors cause that the sectional outfitting cannot be preassembled before the assembly and the carrying, and crane resources are consumed and special process holes are formed for installation during subsequent installation.
As shown in fig. 1 and 2, the flat upper region of the LNG ship tank is constructed by dividing six sections, which are sequentially, in a clockwise direction, an EG01P section, an EG02P section, an EG03P section, an EG03S section, an EG02S section, and an EG01S section, and the relative positions of the six sections are as shown in fig. 1 and 2.
