The invention relates to the technical field of floating type oil storage and unloading ships, and discloses a midship structure of a multifunctional floating type production storage and unloading device, which comprises a ship body top section, a ship body middle section, a ship body bilge section and a seawater lifting base pipe body. According to the midship structure of the multifunctional floating type production, storage and unloading device, the first lifting pipe, the second lifting pipe and the third lifting pipe are arranged, each seawater lifting base pipe body is divided into three lifting pipe pieces, the three lifting pipe pieces are machined and rolled in a one-piece mode to be formed, the butt joint ends are welded, and therefore the whole structure is formed. A first lifting pipe, a second lifting pipe and a third lifting pipe are formed respectively, then the first lifting pipe, the second lifting pipe and the third lifting pipe are placed on a jig frame to be in butt joint, then laser positioning is conducted, it is guaranteed that the concentricity of the first lifting pipe, the second lifting pipe and the third lifting pipe is accurate, and a complete seawater lifting base pipe body can be formed. The welding seam of the single lifting pipe is short, the welding precision is easy to control, and deformation of the pipe body of the seawater lifting base after welding is avoided.
本发明涉及浮式储卸油船技术领域,且公开了多功能浮式生产储卸装置的船中结构,包括:船体顶部分段、船体中部分段、船体舭部分段和海水提升基座管体。该多功能浮式生产储卸装置的船中结构,通过设置第一提升管、第二提升管和第三提升管,每根海水提升基座管体一共取三块提升管分片,三块提升管分片均一片式加工卷板成型,将对接端进行焊接,分别形成第一提升管、第二提升管和第三提升管,再将第一提升管、第二提升管和第三提升管放置在胎架上进行对接,然后进行激光定位,保证第一提升管、第二提升管和第三提升管的同心度准确,可组成完整的海水提升基座管体,单根提升管焊缝短,容易控制其焊接的精度,避免焊接后海水提升基座管体变形。
