The invention discloses a construction and installation method of an FPSO upper module, and belongs to the technical field of FPSO construction, and the construction and installation method is characterized by comprising the following steps: S1, construction of a square buttress and the upper module; s2, the limiting support is welded; s3, mounting an elastic block in the horizontal direction; s5, mounting a vertical elastic block: mounting the vertical elastic block on the top surface of the square buttress; and S6, hoisting of the upper module, wherein the upper module is hoisted to the deck of the ship body through the floating crane ship, and the upper module is supported on the top faces of the square buttresses. The vertical elastic blocks and the horizontal elastic blocks are additionally arranged between the base and the square buttresses of the upper module, when the ship body is bent longitudinally, a certain amount of ship body bending deformation can be buffered through compression deformation of the elastic blocks, extra stress and deformation of the upper module caused by ship body deformation are reduced, and the ship body can be protected. And meanwhile, the vibration generated by the upper module is effectively blocked, and the technical effect of vibration reduction is achieved.
本发明公开了一种FPSO上部模块的建造安装方法,属于FPSO建造技术领域,其特征在于,包括以下步骤:S1、方形支墩和上部模块的建造;S2、限位支座的焊接;S3、水平方向弹性块的安装;S5、竖向弹性块的安装:将竖向弹性块安装在方形支墩的顶面上;S6、上部模块的吊装:利用浮吊船将上部模块吊装到船体甲板上,并将上部模块支撑在方形支墩的顶面上。本发明在上部模块的底座和方形支墩之间增设了竖向弹性块和水平方向弹性块,当船体发生总纵弯曲时,利用弹性块的压缩变形可以缓冲一定量的船体弯曲变形,降低上部模块因船体变形而产生的额外应力和变形,并同时有效阻隔了上部模块产生的振动问题,具有减振的技术效果。
