The invention relates to the technical field of ship equipment installation, and discloses an FPSO (floating production storage and offloading) moon pool structure building method, which comprises the manufacturing of a moon pool lower cylinder, and comprises the following steps: 1, marking and positioning the lower cylinder and an upper cylinder, and arranging a jig I; 2, inversely manufacturing a lower cylinder body; 3, sand blasting; 4, scribing and positioning the lower sliding ring and arranging a jig frame; 5, assembling the lower sliding ring and the lower cylinder body; 6, turning over and hoisting; an upper lifting lug is welded to the position, corresponding to the lower barrel, of the lower sliding ring, and hoisting and overturning are conducted to enter a total assembly jig frame; 7, assembling the lower sliding ring and the upper cylinder body; and 8, checking after assembly. The manufacturing method of the moon pool upper cylinder comprises the following steps: 1, processing the arc plate sheets; 2, drawing a cross curve and arranging a jig frame; 3, normal manufacturing of a lower cylinder; 4, inspection and sand blasting; 5, cylinder body pre-assembly marking is carried out; 6, positioning the lower cylinder body; and 7, positioning the middle cylinder. Thermal stress and deformation in the welding process are reduced, the quality and strength of welding seams are ensured, and the building flexibility is high.
