The invention belongs to the technical field of shipbuilding, and discloses a method for manufacturing a moon pool of a ship. The method comprises the following steps of processing a first pool body, a second pool body, a third pool body and a fourth pool body on a moon pool mold; superposing the first and third pool bodies to form a first half-moon pool; superposing the second and fourth pool bodies to form a second half-moon pool; closing the first and second half-moon pools to form the moon pool; integrally lifting and arranging the moon pool on a ship body, wherein the moon pool mold comprises a convex mold and a concave mold, and the first, second, third and fourth pool bodies are corrected and shaped by the convex and concave molds. According to the method for manufacturing the moon pool of the ship, a separate manufacturing method is adopted, the moon pool is separated from a platform for manufacture, and the internal stress of a large steel structure of the platform is prevented from causing deformation of the moon pool; meanwhile, the integral accuracy control is ensured by sectionally controlling parts of the moon pool.
Description
technical field [0001] The invention relates to the technical field of ship manufacturing, in particular to a method for manufacturing a ship moon pool. Background technique [0002] In marine engineering, FPSO and other products, the moon pool area is often the structure with the highest precision requirements. Because it is located in the large opening area, it is a strong component, the plate is thicker, the welding quality is high, and the welding deformation is also large. In the current construction process, the moon pool is generally constructed in the form of segmented installation parts or pieces, and then the berth is assembled. [0003] The precision control point of this construction method lags behind, and it is difficult to control the precision of the final assembly when it is constructed with components or pieces. Correction is difficult due to the greater structural strength here. Contents of the invention [0004] The technical problem to be solved by t...
