Embodiment 1

[0014] This embodiment provides a high-strength steel assembled ship moon pool assembly process, which is characterized in that: the high-strength steel assembled ship moon pool assembly process includes the following steps:

[0015] The concave moon pool is processed on the concave tire frame,

[0016] The convex moon pool is processed on the convex tire frame,

[0017] The concave moon pool and the convex moon pool are combined to form the moon pool.

[0018] The whole moon pool is hoisted and placed on the hull.

[0019] The concave tire frame and the convex tire frame adopt an integrally formed groove surface, and the grooves of the concave tire frame and the convex tire frame are perpendicular to any adjacent two surfaces of the convex groove.

[0020] The moon pool is made of high-strength steel.

Abstract

A high-strength steel assembled ship moon pool assembly technology is characterized by comprising the following steps that a concave moon pool is machined and completed on a concave bed-jig, a convexmoon pool is machined and completed on a convex bed-jig, the concave moon pool and the convex moon pool are folded to form the moon pool, the whole moon pool is hoisted and arranged on a ship, the concave bed-jig and the convex bed-jig adopt integrally formed groove faces, any two adjacent faces of a concave groove of the concave bed-jig and a convex groove of the convex bed-jig are perpendicularto each other, and the moon pool adopts high-strength steel. The high-strength steel assembled ship moon pool assembly technology has the advantages that a separated manufacturing manner is adopted, the moon pool is manufactured away from a platform, deformation, caused by internal stress of a large steel structure of the platform, of the moon pool is avoided, and meanwhile the whole precision control of the moon pool is guaranteed through segmented control over the moon pool components.

Description

technical field [0001] The invention relates to the technical field of ship manufacturing, and in particular provides a high-strength steel assembled ship moon pool assembly process. 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. 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 [0003] The purpose of the...
