Embodiment Construction

[0033] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0034] This embodiment is illustrated with the SEVAN650 cylindrical ultra-deep sea drilling platform. The maximum diameter of the cylinder of this offshore drilling platform is 85 meters, the molded width is 75 meters, and the height of the main body will reach 135 meters. The method of segmental construction accuracy control includes the following steps:

[0035] First, build the platform model: based on experience and combined with the actual situation of the cylindrical ultra-deep sea drilling platform, add 0.1‰~0.35‰ shrinkage data; then load the added shrinkage data into the 3D design software TRIBON, and carry out platform data modeling;

Abstract

The invention relates to the technical field of marine engineering equipment and large-sized ship construction, in particular to a sectional construction precision control method for a cylindrical ultra-deep sea drilling platform. The method can be applied to sectional construction precision control of various sea drilling platforms and large-sized ships. The method comprises the following steps of: platform model construction, section of main hull manufacture, sectional construction process division and precision control of each process stage. The method can produce important influence on quality and construction efficiency of a hull in a maritime work product manufacturing process. The sectional construction precision control method reduces the operation time and shortens the construction period of the large-sized sea drilling platform by precision control of each subsection from baiting to completion, meanwhile reasonably reduces the quality loss and the construction cost, and realizes modularized regional shipbuilding.

Description

technical field [0001] The invention relates to the fields of ocean engineering and large-scale ship product manufacturing, in particular to a segmented construction accuracy control method of a cylindrical ultra-deep sea drilling platform. technical background [0002] Shipbuilding precision management is based on the hull construction precision standard as the basic criterion. Through scientific management methods and advanced technological means, the dimensional precision control of hull parts, sections and whole ship fittings is carried out to minimize the number of assembly operations on site. Shipbuilding precision control is closely related to production conditions: if the shipbuilding precision and tolerance standards are too high, it will often deviate from the actual conditions of factory equipment and personnel, which will prolong the production cycle and increase the product scrap rate; If it is low, the precision of the product will be poor, and each process req...
