Construction method for ocean platform

Abstract

The invention discloses a construction method for an ocean platform. The method comprises the following steps of: constructing an upper ship body and a lower ship body; launching the upper ship body and the lower ship body; folding the upper ship body and the lower ship body; and performing outside fitting-out. The upper and lower ship body folding process comprises the following steps of: dragging launched upper and lower ship bodies to a dockyard specified position; hoisting the upper ship body to a certain height position; positioning the lower ship body below the upper ship body; and folding the upper ship body and the lower ship body into a whole in a butt joint mode. By the method, the construction period of the ocean platform can be shortened, and labor cost can be saved; and the method is not limited by surges, and is short in folding time and high in folding accuracy.

Description

technical field [0001] The invention relates to the field of ocean engineering and shipbuilding, in particular to a method for building an ocean platform that can independently manufacture the upper hull and the lower hull of the ocean platform, and then integrally assemble the main hull through launching and hoisting. Background technique [0002] At present, there are problems in the traditional offshore platform construction process such as long time-consuming, labor-intensive, and high-altitude operations. There are mainly two traditional offshore platform construction methods: [0003] One is land construction, which mainly follows the method of building the main hull layer by layer from the lower hull to the upper hull, and then sends the main hull into the water through a certain mechanical launching method, and then drags the main hull to the outfitting wharf by tugboats Complete the external outfitting work, and finally complete the system commissioning and deliver ...

AI Technical Summary

Problems solved by technology

[0008] In view of the above problems, the present invention provides a method for constructing an offshore platform, which allows the upper hull (deck box) and lower hull (lower hull) of the offshore platform to be independently constructed, so as to solve the long construction period required for the traditional method of constructing the offshore platform. Occupy the dock for a long time, expensive and other problems; and solve the problems of foreign countries using barges and ballast water to build offshore platforms that require high water depth and sea surface calmness, and the size of barges and load limit the size of the platform
