AI Technical Summary

Technical Problem

The construction of large-scale self-elevating wind power installation platforms in the existing technology cannot meet the delivery cycle requirements. Conventional methods result in a long waiting time for the main hull to be loaded and the pile shoes to be built.

Method used

The main hull and pile shoes are constructed simultaneously in the dock, the construction accuracy of the pile shoes and the surrounding shaft sections is controlled, the pile shoe loading data is simulated using software, the pier height is adjusted, and the precise pier seating of the main hull is achieved through precise water positioning and buoyancy adjustment.

Benefits of technology

The common construction period of the main hull and pile shoes is shortened, the construction efficiency of large-scale wind power installation platforms is improved, and the shipowner's delivery period requirements are met.

Abstract

The present invention relates to the field of shipbuilding technology, and discloses a method for positioning and piercing a self-elevating platform, comprising the following steps: S1, synchronously constructing the main hull and the pile shoe, controlling the construction accuracy of the main hull's well section and the pile shoe; S2, collecting the outer contour data of the pile shoe and the well center position data of the main hull's well section, using software to simulate the pile shoe loading data, and obtaining the loading positioning data of the pile shoe and the main hull during loading; S3, adjusting the pier height, determining the dock pier layout, and the pile shoe entering the dock and being placed according to the loading positioning data; S4, lifting and moving the main hull and adjusting its floating state; S5, after the main hull's floating state is leveled, the hull personnel perform water positioning of the main hull based on the loading positioning data, and pump water from the dock, so that the main hull is accurately pierced. By synchronously constructing, the common construction period of the main hull and the pile shoe is shortened, thereby improving the construction efficiency of the large-scale wind power installation platform and meeting the shipowner's delivery period.
