Structural analysis of pile-foundation offshore platform

Abstract

This paper takes the pile-foundation platform of Dagang Oilfield in paralic zones as the research object, provides a reference basis for further selection by analyzing the advantages and disadvantages of single platform type and multi-platform type. The key structural parameters including platform load calculation, deck bottom elevation determination and ultimate bearing capacity calculation of pressurized piles are analyzed and studied. The specific ideas of pile-foundation platform design are proposed, and the analysis process and important formulas of the methods used in the design are elaborated to give the research results, which has high reference significance for the old platform to extend its service life and the construction of the new platform.
