AI Technical Summary

Technical Problem

In the existing technology, the virtual operating system of the offshore lifting platform cannot accurately simulate the changes in the pile leg load under different operating conditions, resulting in inconsistency between the simulated operation process and the actual operation, affecting the training effect.

Method used

By acquiring the working conditions of the virtual model, the draft of the offshore platform, and the relative displacement between the pile legs and the platform in real time, a specific formula is used to calculate the load on each pile leg, including the load changes under working conditions such as pile leg raising, lowering, pile insertion, platform raising, pre-loading, platform lowering, and pile extraction.

Benefits of technology

A high degree of consistency is achieved between the pile leg load data and the actual platform operation process, which improves the realism of the simulation operation and the training effect, enabling operators to better master the full process operation of the lifting platform.

Abstract

A method for simulating pile leg loads in a virtual operating system for a lifting platform, wherein the control object of the virtual operating system for the lifting platform is a virtual model of an offshore lifting platform, which includes the offshore platform and four pile legs that can move up and down relative to the offshore platform. The method for simulating pile leg loads includes: obtaining the working conditions of the virtual model and the relative displacement between each pile leg in the virtual model and the offshore platform in real time; and calculating the load of each pile leg in real time based on the obtained working conditions of the virtual model and the relative displacement between each pile leg in the virtual model and the offshore platform. This design distinguishes different working conditions and uses different calculation methods to calculate the load of each pile leg under different working conditions. This allows the pile leg loads of an offshore lifting platform to be simulated in virtual operations, and the simulated pile leg loads are basically consistent with the data changes of the pile leg load sensors during actual platform operation.
