浮式平台预警参数选取及阈值实时确定

Key Parameter Selection and Threshold Determination for Early Warning System of Floating Platform

基于浮式平台生命周期内潜在的风险,选取预警参数并建立预警阈值。以某深水浮式平台为例,在详细的数值分析基础上,研究与平台总体性能相关的预警关键参数的选取和预警阈值实时确定的算法及其实现。与传统的固定阈值法相比,预警阈值实时确定的算法可有效避免预警误报和漏报情况发生。

Based on the potential risks in the life cycle of the floating platform,the early warning parameters are selected and the early warning threshold is determined.Using a deep-water floating platform as an example,based on the detailed numerical analysis,the selection of the key parameters of early warning related to the overall performance of the platform and the algorithm and implementation of real-time determination of the early warning threshold are studied.Comparing to the traditional fixed threshold method,the real-time threshold method can minimize the occurrence of false alerts and missing alerts.
