거동 모니터링을 통한 해저 양광시스템의 피로수명 예측

Abstract

In this paper, methodology for predicting fatigue life of the marine riser system using the measured acceleration is presented. The method utilizes a system identification technique in determining the applied input load history from the measured response records. The identified input load is applied to commercial software for estimating fatigure life of a marine riser system.sured response records. The identified input load is applied to commercial software for estimating fatigure life of a marine riser system.
