Vibration analysis for the determination of modal parameters of steel catenary risers based on response-only data

Similarity-based Damage Detection in Offshore Jacket Structures

“…이러한 해석기법을 활용하여 해양구 조물과 해양라이저의 고유진동수를 분석하려는 몇몇 연구가 진 행되었다 (Yang et al, 2006;Li et al, 2012;Rivero-Angeles et al, 2014). 구조물에 부착된 센서를 통해 점검 주기별 획득된 고 유진동수들을 정리하면 다음과 같다.…”

A nonlinear mechanical model for deepwater steel lazy-wave riser transfer process during installation

“…A lot of workers have conducted extensive studies on the SCR including static response, dynamic behavior, pipe-soil interaction and the installation analyses [4][5][6][7][8][9][10][11][12][13]. The installation of the pipeline makes influence of the riser's service life and is an important research direction.…”

Stochastic dynamic analysis of marine risers considering fluid-structure interaction and system uncertainties

“…The dynamic response characteristics were obtained from the analysis of strain responses, displacement amplitudes, dominant modes, response frequencies and drag force coefficients. Rivero-Angeles et al [5] presented a comparison study on the modal identification of offshore risers by using two methods, namely, the Frequency Domain Decomposition Method and the Conventional Spectral Analysis Method, with numerical simulation data. Gao et al [6] proposed a method to study riser's fatigue damage induced by the vortex-induced vibrations.…”
