A SVM-based Sensitivity Analysis Approach for Data-Driven Modeling of Ship Motion
Wang, Chunlin; Cheng, Xu; Chen, Shengyong; Li, Guoyuan; Zhang, Houxiang (Chapter, 2018)This paper presents a novel method that combines support vector machine (SVM) with sensitivity analysis (SA) to analyze sensor data for ship motion modeling. In order to investigate how each model input contributes to the ... -
Automated Modal Parameters Identification During Ice-Structure Interactions
Wang, Chunlin; Nord, Torodd Skjerve; Li, Guoyuan (Chapter, 2022)Offshore structures are prone to damage caused by ice-induced vibrations. It is presently unknown to what extent different ice conditions change the properties of the structure, such as natural frequency, damping ratio, ... -
Data analysis and modelling for onboard support of marine operations
Wang, Chunlin (Doctoral theses at NTNU;2023:253, Doctoral thesis, 2023)The ever-increasing exploration of ocean resources has led to more frequent and intensive marine operations. However, marine operations are vulnerable to accidents due to unpredictable environmental factors and human ... -
A sensitivity quantification approach to significance analysis of thrusters in dynamic positioning operations.
Wang, Chunlin; Li, Guoyuan; Skulstad, Robert; Cheng, Xu; Osen, Ottar Laurits; Zhang, Houxiang (Peer reviewed; Journal article, 2021)The safety of offshore operations is highly dependent on the dynamic positioning (DP) capability of a vessel. Meanwhile, DP capability comes down to the ability of the thrust generated by thrusters to counteract environmental ... -
Towards uncertainty and sensitivity analysis for modal parameters identification during ice–structure interaction
Wang, Chunlin; Nord, Torodd Skjerve; Ziemer, Gesa; Li, Guoyuan (Peer reviewed; Journal article, 2023)The integrity of offshore structures is prone to the threat of drifting sea ice. By exciting the natural frequencies of the ice–structure interaction system, severe vibrations may occur. For a better understanding of how ... -
Uncertainty and sensitivity analysis for the performance evaluation of ship dynamical model
Wang, Chunlin; Wang, Tongtong; Nord, Torodd Skjerve; Zhang, Houxiang; Li, Guoyuan; Osen, Ottar (Chapter, 2022)Model uncertainty is pervasive and inherent in the engineering field. It could bring potential risks in real applications, especially for ship behaviour prediction under environmental disturbances. The evaluation and ...
