| Summary: | Abstract Accurately measuring the dynamic response in marine structures is crucial for ensuring service safety. Here we developed a method for reconstructing the dynamic displacement of floating structures based on acceleration measurements, addressing the challenges posed by the limitations of non-contact measurement devices due to the absence of fixed reference points in marine environments. This method avoids the issues of transition and low-frequency component loss typically encountered in integration-based reconstruction methods by the precise removal of drift terms, while achieving dual improvements in both reconstruction accuracy and efficiency compared to recent methods. A comprehensive comparison is made between the proposed method and widely used displacement measurement devices in physical model testing and field applications of offshore floating structures, validating the broad potential for applications requiring structural displacement measurement in complex marine environments. |
