Component-level verification shows that Zwave accurately reproduces target wave spectra, and its hydrodynamic results align well with WAMIT in the frequency domain and Orcaflex in the time domain. Furthermore, with corrected Morison coefficients, Zwave successfully captures the resonance responses observed in wave basin tests.

The soil profile was characterized using one-dimensional consolidation tests, as well as small-scale vane shear, T-bar penetration, and ball penetration tests. Three test configurations were carried out: pullout extraction tests, foundation compression bearing capacity, and a combination between the two previous types. Stress–displacement and pore pressure–displacement curves for pull-out extraction tests were similar in shape but inversely proportional, which shows that suction contributes to sustaining the bond created between the soil and the mudmat foundation. Suction development was directly proportional to the test rate. These findings demonstrate that decommissioning processes must have adequate controls and avoid high-speed extractions rates. The outcomes of foundation compression bearing capacity tests indicated increases in stress and pore pressure corresponding to increases in loading rate.

Depending on input parameters, the approach can account for Gaussian, non-Gaussian, wide-banded and narrow-banded processes in a practical way, which is not achieved by existing methods. For long-term fatigue assessments, simplified approaches are possible by selecting a conservative representative bias factor at global minimum, while more accurate estimates can be found by more careful selection of bias factor per short-term condition.

However, large lifting loads and harsh conditions during manual operations can cause unstable postures or structural failures, potentially leading to serious economic losses and personal injuries. To address these safety concerns, comprehensive monitoring of RFC operations is essential. Thus, this study proposes a digital twin (DT)-driven structure safety monitoring method based on multi-fidelity surrogate model (MFSM). In the implementation, the structural and functional characteristics of actual RFCs are referenced to build an RFC physical entity. By identifying key operational safety indicators, a sensor-based data acquisition module for RFC entity is developed. Relying on the entity, finite element simulations and actual experiments are then conducted to generate multi-fidelity training data of RFC operational safety, which are used to establish corresponding MFSMs. By Unity3D engine, a virtual interaction platform for data fusion is created for safety monitoring, enabling real-time synchronization from the RFC physical entity to DT model. Finally, physical safety monitoring experiments are conducted on RFC lifting operations. Experiment results demonstrate that the proposed method delivers high real-time performance and accuracy, effectively meeting the engineering requirements for RFC lifting safety monitoring.</div></div>","PeriodicalId":49879,"journal":{"name":"Marine Structures","volume":"105 ","pages":"Article 103925"},"PeriodicalIF":5.1,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144917813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous study has shown that the occurrence in level ice fields follows a Poisson distribution and the time intervals follow an exponential distribution. Based on the measurement data on Polar oly and Research Vessel (PSRV) S.A.

A mixture of exponential distributions is proposed to fit the time intervals in floe ice fields and the statistical test is adopted to evaluate the goodness of fit. The relationships between the parameters of ice conditions and distribution models are discussed. Monte Carlo method and theoretical method are adopted to obtain the ice load occurrence based on the distribution of time intervals. To assess the uncertainty associated with the estimated parameters and the ice load occurrence, Bayesian approach and Bootstrapping are adopted.
