Therefore, this paper presents a data-driven framework to approximate sea surface velocity from spatially distributed observations, thus enabling efficient probability advection modeling across submesoscale domains. The system uses quasi-steady flow assumptions to approximate transient flows. To overcome the limitations of point measurements in capturing domain-wide circulation, the method employs a fusion of two simplified 2D flow models to approximate submesoscale dynamics, enabling complete velocity field reconstruction from scattered data. To ensure reliable flow dynamics, the approach iteratively adjusts boundary conditions in numerical simulations to align the simulated flow with observations. Experimental validation was conducted in Kvarner Bay using Global Positioning System (GPS) drifters. The results confirmed the system’s ability to replace computationally intensive transient simulations by approximating flow fields using model simplifications. The results demonstrate its efficiency in various cases, making it a practical tool for real-life submesoscale applications requiring swift passive scalar advection.</div></div>","PeriodicalId":8261,"journal":{"name":"Applied Ocean Research","volume":"162 ","pages":"Article 104699"},"PeriodicalIF":4.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723743","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}

The initiation and propagation of fatigue cracks can significantly compromise the structural capacity of offshore installations, affecting their fitness-for-service. For structures with cracks, failure often manifests through fracture and/or plastic collapse. The Failure Assessment Diagram (FAD) methodology is specifically designed to evaluate the interaction between fracture and plastic collapse, as recognised in industry standards such as BS 7910. While a considerable number of studies have explored this area, many have been confined to either deterministic analysis or probabilistic analysis without considering crack growth, hindering the capability of FAD to seamlessly support structural integrity management which demands a life-cycle approach. This paper seeks to address this research gap by introducing a structural reliability analysis methodology grounded in FAD principles. The methodology developed herein comprises three primary components: crack growth analysis, probabilistic FAD, and reliability updating. The first two components work in conjunction to compute the structural reliability, with the limit state function based on FAD formulation. Reliability updating is facilitated through conditional probability, enabling the incorporation of crack sizing data from inspections so that preserving FAD’s utility for post-inspection engineering critical assessment. An illustrative example is presented to demonstrate the application of the methodology on a tubular T-joint, including a comparison with evaluations based on critical crack size.

Developing an accurate dynamic model is essential for achieving rapid control. To address this, a scleronomic Lagrangian mechanics-informed neural network is adopted to model the autoloader’s nonlinear dynamics, which is then integrated into a CTM (computed torque method) - based trajectory tracking framework to enable model linearization. A novel sliding mode reaching law, termed the improved logarithmic-power reaching law, is subsequently proposed. It is combined with a terminal sliding surface to ensure rapid and robust stabilization of the resulting uncertain linear system, with the uncertainty primarily originating from base oscillations.

Compressive strength, failure strain, and Young′s modulus of specimen decreased with increasing total porosity. Comparative analysis of specimens with different vertical pore distributions indicated that total porosity primarily affected sea ice strength, and vertical pore distribution governed crack localization. The spatial arrangement of pores showed negligible influence on sea ice mechanical behavior.

The traditional and improved schemes are compared by interpolating pressure on the solid boundary from different particle distribution configurations, in which the normal distance-squared weighted method achieves the minimum relative error in reproducing the pressure value at the given position. Moreover, a novel stabilized method is proposed to overcome the fluctuated pressure-induced instability by using the acceleration and Newton`s law to transfer information.
