Ship abnormal behaviour detection based on AIS data at the approach to ports
Reliability Engineering & System Safety
— 2026 — Elsevier
This study proposes a novel framework for abnormal ship behaviour detection, extracting traffic characteristics in port approach waters from collected Automatic Identification System (AIS) data and establishing corresponding anomaly indicators to measure the degree of abnormal vessel behaviour. The …

Cartography and Geographic Information Science
— 2026 — Taylor & Francis
This article presents an innovative collaborative value modeling process to engage policy-makers and other stakeholders in Portugal in discussing relevant geographic information for COVID-19 response. The process determines what geographic information should be included in map-based dashboards to ef…

A domain-adaptive deep learning framework that learns sea-state-invariant features under varying operational domains is proposed. This allows real-time prediction of mooring line tension in floating offshore wind turbines, which is essential for health monitoring under uncertain sea states and is an…

Ocean Engineering
— 2026 — Elsevier
A mathematical model has been introduced to investigate the hydroelastic behavior of an array of moored floating circular modules in a water of limited depth. This model relies on principles of linearized small-amplitude theory, employing the Timoshenko-Mindlin beam theory to model the floating modu…

Coupled dynamics of a point absorber array with a shared mooring system
Ocean Engineering
— 2026 — Elvesier
This study presents a coupled Computational Fluid Dynamics model capable of simulating wave energy converter (WEC) arrays with shared mooring systems. The model integrates the OpenFOAM solver, via the foamMooring library, with the lumped-mass mooring solver MoorDyn to simulate mooring dynamics. The …

Grey-based failure mode and effect analysis of floating offshore wind turbines
Ocean Engineering
— 2026 — Elvesier
This paper proposes a Grey-based Failure Mode and Effect Analysis (G-FMEA) approach to complete the failure analysis of floating offshore wind turbines. A multi-level weighting method is first developed to evaluate interactions between systems and components. A Grey Priority Number is then determine…

Uncertainty analysis of a CFD solver for predicting ship motions in head waves
Ocean Engineering
— 2026 — Elvesier
This study quantifies simulation uncertainties arising from discretisation and modelling uncertainties in a CFD solver used to predict the motions of a containership in head waves at two forward speeds. Simulations were conducted in regular head waves with various wavelengths to predict the heave an…
