Incorporating Epistemic Uncertainties in Ship Operability Study

open access: yesApplied Sciences
Ship operability diagrams are commonly defined based on the seakeeping analysis, showing which course and speed can safely be taken at the sea state to satisfy pre-defined seakeeping limiting values.

Prediction of Ship Motions in Irregular Waves Based on Response Amplitude Operators Evaluated Experimentally in Noise Waves

open access: yesPolish Maritime Research, 2021
The most common methods for predicting ship roll motions in a specified sea state are direct measurements of motions in a representative irregular wave realisation (time domain) or calculations of motions from response amplitude operators (RAOs) in the ...

Multi‐objective maritime vessel routing with safety considerations

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 1, Page 337-371, January 2027.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

open access: yesJournal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Fatigue Strength Assessment of Trimaran Cross‐Deck Structure Based on Spectral and Simplified Fatigue Method

open access: yesMathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In order to investigate the fatigue behaviour of trimaran cross‐deck structural details, the spectral and simplified fatigue analysis approaches are proposed. In spectral fatigue approach, three‐dimensional (3D) linear potential flow theory and global FE analysis are used for wave loads and stress transfer functions calculation; the stochastic spectral

Ship Formation Control Using Nonlinear Model Predictive Control With Safe Speed Constraints and Tidal Elevation Variations

open access: yesIET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
1. An adaptive speed control method is proposed to execute the ship formation trajectory tracking task more efficiently and safely while entering port with tidal elevation variations. 2. A distributed ship formation controller based on the leader‒follower structure is designed to govern the coordinated motion of formation members more flexibly. 3.

Sensitivity Analysis Based on Polynomial Chaos Expansions and Its Application in Ship Uncertainty‐Based Design Optimization

open access: yesMathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In order to truly reflect the ship performance under the influence of uncertainties, uncertainty‐based design optimization (UDO) for ships that fully considers various uncertainties in the early stage of design has gradually received more and more attention.
