Special Issue Information

Dear Colleagues,

This Special Issue aims to explore the applications of Computational Fluid Dynamics (CFD) in the analysis and design of floating offshore structures. Floating offshore structures are becoming increasingly important in the offshore industry due to their potential for cost-effective and environmentally friendly energy production. By accurately representing the fluid–structure interaction, CFD enables the optimization of system performance, which includes structural design, mooring systems, and dynamic positioning control strategies.

This Special Issue invites researchers and practitioners to contribute original research articles, review papers, and case studies that showcase the latest advancements in CFD applied to floating offshore structures. Topics of interest include, but are not limited to:

  • Numerical methods and algorithms for simulating fluid–structure interactions in the context of floating offshore structures.
  • Validation and verification of CFD models against experimental data or field measurements.
  • Optimization of floating offshore structures for improved performance, safety, and reliability.
  • Effects of environmental conditions (waves, currents, winds) on the behaviour and performance of floating offshore structures.
  • CFD-based design guidelines and best practices for floating offshore structures.
  • Multi-physics and multi-scale modelling of floating offshore structures.
  • Uncertainty quantification and risk analysis in CFD simulations of floating offshore structures.
  • Application of machine learning and artificial intelligence techniques in CFD modelling of floating offshore structures.

Excellent self-righting performance is important to guarantee the normal navigation of Unmanned Surface Vehicles (USVs) after overturning, and the restoring time is an important index in design requirements. Traditionally, the static stability method and experiments on full-scale vehicles were used to analyze the large-angle stability of the USV. However, when it comes to the analysis of self-righting performance, the traditional static stability method will cause improper integration, and experiments are not convenient. To solve these problems, an improved static stability method was proposed, and a whole self-righting process simulation of a physical model was finished. The numerical simulation method was used to predict the self-righting process of a USV under four working conditions. Firstly, a midpoint average method based on the static stability theory was adopted to compute the static restoring time, and the results were compared with the results of the references, which verifies the effectiveness of the midpoint average method. Also, the midpoint average method is convenient because it only needs the restoring arm curve, the width and the gravity center height. Then, a numerical simulation of a physical model in static water was finished, and an experiment for a physical model in a towing tank was conducted. Comparing the restoring time of the midpoint average method, the numerical simulation and the experiment, the results show that the numerical simulation has high accuracy. Moreover, the numerical simulation was used to predict the self-righting process and analyze the self-righting performance of a USV under four working conditions. Full article
