Special Issue Information

Dear Colleagues,

In the field of offshore hydrodynamics, the interaction between hydrodynamic environment and structures is a critical area of study, influencing the design, construction, and operation of coastal and offshore structures. Understanding these interactions is crucial for predicting how structures respond to complex hydrodynamic forces, such as waves and currents. It also helps assess the impact on surrounding flow fields and ecosystems. Recent advancements in numerical simulations, experimental techniques, and analytical methods have enabled researchers to tackle increasingly intricate scenarios involving sophisticated structural designs and extreme hydrodynamic conditions.

The aim of this Special Issue is to provide a platform for scholars and engineers to present cutting-edge research on offshore hydrodynamics. This Special Issue aims to advance the frontiers of knowledge in ocean engineering and foster innovative solutions to address global challenges in hydrodynamic environments. Both original research and review articles are encouraged. Topics of interest to this collection include, but are not limited to, the following:

  1. Interactions between waves/currents and structures;
  2. Hydrodynamic optimization of floating structures;
  3. Computational fluid hydrodynamics;
  4. Ocean renewable energy;
  5. Dynamics of floating wind turbines.

The offshore wind industry is increasingly moving towards larger turbines. The growth in rotor size and aerodynamic loads necessitates larger monopile foundations. This increased foundation height results in a monopile that exhibits pronounced slenderness and flexibility. Consequently, the fixed-bottom monopile becomes more susceptible to wave loads, which can induce nonlinear vibrations in complex wave environments. Extensive physical model experiments have been conducted in a wave tank to study the nonlinear vibration characteristics of a fixed-bottom monopile under regular wave action. The experimental results demonstrate that when the wave period is close to twice the resonant period of the model, the vibration response of the monopile increases significantly. Under these conditions, a second harmonic resonance occurs, with the amplitude of the second harmonic component being more than twice that of the fundamental (wave frequency) component. Additionally, the maximum run-up around the model exhibits a W-shaped distribution in the circumferential direction, with the highest run-up observed on the incident wave side. The wave pressure at the water surface is the greatest and increases with wave height, while the pressure below the water surface gradually increases with the measurement height. Full article
