Special Issue Information

Dear Colleagues,

The Special Issue delves into the complex realm of ocean wave loads and their profound impact on various marine structures. The dynamic nature of the marine environment necessitates a comprehensive understanding of the forces exerted by waves on these structures, which include offshore platforms, ships, coastal infrastructure, and renewable energy installations. This Special Issue welcomes submissions that address various aspects of wave load analysis, including, but not limited to, the following:

  • Wave–Structure Interaction: Numerical simulations, experimental investigations, and analytical approaches to studying wave–structure interactions and their impact on structural integrity and performance.
  • Extreme Wave Loads: Studies on the prediction, characterization, and mitigation of extreme wave loads, including rogue waves and hurricane-driven waves.
  • Wave-Induced Vibrations: Research on the dynamic response and vibrations induced by ocean waves, with a focus on fatigue and structural health monitoring.
  • Wave–Structure Interaction in Renewable Energy: Investigations into the impact of wave loads on offshore wind turbines, wave energy converters, and other renewable energy installations, with an emphasis on design optimization.
  • Wave Loads on Coastal Infrastructure: Assessments of wave loads on coastal structures, such as seawalls, breakwaters, and piers, considering climate change and rises in sea level.
  • Ship Design and Performance: Studies on the hydrodynamics of ships and their response to wave-induced loads, contributing to safer and more efficient ship design.

The design of coastal and hydraulic structures must account for extreme conditions, such as wave overtop**, and consider variables that may not be relevant under normal circumstances to ensure safety. This research investigates the characteristics of air cavity pressure and cavity water depth beside an overflowed vertical caisson breakwater, focusing on the influence of flow conditions and hydraulic parameters for a slowly varying, surging-type tsunami. A physical model was used to conduct controlled experiments, enabling the study to explore various scenarios, including subcritical and supercritical downstream flows with varying downstream flume outlet heights and different upstream water depths. Dimensionless equations for air cavity pressure and cavity water depth were derived through multivariate regression analysis, providing a systematic approach to analyze their behaviors under different flow conditions. The results show that air cavity pressure is significantly influenced by the presence of air in the cavity, with a transition from fully ventilated to partially or non-ventilated conditions as the upstream water depth increases. Cavity water depth is observed to be deeper in the non-ventilated case, aligning with previous studies. The derived dimensionless equations demonstrate strong correlations, offering valuable tools for predicting air cavity pressure and cavity water depth under various scenarios, contributing to the design and analysis of hydraulic structures. This study provides insights into wave-structure interactions, extreme wave loads, and the dynamic responses of coastal infrastructures under wave-induced conditions. Overall, this research advances our understanding of air cavity pressure and cavity water depth behaviors, providing essential data for optimizing the design, performance, and safety of hydraulic and marine structures in response to complex ocean wave loads.

The suspended configuration of inter-array power cables between floating offshore wind turbines necessitates using various ancillary equipment, such as buoy elements and bend stiffeners, to maintain the desired cable geometry. The failure analysis is an important step in the design of an inter-array dynamic power cable layout. This study investigates the impact of buoy element failures on the structural integrity and fatigue life of inter-array power cable configurations in offshore environments, focusing on four environmental conditions representative of the North Sea. Utilizing numerical simulations and fatigue analysis in OrcaFlex, static and dynamic analyses are conducted to assess maximum tension, minimum bend radius (MBR), and fatigue life under single and two failure scenarios of buoy elements. The results indicate that single buoy failures significantly increase maximum tension at hang-off points. At the same time, MBR is found to be the smallest at the failure position, aiding in failure point identification. In addition, for the two buoy element failure scenarios, the maximum tension increase poses risks to structural integrity, while MBR and fatigue life have high sensitivity to the applied environmental conditions.

Experimental measurement and numerical simulations were carried out for investigating the impact loading behavior of platform decks under regular and irregular wave actions. In the numerical simulation section, a full-scale numerical wave tank was established using STAR-CCM+ software. A decreased tendency can be observed for an increased relative length of platform when the incident wave length is double the deck length. The increased deck height can also decrease impact loading on the platform, which is due to the platform being far away from the incident wave. Impact loading on the deck decreases with the increase in inclination angle, which can be explained by the deck bottom being directly exposed to the incident wave at negative inclination angles. Finally, the variation tendency of impact loading on platform decks under irregular wave actions is similar to that under regular wave actions, including the averaged values and significant values.
