“…Currently, there are a limited and scattered number of studies on the countermeasures (and their technical requirements) for lessening the scouring effect; this is due to their to varied hydraulic situations, including stability, reliability, and resistance capacity. Previously published literature reviews (such as [21,22]) are limited to monopile foundations only and subsequently have failed to provide a comprehensive overview of scour protection measures for OWTs (including the effectiveness and ecological impact of scour protection measures with different foundation types). Therefore, there is a need to credibly summarize scour protection measures for OWTs, encompassing related research advances made in recent years to develop an integrated portfolio of scour protection measures for OWTs and inform future research and policy needs.…”

Offshore wind energy is considered as one of the most promising resources of clean and renewable energy to replace fossil fuels. Additionally, its cost is expected to be lower than onshore wind energy as the technology matures. Offshore wind turbines (OWTs) normally operate in harsh ocean environments, which could impact their structural integrity. Scour erosion around foundations of OWTs can substantially change the overall stiffness of these structures and shorten their lifetime. Currently, there are a limited number of studies on countermeasures and their engineering requirements for decreasing the scouring effect; this is due to their different hydraulic circumstances, such as their stability, reliability, and resistance capacity. To this end, advancements in scour protection measures in the offshore energy sector are evaluated in this paper through a thorough and critical review following the PRISMA systematic literature mapping approach. This includes 68 papers on scour protection and over 30 scour protection designs for various types of wind turbine foundations. Here, we aim to provide an overview of the latest scouring protection measures and their comprehensive assessment, as well as their prospects and future challenges. The findings of this study will provide key insights into scour protection measures for OWTs and will subsequently contribute to the future growth of the offshore renewable energy sector.

“…This is a critical issue for the reliable design of the offshore wind turbine foundations. In the literature, several studies are available that utilize CFD simulations to examine the monopile-type foundation in breaking waves, [23][24][25] analyze the slamming effects, 26,27 investigate the flow and scour around the monopile 28,29 and identify the second-order hydrodynamic loads. 30,31 The high-fidelity simulations provide an accurate solution yet demand expensive computational cost.…”

Accurately determining hydrodynamic force statistics is crucial for designing offshore engineering structures, including offshore wind turbine foundations, due to the significant impact of nonlinear wave–structure interactions. However, obtaining precise load statistics often involves computationally intensive simulations. Furthermore, the estimation of statistics using current practices is subject to ongoing discussion due to the inherent uncertainty involved. To address these challenges, we present a novel machine learning framework that leverages data‐driven surrogate modeling to predict hydrodynamic loads on monopile foundations while reducing reliance on costly simulations and facilitate the load statistics reconstruction. The primary advantage of our approach is the significant reduction in evaluation time compared to traditional modeling methods. The novelty of our framework lies in its efficient construction of the surrogate model, utilizing the Gaussian process regression machine learning technique and a Bayesian active learning method to sequentially sample wave episodes that contribute to accurate predictions of extreme hydrodynamic forces. Additionally, a spectrum transfer technique combines computational fluid dynamics (CFD) results from both quiescent and extreme waves, further reducing data requirements. This study focuses on reducing the dimensionality of stochastic irregular wave episodes and their associated hydrodynamic force time series. Although the dimensionality reduction is linear, Gaussian process regression successfully captures high‐order correlations. Furthermore, our framework incorporates built‐in uncertainty quantification capabilities, facilitating efficient parameter sampling using traditional CFD tools. This paper provides comprehensive implementation details and demonstrates the effectiveness of our approach in delivering reliable statistics for hydrodynamic loads while overcoming the computational cost constraints associated with classical modeling methods.

“…Scouring is a significant and crucial process that may take place near the piers and abutments and cause the bridge to collapse catastrophically [1]. There are significant parallels between the local scour process and what happens around piers and abutments [2][3][4]. As a result, it's crucial to accurately and thoroughly estimate the local scour around piers and abutments.…”

In hydraulic engineering and design of infrastructure, scour, the erosive process that threatens the integrity of bridge abutments, is a crucial problem. This review study seeks to give a thorough examination of scour reduction tactics near bridge abutments, with an emphasis on the precision, efficacy, and novel methodologies used in recent studies. We summarize and critically evaluate the primary approaches and results from research in the scour reduction sector. We examine fundamental scour mechanisms, cutting-edge scour reduction methods, numerical modeling and simulations, and real-world case studies throughout the study. Our study indicates the need for more research to close existing gaps and illustrates the advantages and disadvantages of the present scour mitigation measures. This work aims to combine this multitude of information in order to advise and direct academics, designers, and planners in their efforts to reduce scour-related hazards to bridge abutments, therefore maintaining the durability and resilience of crucial infrastructure. This provides analysis of scour mitigation methods provides insightful tips for boosting the durability and safety of bridge structures across the world.
