Abstract

The study of hydroelasticity dates to the 19th century. Major theoretical developments and applications focused on the behavior of slender ship structures (Bishop and Price, 1979) and ship design for safety applications (Hirdaris and Temarel, 2009). The ocean engineering principles involved in the subject of hydroelasticity are multidisciplinary. They combine the engineering science developments in fluid mechanics and structural dynamics to study the coupled interaction and the dynamic response between fluids and deformable maritime artefacts in concurrent or extreme environmental conditions. Over time, the importance of hydroelasticity has continued to grow, becoming a crucial consideration in the design and analysis of a wide range of marine structures such as high-speed craft (Faltinsen, 2005) and offshore platforms (Sarpkaya, 2014). More recently the subject became increasingly relevant to the emerging class of offshore renewable energy systems as it may help predict the dynamic response to various environmental loads (e.g. waves, currents, and wind) and validate concurrent and emerging designs. This special issue seeks to capture the latest advancements in the field of hydroelasticity and its diverse applications across the broader marine sector. The 19 papers presented are written by researchers representing leading research institutes, universities and industry from 14 countries. It features state of the art research on the mathematical, and computational methods underpinning the hydroelasticity analysis methods used to understand the dynamic response of ships (Xing et al., 2025), (Jiao et al., 2025), (Ma et al., 2024), (Chen et al., 2024) and very large floating structures (VLFS) (Zhi, 2025), (Zhang et al., 2025), (Lee et al., 2025), (Jia et al., 2025). In the VLFS sector the application research papers presented focus on bridge dynamics (Ye et al., 2025) and floating tunnels (Ji et al., 2025), (Ding et al., 2025). Papers on floating renewables outline recent advances with application floating photovoltaics (Chen et al., 2025), (Shi et al., 2025a), (Shi et al., 2025b), wind turbine installations (Imafidon et al., 2025), (Leimeister and Bouman, 2015), (Dong et al., 2025), marine trains (Zhu et al., 2025). A review paper outlining strategic directions of the subject is also presented (Tavakoli et al., 2025). By bringing together research from both the marine and renewable energy domains, it provides to provide a comprehensive, cross-disciplinary understanding of the critical role fundamental and application driven hydroelasticity research plays in ensuring safe and sustainable design.
