Advances in Marine Geotechnology and Offshore Structural Systems: Design, Monitoring and Performance

The rapid development of offshore infrastructure and coastal facilities has placed greater emphasis on improving the engineering behaviour of weak marine soils through advanced ground improvement techniques. Many offshore and onshore foundation systems must be constructed on soft, compressible, or loose seabed sediments that lack sufficient bearing capacity or exhibit excessive settlement under loading. To address these challenges, a range of ground improvement methods, such as deep soil mixing, vibro-compaction, marine stone columns, geosynthetics, and prefabricated vertical drains, have been developed and adapted for marine environments. Simultaneously, the design of foundation systems for offshore platforms, subsea pipelines, wind turbines, and coastal structures requires accurate geotechnical characterization, load-transfer modelling, and monitoring under static and dynamic conditions. Integration of these foundation systems with marine ground improvement is essential to ensure structural safety, serviceability, and long-term performance. This research topic focuses on the latest advances in the design, monitoring, and performance evaluation of offshore systems integrated with marine geotechnical considerations for both offshore and nearshore applications.The goal of this special issue is to address geotechnical and structural challenges encountered in the development of offshore and coastal infrastructure founded on weak, compressible, or variable marine soils. Offshore structures such as floating and fixed platforms, subsea pipelines, and wind turbine foundations require stable and reliable geotechnical support systems under complex loading from waves, currents, and operational activities. However, the engineering behaviour of marine soils often leads to issues such as bearing failure, excessive settlement, and long-term deformation. This special issue aims to explore recent advances in offshore geotechnical engineering, including site investigation techniques, constitutive modelling of seabed materials, and soil-structure interaction under static and dynamic loading. Additionally, it focuses on the application and optimization of marine ground improvement methods to enhance soil performance. Integrating geotechnical solutions with structural design, performance monitoring, and data-driven analysis will contribute to the development of resilient, durable, and sustainable offshore foundation systems.This Research Topic invites contributions that address the multifaceted geotechnical and structural challenges in offshore and coastal infrastructure development, particularly those founded on weak, compressible, or heterogeneous marine soils. Authors are encouraged to submit original research, case studies, and review articles focusing on themes such as site characterization in offshore environments, constitutive modelling of marine sediments, soil-structure interaction under static and dynamic loading, and performance-based design of offshore foundations. Studies on advanced numerical modelling, centrifuge testing, data-driven approaches, and field instrumentation for performance monitoring are also welcome. Emphasis is placed on innovative ground improvement techniques for marine applications, including prefabricated vertical drains, geosynthetics, deep mixing, and grouting. Manuscripts that integrate geotechnical insights with structural analysis for floating and fixed platforms, subsea systems, and offshore renewable energy structures are particularly encouraged. The objective is to promote sustainable, resilient, and optimized offshore foundation systems through interdisciplinary research and practical engineering solutions.
