摘要

This paper investigates advanced techniques for repairing underwater joints in fixed offshore jacket structures, focusing on critical challenges such as corrosion, fatigue, and structural degradation. It provides a comprehensive review of conventional repair methods and introduces emerging technologies, including composite wrapping systems, remotely operated vehicle (ROV)-assisted interventions, hyperbaric welding, and underwater additive manufacturing. Key factors such as structural integrity, safety, cost-efficiency, and compliance with offshore engineering standards are thoroughly examined. The study integrates real-world case studies and explores future trends, such as AI-driven structural health monitoring and the application of smart materials. These innovations aim to significantly extend the service life of offshore assets while minimizing operational risks and environmental impact.
