Large Floating Solutions builds on the foundations laid in Large Floating Structures: Technological Advances, extending the analysis to the next generation of Very Large Floating Structures (VLFS) as integrated, climate-adaptive urban systems. This volume provides a comprehensive examination of the engineering, environmental, and architectural innovations required to deliver modular, resilient floating cities, alongside offshore energy, aquaculture, and transport infrastructure. It addresses the complex legal, regulatory, and governance frameworks that underpin buoyant urbanism, including property rights, environmental compliance, and international law, and considers the role of artificial intelligence and autonomous maritime systems in urban management. Together, these contributions position floating infrastructure as a critical solution to escalating global water challenges.
