[revised] V1-P6 A MOVABLE BARRIER FOR RAPID COASTAL PROTECTION

Scalable and Sustainable Coastal Barriers for Wide and Deep Channels

This project aims to advance a retractable, modular and pier-free storm surge barrier deployed and temporarily supported by a synchronized fleet of jack-up platforms.

Wide, deep and heavily used channels are difficult to protect with conventional seawalls, caissons or tidal gates. These systems often require permanent piers, extensive foundations or irreversible seabed occupation, which can restrict navigation, alter sea views and hinder future adaptation. There is no established design or control framework for a large, temporary barrier that can span such waterways.

Research Approach

  • New models will examine wave-current-structure interaction across a multi-body telescopic system supported by temporary foundations.
  • The project will examine soil disturbance and cyclic loading responses in seabed as the jack up platforms are installed, retrieved and redeployed.
  • The team will develop control and synchronisation strategies for multiple platforms, alongside design approaches for stability, maintenance, durability, adaptability and cost efficiency.

Why This Matters

  • Provides wide-span protection without permanent vertical obstructions in the channel.
  • Keeps waterways open for navigation and preserves sea views under normal conditions.
  • Reduces the need for large permanent structures on the seabed or coastline.
  • Offers an adaptable option for emergency, transitional or longer-term protection as sea levels and coastal needs change.
