IIT Madras Develops Real-Time Digital Twin Platform 'SEANAV' for Autonomous Maritime Navigation
Why in the News?
Researchers at the **Department of Ocean Engineering, IIT Madras**, have developed **'SEANAV' (Sea Navigation)**, a real-time **digital twin platform** that enables testing, validation, and training of autonomous maritime navigation systems in realistic virtual environments.
Key Features / Major Points:
- Technology & Platform Capabilities:
- Built on the **Unity3D engine**, SEANAV creates a high-fidelity digital twin that accurately replicates ocean waves, vessel hydrodynamics, and complex maritime environments.
- The platform has been calibrated using a benchmark **320-metre tanker vessel**, ensuring virtual results closely match real-world commercial shipping operations.
- Strategic & National Alignment:
- Maritime shipping handles **over 80% of global trade**. SEANAV eliminates the high cost, complexity, and hazards of testing autonomous algorithms in physical waters.
- Aligns with India’s **Sagarmala Programme** and **Maritime India Vision 2030**, promoting smart ports, digital technology, and autonomous maritime systems.
- Supports multi-vessel simulations for coastal surveillance, search-and-rescue operations, and maritime defence.
- Operational & Environmental Safety:
- Project Lead Dr. Suresh Rajendran highlighted its potential to strengthen safety at major Indian ports like Chennai, Mumbai, Visakhapatnam, and Kochi by preventing collisions and groundings.
- Optimised navigation reduces fuel consumption, carbon emissions, and risks of ecological disasters like oil spills.
