Maharashtra is set to make history in India’s tourism sector with the launch of the country’s first-ever submarine tourism project, backed by an investment of over ₹112 crore. Designed to offer visitors a rare underwater experience along the Konkan coast, the initiative is expected to redefine coastal tourism in India and place Sindhudurg on the global marine tourism map.
The ambitious project blends engineering innovation, experiential travel, and environmental conservation, allowing tourists to explore marine life beneath the Arabian Sea through controlled and eco-sensitive submarine rides.
India’s First Submarine Tourism Project Explained
The project has received revised administrative approval of ₹112.46 crore from the Maharashtra government. It includes the development of:
- A 24-seater battery-operated passenger submarine
- An underwater museum
- An artificial coral reef created using a decommissioned naval vessel
At the heart of the initiative is the Maharashtra Tourism Development Corporation, which is overseeing execution and coordination with multiple agencies.
Role of INS Guldar and the Artificial Reef
A key highlight of the project is the transformation of the decommissioned INS Guldar into an underwater museum and artificial reef.
By sinking the vessel in a controlled manner:
- Artificial coral reefs will be created
- Marine biodiversity is expected to increase
- Divers and submarine passengers will gain a unique underwater viewing experience
This approach mirrors successful underwater tourism models seen in Southeast Asia and parts of Europe.
Passenger Submarine by Mazagon Dock Shipbuilders
A separate but closely linked proposal has been cleared for the construction of a 24-seater passenger submarine, to be developed by Mazagon Dock Shipbuilders Ltd.
Key financial details include:
- Total permissible cost: ₹110.58 crore
- Government funding (Centre + State): ₹84 crore
- Remaining ₹26.58 crore to be raised by MDL through Viability Gap Funding or alternate sources
The submarine will be battery-powered, ensuring minimal environmental impact while offering safe and controlled underwater access.
Funding Structure and Government Support
The project was first announced in the 2018–19 Maharashtra state budget and initially approved at ₹65.55 crore. Since then, funding has been strengthened through central support.
In November 2024, the Union government approved ₹46.91 crore under the Special Assistance Scheme for Capital Investment, as part of the “Development of Iconic Tourist Centres to Global Scale” programme. Of this, 66% of the funds were released to Maharashtra, with ₹30.96 crore already disbursed to MTDC.
The revised cost reflects enhanced safety standards, advanced submarine technology, and expanded tourism scope aligned with international benchmarks.
Additional Infrastructure and Tourism Facilities
Beyond the submarine and underwater museum, the project requires supporting infrastructure estimated at ₹18.30 crore. This will be funded through:
- The Regional Tourism Development Scheme
- Other approved tourism funding avenues
MTDC has been asked to submit a separate proposal for these components, ensuring that funds are used strictly for approved purposes.
Why Sindhudurg Is Central to the Project
Located along Maharashtra’s scenic Konkan coastline, Sindhudurg has long been known for its beaches, forts, and relatively untouched marine environment.
Tourism officials believe the submarine project will:
- Attract high-value domestic and international tourists
- Encourage longer stays and premium spending
- Create a niche identity for Sindhudurg as a marine tourism hub
The focus is on high-value, low-footfall tourism, reducing environmental stress while maximising economic impact.
Environmental and Tourism Impact
Officials emphasise that the project is designed to be eco-sensitive. Controlled submarine rides, regulated visitor numbers, and artificial reef creation are expected to:
- Support marine biodiversity
- Promote awareness of underwater ecosystems
- Encourage sustainable tourism practices
If successful, the model could be replicated along other parts of India’s coastline.
