Banergy: The Bengal-Based Marine Robotics Startup Building India’s Underwater Future
India’s startup ecosystem is often associated with fintech, SaaS, artificial intelligence, and drone technology. However, a Bengal-based company is quietly carving out a niche in an emerging and highly specialised sector, marine robotics.
Founded by Swarnab Banerjee and Rishav Banerjee, Banergy is building a marine robotics ecosystem from eastern India. The company manufactures advanced marine robotic systems, including remotely operated vehicles (ROVs) and unmanned surface vessels (USVs), from its facilities in Bankura, West Bengal, and Balasore, Odisha.
At a time when India is increasing investments in maritime infrastructure, inland waterways, disaster management, and underwater surveillance, Banergy is positioning itself as a homegrown deep-tech company with real-world applications.
What Is Banergy?
Banergy is a marine robotics manufacturing company focused on developing robotic technologies designed for rivers, lakes, ports, and oceans. The company specialises in creating underwater and surface-level robotic systems that can carry out tasks that are often difficult, risky, or expensive for human teams.
Unlike conventional robotics startups, Banergy is focused on the marine and underwater segment, an area that remains relatively untapped in India.
Its mission goes beyond manufacturing products. The founders aim to create a larger marine robotics ecosystem from Bengal, combining technology, engineering, and innovation to solve challenges across industries.
What Does Banergy Manufacture?
Banergy develops two major categories of marine robotics technology:
1. Remotely Operated Vehicles (ROVs)
ROVs are underwater robotic systems controlled remotely by operators. These robots are designed to function beneath water surfaces and can be deployed for a variety of operational needs.
- ROVs are commonly used for:
- Underwater inspections
- Bridge and infrastructure monitoring
- Search and rescue operations
- Submarine and marine surveys
- Disaster response activities
- River and ocean bed analysis
In situations where human diving may be risky, expensive, or technically challenging, ROVs provide safer and more efficient alternatives.
2. Unmanned Surface Vessels (USVs)
USVs are robotic boats that can operate autonomously or be remotely controlled on water surfaces.
- These vessels can support:
- Waterbody surveillance
- Hydrographic surveys
- Environmental monitoring
- Security operations
- Water quality assessments
- Disaster management support
As India expands its focus on coastal security and inland waterways, technologies like USVs are expected to play an increasingly important role.
Banergy’s Presence in Bengal and Odisha
One of the most unique aspects of Banergy is its manufacturing footprint.
The company manufactures marine robotics from Bankura in West Bengal and Balasore in Odisha — a notable achievement considering most deep-tech manufacturing in India is concentrated in cities such as Bengaluru, Hyderabad, or Pune.
This makes Banergy one of the few companies from eastern India building advanced marine robotic technologies at scale.
For Bengal, it signals the rise of specialised deep-tech innovation beyond traditional IT and service industries.
Institutions Taking Notice of Banergy
Banergy’s work has already caught the attention of several major institutions and government-linked organisations.
Its marine robotics technology has impressed entities such as:
National Institute of Oceanography (NIO)
- Indian Railways
- National Disaster Response Force (NDRF)
- Kolkata Police
The interest from these institutions reflects the growing importance of underwater robotics in sectors such as public safety, infrastructure inspection, marine research, and emergency response.
For example, underwater robots can help inspect bridge foundations, monitor submerged structures, support rescue operations during floods, and improve maritime surveillance.
Why Marine Robotics Matters for India
India has over 7,500 kilometres of coastline, extensive river systems, expanding ports, and growing maritime ambitions.
As the country invests in coastal infrastructure, shipping, disaster resilience, inland waterways, and blue economy initiatives, marine robotics could become a key enabling technology.
Applications include:
- Port inspections and maintenance
- Underwater infrastructure assessment
- Flood and disaster response
- Scientific ocean exploration
- Security and surveillance
- Environmental and water monitoring
Companies like Banergy are helping India reduce dependence on imported underwater technologies by building indigenous solutions.
Bengal’s Emerging Deep-Tech Story
West Bengal has historically been recognised for education, research, and industrial manufacturing. In recent years, there has also been growing momentum around startups and technology-led businesses.
Banergy’s story highlights how Bengal-based founders are increasingly entering specialised sectors such as robotics, advanced engineering, and industrial technology.
The company represents a new generation of innovation emerging from the region — one that combines manufacturing, research, and real-world problem solving.
Final Thoughts
Banergy may still be an emerging name in India’s startup landscape, but its focus on marine robotics places it in a highly strategic and future-facing industry.
By building ROVs and USVs from facilities in Bankura and Balasore, the company is not only advancing marine technology but also putting Bengal on the map in an area where very few Indian companies operate.
As marine robotics gains relevance across disaster management, infrastructure monitoring, research, and maritime operations, Banergy is a startup worth watching in the years ahead.
