Author – Ritesh Ranjan: Institute of Technology Madras has taken another major step towards strengthening India’s maritime research and innovation ecosystem. The institute has launched a state-of-the-art Circulating Water Tunnel Facility at its Discovery campus in Thaiyur near Chennai. Built with Rs. 4.5 crore in CSR funding from Mazagon Dock Shipbuilders Limited, the facility is expected to support advanced research in ocean engineering, ship design, hydrodynamics, naval technology and student training.
The facility was inaugurated on 20 May 2026 in the presence of IIT Madras Director Prof. V. Kamakoti, Dean of Alumni and Corporate Relations Prof. Ashwin Mahalingam, and Mazagon Dock Shipbuilders Limited Chairman and Managing Director Capt. Jagmohan, IN (Retd). Senior representatives from both IIT Madras and MDL were also present at the event.
This launch marks an important milestone for India’s ocean engineering research infrastructure. As India expands its focus on shipbuilding, naval systems, offshore engineering and maritime technology, facilities like this can help bridge the gap between academic research and real-world industrial applications.
What is the new Circulating Water Tunnel Facility?
The newly launched facility is a hybrid wind and circulating water channel system. It is now fully operational and has been designed to provide a stable and uniform-flow test section for experimental research. This means researchers can study the behaviour of objects and models under controlled flow conditions, which is essential for understanding performance in marine environments.
The facility will be used to test and analyse ship models, propellers, bluff bodies, marine vehicles, offshore platforms and underwater structures. These experiments are important because real-world marine systems are exposed to complex water-flow conditions. Before a ship, propeller, submarine component or offshore structure is built at full scale, engineers need to understand how it will behave in water.
A circulating water tunnel allows researchers to recreate such conditions inside a laboratory. By doing so, they can study drag, lift, turbulence, stability, flow separation and other hydrodynamic factors. These insights can help improve designs, reduce energy loss, increase safety and lower development costs.
Why this facility is important for ocean engineering
Ocean engineering is a highly practical and research-intensive field. It deals with the design and development of ships, marine structures, underwater vehicles, offshore systems and coastal infrastructure. For this field, experimental testing is extremely important.
Computer simulations are useful, but physical experiments remain essential for validating designs. A water tunnel gives researchers a controlled environment where they can observe fluid flow and test models repeatedly. This helps in identifying problems early and improving designs before they are used in real-world applications.
The IIT Madras facility will support research in hydrodynamics, marine vehicle design, propeller performance, underwater systems and offshore engineering. It will also help students understand how theoretical concepts are applied in real engineering situations.
For India, this is especially significant because the country is working to expand its maritime and naval capabilities. Better research infrastructure can support indigenous design, reduce dependence on foreign technologies and help build advanced marine systems within the country.
Role of Mazagon Dock Shipbuilders Limited
The facility has been developed with Rs. 4.5 crore in CSR funding from Mazagon Dock Shipbuilders Limited. MDL is a Navratna defence public sector undertaking under the Ministry of Defence and is one of India’s leading warship-building yards.
Mazagon Dock Shipbuilders has constructed 808 vessels, including 33 warships and 8 submarines. Its association with IIT Madras gives the project strong industrial relevance, especially in areas such as shipbuilding, defence technology and naval engineering.
This partnership is a strong example of how industry and academia can work together to build high-impact research infrastructure. CSR funding is often associated with social development projects, but this initiative shows that it can also support scientific infrastructure, advanced education and national technology development.
By funding the Circulating Water Tunnel Facility, MDL is contributing to long-term capability-building in a strategically important sector. The collaboration also aligns with India’s larger vision of Aatmanirbhar Bharat, especially in defence and maritime technology.
Benefits for students and researchers
One of the biggest advantages of the new facility is the opportunity it offers to students. For students in ocean engineering and related disciplines, the water tunnel will serve as a practical learning and research space.
They will be able to work on real-world problems in hydrodynamics, ship design, marine systems and underwater technologies. This kind of exposure is highly valuable for students who want to build careers in defence, shipbuilding, offshore engineering, research laboratories and maritime technology companies.
The facility will also support faculty-led research projects and doctoral studies. Researchers can conduct experimental investigations that may lead to better marine vehicle designs, improved propulsion systems and more efficient offshore structures.
In addition, such infrastructure can encourage interdisciplinary work. Students and researchers from mechanical engineering, aerospace engineering, applied mechanics, naval architecture and materials science may also benefit from the facility.
Strengthening India’s maritime ambitions
India has a long coastline, major ports, a growing naval sector and increasing interest in offshore energy and marine resources. To support this growth, the country needs strong research institutions and modern experimental facilities.
The new IIT Madras facility can contribute to this larger national goal. By enabling advanced research in ocean engineering and hydrodynamics, it can support innovation in shipbuilding, underwater systems, naval platforms and marine infrastructure.
The facility can also help improve collaboration between educational institutions, public sector companies, defence organisations and private industry. Such collaboration is essential for turning research ideas into deployable technologies.
Prof. Ashwin Mahalingam described the partnership with MDL as an important step in advancing research and technology development in ocean engineering and allied fields. He also highlighted that the facility will create valuable training opportunities for students and researchers.
Capt. Jagmohan noted that India’s maritime future depends on sustained investment in research, innovation and academic partnerships. According to him, the collaboration will support indigenous capability development and strengthen the vision of Aatmanirbhar Bharat in the maritime sector.
Future collaboration between IIT Madras and MDL
The Circulating Water Tunnel Facility may be only the beginning of a deeper partnership between IIT Madras and Mazagon Dock Shipbuilders. Both institutions are also exploring future projects in advanced maritime and naval technologies.
One proposed initiative is the HYDRA Centre, a large-scale hydrodynamic testing facility that could include a 500-metre towing tank. Such a facility would be useful for testing larger models and conducting more advanced experiments in marine hydrodynamics.
Another area under discussion is research on indigenously developed high-efficiency multistage thermoelectric subzero refrigeration systems. These systems could have applications in naval submarines and small vessels.
These future plans show that the collaboration is not limited to one laboratory. Instead, it could develop into a long-term research partnership focused on building indigenous maritime and naval technologies.
A major boost to India’s research landscape
With the launch of the Circulating Water Tunnel Facility, IIT Madras has added another important asset to India’s engineering research ecosystem. The facility will help strengthen teaching, research and experimentation in ocean engineering.
It will also provide students with hands-on exposure to real-world maritime challenges. For industry and defence organisations, the facility can support better design validation, technology development and collaboration with academic experts.
The project is also an example of how CSR-backed industry-academia partnerships can create long-term national value. By investing in scientific infrastructure, MDL and IIT Madras are helping build a stronger foundation for India’s maritime future.
As India continues to focus on self-reliance in defence, shipbuilding and advanced engineering, facilities like this will play an important role. The new water tunnel at IIT Madras is not just a laboratory; it is a platform for innovation, skill development and national capability-building.
