NIT Calicut design and develop a 4kW deck power supply for Underwater ROVs

NIT Calicut has achieved a significant milestone in India's push for technological self-sufficiency by designing and developing a 4kW deck power supply for remotely operated vehicles (ROVs) used in underwater operations. This innovative product was handed over to the National Institute of Ocean Technology (NIOT) on March 14, 2025.

Prof. Prasad Krishna, Director of NIT Calicut, delivered the presidential address, emphasizing the importance of such collaborations in driving technological advancements and contributing to national interests. The proceedings began with a welcome speech by Dr. Raghu C V, Assistant Professor in the Electronics and Communication Engineering Department (ECED) at NIT Calicut. Dr. Nikhil S, Chairperson of CEVE, provided a technical description of the 4kW Deck Power Converter, highlighting its innovative features and potential applications in shallow water ROVs. This technology is expected to enhance the efficiency and reliability of underwater operations.

The 4kW power supply system, completely developed in India, operates on a standard 230V, 50Hz input and steps up the voltage to a range between 270V to 380V, with precise regulation at 290V. This is crucial for powering ROVs during deep-sea operations at depths of 500 meters.

A unique algorithm was developed to overcome the challenge of voltage regulation at extreme depths, ensuring consistent ROV performance without the need for ocean floor sensors. The power supply offers a cost-effective solution compared to international alternatives, without compromising on quality or performance.

The ceremony included the official technology transfer and release of the product manual, symbolizing the successful completion of the project and its readiness for deployment. Mr. Harikrishnan G, Scientist-F from NIOT, Chennai, addressed the gathering, expressing gratitude for the collaboration and highlighting the potential impact of this technology on NIOT's future projects. NITC student volunteers Muhammad Ali shafeeq, Ranjith G, and kannan SA were also part of this project.

This breakthrough is expected to significantly reduce operational costs for underwater ROVs and enhance India's ocean technology capabilities. NIT Calicut's development demonstrates the country's growing expertise in designing indigenous, high-performance solutions that meet international standards.
