I came to Chennai for repairing ships in harbor for a company called Binny Ship Repairs in Chennai Harbour. It was in 1981 after my B Tech in Naval Architecture and Ship Building. I joined as a Senior Project Officer in IIT Madras leaving my ship repair job. On completion of the project I could complete my MS too. Then I joined NSTL Visakhapatnam as Scientist. I was lead in installing the towing ccarriage in the high speed towing tank of NSTL, Visakhapatnam, Asia’s biggest facility with length 500m, breadth 8m and depth 8m. I was awarded prestigious ‘Monbusho’ scholarship of Japanese Govt. for doing Ph D in Yokohama National University, Japan.(1991-1995). Therafter, I joined NIOT, Chennai as Visiting Scientist and worked for 15 months. Given below is some details of my professional experience.
June 2018- Till date: Professor in HAG grade. Research, teaching and consulting. Member of the selection committee in faculty recruitment since 2019, onwards.
Jan 2010 –May 2018: Working as Professor, in Dept. of Ocean Engineering, IIT Madras. Also active member in Researchgate and Linkedin .
Teaching, consultancy and research in marine transportation, modernization of inland waters, application of composite and light materials to ship hulls are main attention.
In the recent past attention was on research on ship motion and control. The targeted ships are large ones VLCC(Very large crude carrier), ULCC(Ultra large contained carrier), Very large bulk carrier , LNG ships etc. Double hulls are considered with special interest.
Structural components are paid attention. Fatigue, corrosion, fracture, coating etc. are considered. Composite material are also included in the research. An international advisory board of MARTEC 2016 to be held in Dhaka, BUET of Bangladesh.Has been serving since 2006, as Editorial Board member of International Journal of Ships and Offshore Structures, Taylor and Francis. Actively support the journal by review and academic circle contacts.

Taught ship theory and Naval Architecture in Busan National University for 16 moths during the Visiting Professorship period in Korea. Was invitee two times spanning two years plus for the prestigious Brain Pool and Brain Korea research Program.
I am rated to be very good teacher continuously by student community of IIT Madras.
Guided UG students for their projects. M. Tech students, MS students and Ph. D scholars. Taken up consultancy services for new shipyard setting up, ship yard modernization, new tug berth design and vibration analysis of ship structures. Taken up experiments on moored floating bodies in wave basin based on a design from a USA firm. Nine designs for hull in FRP have been completed for modernizing the transportation in the inland waterways of Odisha. New ones are initiated to help the rural community of Odisha by modernising their inland waters with better hulls. Always keen to keep an uncompromising edge over the conventional practice in of marine technology.
Nov. 1996 –May 2010: Involved in active teaching. Worked as Asst. Professor and then as Associate Professor in the Ocean Engineering Centre of IIT Madras. Involved in teaching UG students. Handled subjects mentioned above like computer aided ship design and drafting, ship powering and resistance, ship maneuvering, marine engineering, ship hydrodynamics etc.
Sept. 1995 to Sept 1996: Working as Visiting Scientist, at NIOT, Madras. Designed floating bodies and associated structures meant for tapping wave energy. Worked out the dynamics of concrete caissons towing in sea just before the installation. Worked out the feasibility of caisson towing alone and the construction of caissons on board a barge and towing it to the required site, installation, erection etc. Worked out the hydrodynamics as well as the structural dynamics of towing systems.
Oct. 1991-Mar. 1995: Was working for the Ph. D in Ocean Engineering at the Design dept. of Yokohama National University, Japan. Developed, modified and handled many computer codes in UNIX environment. Got hands on experience in computer aided design and proposed certain innovations for users in Naval Architecture.
Developed and handled software package programmes meant for structural, ship and floating platform design. Got specialization in dynamics of towing and mooring. Suggestions in view of the recommendations of SOLAS Chapter V were made. This is relevant to the latest emergency towing arrangements on board tankers. Various charts connecting line length, mean pull and line diameter were presented in the meeting of JSNA (Japanese Society of Naval Architects, Tokyo) and then later published in its journal in 1994. Many researchers used my results for their further works on towing. Citations seen in the reputed international journals are proof for this. The complicated problem of sea bottom interaction of mooring chain was solved using a mathematically efficient approach. It was based on a lumped mass system and finite difference approach.
July 1990- Sept. 1991: Served as Scientist -C (Senior level in DRDO, Ministry of Defense,
Government of India) in Naval Science and Technological Laboratory of Visakhapatnam. Was head of ship model making facilities. Was responsible for the maintenance and utilities of ship model milling machine, copy milling machine and other machines in the workshop. Ship models were made from wax, softwood and fiber-reinforced plastic. Have complete know-how of model making using fiber-reinforced plastic. Was also responsible for trials of model testing and carried out maintenance and trial running of towing carriage. The physical description on this is given in the following two paragraphs.
Sept. 1984- June 1990: Served as Scientist -B in Naval Science And Technological Laboratory, Visakhapatnam, Govt. of India. Was responsible for the erection, installation and assembly of High Speed Towing Tank (Length = 500 m, Breadth = 8 m and depth = 8 m.). This facility is the biggest in its kind in South East Asia. Erection and Installation was done in consultation and association with the technocrats of M/s Kempf and Remmers of Hamburg, West Germany. Have done the erection and installation of current conductors at a height of about 6 m above the corridor level. Fabricated carriage parts, assembled and installed.
March. 1982- Sept. 1984: Served as Senior Project Officer at Ocean Engineering Centre at IIT, Madras, India. Was responsible for the design of underwater vehicles and cables for the same. Identified the basic causes of kiting or tow-off associated with the cable- body system. Remedies were suggested for this problem.
Sept. 1981- Feb. 1982: Served as a Management Trainee at the harbor works of M/s Binny Engg. Ltd, Madras Harbour, India. Done repair works of hull, deck and machinery of bulk carriers.
