The Marine Engineering and Research Institute (MERI), formerly known as the Directorate of Marine Engineering Training (DMET), now known as Indian Maritime University - Kolkata Campus and Mumbai Port Campus, is India's national institute and one of the institutes for the training of Marine Engineers and Polyvalent Officers.

Training
MERI has a workshop with machinery, equipment, steam engine and a diesel engine (Kawasaki-MAN, 6000 BHP) for training and to meet IMO and AICTE requirements. Students visit marine workshops for on the job training. Laboratories are provided for cadets/students to conduct practical experiments. Class rooms and teaching aids are in compliance with AICTE requirements. A new establishment for the training of cadets in basic firefighting is being set up in the campus and is projected to near completion soo. IMU Kolkata Campus now holds the honor of having a humongous working steam reciprocating engine by the efforts of the cadets and the workshop faculty itself who have restored the previously idle engine. It receives steam from a CT Package boiler, or a Foster Wheeler boiler that is independently fired and is capable of superheating the steam. The Ministry of Education and Culture accorded approval to the graduation certificate issued by the institution as being equivalent to a bachelor's degree in Marine Engineering with effect from 1980–1983 course for the purpose of recruitment to posts under the Central Government. The Graduation certificate issued by the institution received recognition from the Institution of Engineers (India) as an exempting qualification from their A and B examinations from 1982 onwards. The course has the approval of AICTE. In order to meet the IMO requirements for marine engineers working on board ship the training curriculum has been oriented to comply with the requirements of the STCW 95 convention. For quality accreditation, the institute is a certified ISO-9001 institute. It complies with the Indian Government's Right to Information Act.
