Hello Prashant

This is Simran Pal, from Careers360, I am hoping I can solve your query.
You havent mentioned your desired location.

The birth of Indian Maritime University is a long cherished dream of the maritime community of India.

The Indian Maritime University came into being through an Act of Parliament (Act 22) on 14th November 2008 as a Central University and is poised to play a key role in the development of trained human resource for the maritime sector. 14th November is celebrated as 'IMU Day' every year.

The following are the objectives of the University: 

(i) To facilitate and promote maritime studies, training, research and extension work with focus on emerging areas of studies like oceanography, maritime history, maritime laws, maritime security, search and rescue, transportation of dangerous cargo, environmental studies and other related fields, and also to achieve excellence in these and connected fields and other matters connected therewith or incidental thereto.
IMU CET is one of the premier exams that students take who wish to enroll in various courses of the institute.
 

To know more about the courses, I would suggest you check out the website and contact the authorities who will be able to explain the whole thing in a much professional manner.

I hope this helps,

All the best!
