Hi,
First of all : You need to have either of the two qualifications :
A degree in Mechanical engineering OR 10+2 PCM >60%.
Then you can either chose to be a officer in the deck dept or a engineer officer.
For deck department :
You need to undergo a 3 year nautical science course followed by 12 months of sea service. Post that you need to appear for MMD oral examinations to get your first license as a officer : Second mate of a foreign going ship. By the time you reach this stage you will know exactly how to proceed further.
For engine department : Procedure is similar to deck dept but the courses/duration may be different.
