The Merchant Navy is one of India’s most exciting and high-paying career options for students who dream of travelling the world while building a strong, respected career. If you’ve just finished Class 12 and are wondering how to join the Merchant Navy, this complete guide covers everything — eligibility, entrance exams, courses, salary, and the step-by-step roadmap to get started in 2026-27.
The Merchant Navy is the commercial shipping industry responsible for transporting cargo, oil, gas, and passengers across international waters. Unlike the Indian Navy, it is not a defence force — it’s a civilian profession under private or international shipping companies, though all operations are regulated by the Directorate General of Shipping (DG Shipping), Government of India, to ensure safety and compliance.

Step-by-Step Process: How to Join Merchant Navy After 12th
Step 1: Complete Class 12 with PCM
Ensure you clear Class 12 with Physics, Chemistry, and Mathematics, scoring at least 60% aggregate from a recognized board.
Step 2: Prepare for IMU CET (Indian Maritime University Common Entrance Test)
IMU CET is the most important entrance exam for admission into DNS, B.Sc. Nautical Science, and other officer-level courses at Indian Maritime University-affiliated institutes. This exam tests Physics, Chemistry, Mathematics, English, and General Aptitude.
Step 3: Apply & Appear for the Entrance Exam
Fill out the IMU CET application form and prepare strategically — securing a good rank is crucial, as it determines which institutes and shipping companies you’re eligible for.
Step 4: Sponsorship/Company Entrance Exams (Optional Route)
Many shipping companies also conduct their own sponsorship exams and recruit students directly, sometimes even before IMU CET results.
Step 5: Clear the Medical Examination
All candidates must undergo a thorough medical fitness test conducted only by DG Shipping-approved doctors. This is a mandatory and non-negotiable step.
Step 6: Counselling & Institute Selection
Based on your entrance exam rank and medical clearance, you’ll go through counselling and get admission into a DG Shipping-approved maritime institute. Always verify that your chosen institute is DG Shipping-approved — non-approved institutes can waste your time and money.
Step 7: Pre-Sea Training
This includes theoretical and practical training in navigation, ship operations, safety protocols (STCW courses), and simulator-based learning.
