The Merchant Navy is one of the most promising career options for students who want a high-paying job, global exposure, and a professional life at sea.
In India, one of the most reliable ways to enter this field is through the Indian Maritime University (IMU), a central university under the Government of India.
This guide explains the complete process in a simple and clear way.
What Is IMU And Its Role
Indian Maritime University (IMU) conducts the IMU-CET (Common Entrance Test) every year for admission into maritime programmes across:
- IMU campuses
- IMU-affiliated institutes

This exam is the first and most important step.
