How to Join Btech Marine Engineering

Following are the entrance exams that students must need to clear. TMISAT is a necessary requirement for joining B. Tech in Tolani Maritime Institute.

  1. IMU CET- IMU CET stands for Indian Maritime University Common Entrance Test. It is a common entrance exam for almost all IMU campuses and many other maritime courses. MERI Kolkata selects all its students on the basis of the result of their IMU CET ranking. 
  2. TMISAT- TMISAT stands for Tolani Maritime Institute Science Aptitude Test. Apart from clearing the TMISAT, candidates are also required to clear the IMU CET examination.

Once you have cleared IMU CET with a good rank then you will be shortlisted for the colleges according to your rank.

Rank Structure and Duties of the Engineering Department

Just like the Deck Department, the engine side comprises different ranks and posts dedicated to a variety of work. From engine room watches to steering, an engineer must be capable of everything. This is one of the reasons many people don’t go toward this profession as it requires rigorous hard work and patience.

Let’s look at the rank structure of Marine Engineers more closely.

Chief Engineer

Let’s start with the post at the pinnacle of the Engineering Department onboard.

The Chief Engineer is the head of the engineering department, commanding and maintaining the working of machinery parts of the ship falls under this post.

Chief Engineer must keep Master fully informed of all matters concerning the engine department that may affect.

  • Safety 
  • Navigation
  • Seaworthiness 
  • Cargo operations 
  • Efficient vessel operation
  • Environment  

To know about the duties of the Chief Engineer in detail, Visit this post:-
