Guide to Merchant Navy Ranks
Being in a job that requires high professionalism, any mishap can have serious consequences, hence the need for a Marine rank system to ensure a smooth and efficient workflow. The Navy's rank system establishes etiquette rules, a sound framework, and facilitates ease of learning for beginners, promoting effective communication between different departments, and more.
Since seafarers come from all over the world and sail around the world, it is important to have a globally recognized Merchant Navy rank. This ensures better coordination among sailors while issuing and executing different levels of commands. The pride, responsibility, and uniforms of different naval ranks still attract many sailors to choose it as their preferred career.
Depending on the commanding ship and shipping company, the positions and jobs assigned to a particular rank holder may vary. Generally speaking, the work of a ship is divided into three subsections:
Deck Section
When any individual is assigned a task, either on deck or in the engine section, the crew is divided into two groups to complete the task to the best of their ability, and these two groups are:
Officers

The First Mate is responsible for numerous other duties on board the ship, including operating the firefighting system, security equipment, and accommodations. Additionally, various land-based operations, including cargo preparation and docking, are conducted under the supervision of the First Officer.
The First officer is usually so busy with shore-based shipping operations that he does not have enough time to perform port watch duties. However, he performs safe navigation shifts on board the ship between 4:00 a.m. and 8:00 p.m. and between 4:00 p.m. and 8:00 p.m.

From here, we can see how the Navy completes the complex operation of ships safely and efficiently through the division of ranks.
Hierarchy of the Engine Department of Merchant Ships
1. Chief Engineer
The Chief Engineer is the head of the engine department of the merchant fleet. He is in charge of the engine department. The Chief Engineer implements strict regulations on the management of ship machinery pollution. It also monitors the auxiliary machinery of the ship and tracks the performance of the main propulsion system. He submits regular reports to the company headquarters on fuel supply operations, fuel, lubricants, other fluids, etc.
The Chief Engineer reports any type of machine damage or any other technical problems that may arise.
2. Second Engineer
The Second Engineer assists other junior engineers in the daily work of the engine department and undertakes the special task of training engine trainees in ship machinery. The Second Engineer often patrols the engine room during the day. With the assistance of the Fifth Engineer, he is also responsible for documents, photocopying, and laminating. A highly skilled and professional Second Engineer is the core of the engine room.
If he possesses good troubleshooting and leadership skills, the engine room workers will have a positive experience.
3. Third Engineer
In addition to daily rounds in the engine room, the Third Engineer is also responsible for checking the machinery under the supervision of the Chief Engineer. The Third Engineer assumes responsibility for the furnace room, boilers, and auxiliary machinery. Generally, the Third Engineer is also responsible for the boilers and auxiliary engines. The Third Engineer is also responsible for managing all pump lines, emergency pump lines, refrigerated catering boxes, spare parts, and ship stores.
Generally, the duties of the Third Engineer vary from company to company and are clearly documented in the company's safety management system .

He is one of the most important people on board. He is concerned with the electrical and technical aspects of the ship. Advanced Unmanned Ships (AUS) have a special requirement for electricians, as these ships require a significant amount of power and computer-controlled machinery. As automation becomes increasingly important in ship operations, the role of electricians is also becoming more significant.
7. Installation Technician

Installation is an art, and a skilled technician is proficient in it; therefore, the work becomes easier under their supervision.
