Ship Officer Ranks: A Guide for New Mariners

Hi everyone! I’m a 3rd Mate and thought I’d use my downtime to write some guides for cadets. Back in high school, I kept a notebook of all my questions about life at sea, and I want to share the answers I’ve found. Hopefully, this helps future mariners get a head start without upseting too many of the old salts here!

First 1010 topic. Ship officer ranks!

If you’ve just graduated from a maritime academy or are considering a career at sea, understanding the various ship officer ranks is crucial. Whether you’re a deck officer or an engineer, the rank structure on board a vessel dictates everything from responsibilities to career progression. Here’s a breakdown to help you navigate your way through the ranks.

1. Deck Officers: Navigators and Leaders

The deck department is responsible for the ship’s navigation, cargo operations, and overall safety. Here’s the typical hierarchy:

  • Third Mate (3/O): Often your starting position right out of maritime college. Third Mates focus on safety equipment, navigation, and watchkeeping.
  • Second Mate (2/O): With more experience, you’ll move up to this rank, where you’ll handle navigation planning and oversee loading and unloading operations.
  • Chief Mate (C/O): The Chief Mate is second in command after the Captain. They manage the deck crew, cargo operations, and are the go-to for shipboard training and safety drills.
  • Captain (Master): The Captain is in ultimate command of the vessel, responsible for the ship, crew, cargo, and compliance with maritime regulations.

2. Engineering Officers: Powering the Ship

Engineering officers ensure the ship’s machinery and engines run smoothly. Their hierarchy is:

  • Third Engineer (3/E): Entry-level role for engineering graduates, focusing on the engine room’s auxiliary systems.
  • Second Engineer (2/E): Oversees the daily operation and maintenance of the main engines.
  • Chief Engineer (C/E): The head of the engineering department, responsible for all engineering operations on the ship.

Overall in charge of the ship is the Master (or Captain).

In the US we call deck officers mates, but o erseas they are often called officers. So a Second Mate is really the same thing as a Second Officer. Both are deck officers.

3. Earning Your Stripes: Education and Experience Matter

Becoming a ship officer isn’t just about attending a maritime college. It’s a combination of education, sea time, and exams. For example, according to some, the path to higher ranks can vary based on your choice between the “hawsepipe” route (climbing up from unlicensed positions) and a formal maritime academy education. Outside the US the hawsepipe route is still viable but here the unlicensed unions have very few scholarships to advance to officer… which requires lots of maritime traning.

Advice for New Mariners: Building Your Career

Stay curious and committed to your career path. It’s good to constantly upgrade your skills and certifications, be it through your company or union. Some new officers might find it challenging to get support for training from their employers, so it’s essential to seek out opportunities proactively. Networking and staying informed about industry changes are crucial for career growth.

Understanding the ranks is just the beginning. Keep asking questions, seek mentorship, and remember, every Captain and Chief Mate started where you are now.

This is easier on some ships than others depending how busy you are. A great way to learn about the industry is just to take classes at a union school. I often earned more hanging out in local bars and by the pool with older mariners than sitting in the classroom.

Cruise Ship Deck Officer Ranks

Cruise ship officer ranks are structured a little different from other merchant vessels but have their own unique distinctions given the hospitality aspect of the industry. The hierarchy starts with the Captain (Master) , who has overall command of the ship and is responsible for the safety of passengers, crew, and the vessel.

Below the Captain is the Staff Captain , who acts as the second-in-command and oversees the ship’s operational departments, such as the deck and engine departments.

Next is the Chief Officer (Safety Officer) , responsible for the safety and security of the vessel, followed by other deck officers like the Second Officer and Third Officer , who manage navigation and safety duties.

Cruise Ship Engine Officer Ranks

The engineering department has a similar rank structure, led by the Chief Engineer , who is in charge of all technical operations, supported by the Staff Engineer , First Engineer , and other subordinate engineering officers.

Additionally, cruise ships have a separate hierarchy for the hospitality side, managed by the Hotel Director and supported by various department heads like the Chief Purser and Cruise Director , reflecting the unique blend of maritime operations and hospitality services on these vessels.

Nice! Thanks for putting this together Trent. Looking forward to reading more. I get emailed a ton of really basic questions so it’ll be nice to have links I can email back to young people

These aren’t the names we use for engineering licenses or positions in the US.

My ship does but they’re abbreviate differently. Also, the OP is missing the most important person on the engineering team of the FIRST ASSISTANT ENGINEER. If there’s no 1AE, & it goes Chief to 2nd Engineer, then who fills in the gaps of knowledge the CE forgot & the 2A/E doesn’t know yet? BTW, abbreviations we use are CE, 1AE, 2AE & 3AE.

No, you use the American system.

That’s the Second Engineer.

That’s the Third Engineer.

I work on a 30+ year ship & I’ve seen the COI. My predecessors used the position names on the original COI & everyone else just continued. Call those old COI positions, US, American or Klingon, I don’t care as long as my pay is correct & on time.

If it was issued by the USCG then it uses the American position names. A modern American vessel’s COI still uses the American names for the engineers so I’m not sure why the age matters.

The crew lists internationally are in English and list the second engineer and third engineer and so on down. I sailed with an engineer that had been the second acting seventh onboard the old Queen Mary.

He’s not. In STCW and generally outside the US the 1st AE is the “Second Engineer.” See e.g. the definitions of “First Assistant Engineer” and “Second Engineer Officer” in 46 CFR 10.107 (they’re the same).

In the USA this is called the First Assistant Engineer.

Known to the US as the Second Assistant Engineer.

I hear those terms on the US flagged tanker I work on all the time.

Also often hear 3rd/2nd/1st assistant.

I say so and so “engineer” without the “assistant” all the time.

I also say so and so “assistant” without “engineer” all the time.

Both are correct and acceptable.

Yes, we get lazy all the time and call the “First Assistant Engineer” the “first assistant” and “first engineer” all the time. Same goes for the “second assistant engineer” being called the “second assistant” and “second engineer” onboard, and we know what we’re talking about. That doesn’t change the fact that the First Assistant Engineer is the Second Engineer in the nomenclature used by the rest of the world (and on their STCW management level document).

But they mean different things, which I have repeatedly pointed out, and you’re just ignoring.

The definition for both in 46 CFR 10.107 is verbatim identical.

I was referring to how we frequently refer to the Second Assistant Engineer onboard as the Second Engineer and how those two things don’t actually mean the same thing.

But they do on your ship.

I will refrain from providing a full critique, as I have experienced the odius nature of these fora previously. However, I will point out two of your many errors. AB does not mean Able Bodied Seaman. Although this, like all of your errors, is politically correct (I can explain what politically means, if you’re interested - which I doubt) it simply means, Able Seaman. The abbreviation is derived from the first two letters. You can look it up. But if you do, stick to the government publications where you can get the straight goods.

Your unforgivable error is in classifying the Master (Captain) as a “Deck Officer”. The Captain is IN COMMAND of the ship - the whole ship - not just the deck - not just the bridge - THE WHOLE SHIP. He, alone, is in charge. I have spent most of my working life in that position and I can tell you that there is nothing worse than being undermined in even the slightest way.

Unless you wish to live out your life as a non-contributor, never accept anything without question.

Some offshore vessels have the extra rank of First Officer (1/O).

They can have 3/O, 2/O, 1/O, C/O and Master.

A 1/O is essentially a 2/O who is the SDPO if the Master doesn’t keep a regular watch. So you would have the C/O and a 2/O on one watch and the 1/O and a 2/O on the other watch.

Also Scandinavians call a 2/O a 1/O which makes things a bit more confusing.

Well, since we’re in the spirit of pointing out errors, let me ask you, why exactly did you reply to me? I didn’t type the words, AB, Captain, Master or about anything else you supposedly corrected me on.

But your error isn’t unforgivable. I hereby declare you forgive captain, master but not deck officer.

Sorry, Mate. I was attempting to reply to the original post. My goof.
