Your all-in-one maritime companion

Chief Officer career path is one of the most sought-after progressions in the merchant navy, sitting just one step below the captain, the Chief Officer holds the most operationally demanding position on the deck side of any vessel. This guide covers the qualifications, responsibilities, salary, and advancement opportunities for those aiming to reach, or make the most of, this key rank.

What Does a Chief Officer Do?

the Chief Officer is the head of the deck department and the captain’s direct deputy. While the captain is ultimately responsible for the vessel, the Chief Officer manages the day-to-day running of deck operations with a level of detail and accountability that makes the role both demanding and rewarding.

Core responsibilities include:

• Cargo planning, loading, and discharge operations
• Ensuring vessel stability and trim at all times
• Overseeing all deck maintenance and preservation work
• Managing deck crew scheduling and watchkeeping rosters
• Serving as the primary safety officer (SOPEP, fire, LSA/FFA)
• Standing navigational watch (typically 4–8 and 16–20)
• Conducting crew drills, fire, abandon ship, man overboard
• Liaising with port agents, surveyors, and cargo interests

“The Chief Officer is where the real management begins,” says a veteran Master Mariner. “You’re responsible for the cargo, the crew, the stability, and the safety systems simultaneously. It’s the hardest rank on the ship.”

Qualifications Required to Become a Chief Officer

to sail as Chief Officer on an internationally trading vessel, you must hold a Chief Mate Certificate of Competency (CoC) issued under STCW regulations.

Educational Requirements

• Completion of a recognised maritime academy programme (BSc Nautical Science or equivalent)
• STCW Basic Safety Training (BST)

Sea Time Requirements

Before sitting the Chief Mate oral exam, candidates must have accumulated:

• Minimum 12 months sea service as an Officer in Charge of a Navigational Watch (OOW)
• Documented watchkeeping experience in the deck department
• Approved sea service on vessels of 500 GT or above (STCW regulation II/2)

Required Certificates and Endorsements

• Officer of the Watch (OOW) unlimited certificate
• Advanced Firefighting
• Medical Care on Board (MC)
• Ship Security Officer (SSO)
• Proficiency in Survival Craft and Rescue Boats (PSCRB)
• GMDSS General Operator Certificate (GOC)
• Radar / ARPA endorsements

However, vessel-specific endorsements, tanker, chemical, LNG, add significant value and open higher-paying opportunities.

Career Path: from Third Officer to Chief Officer

The typical route to Chief Officer in the merchant navy follows this progression:

1. Deck Cadet, First sea time, shipboard training record book
2. Officer of the Watch / Third Officer, First independent watchkeeping role
3. Second Officer, Typically responsible for charts, publications, and medical equipment
4. Chief Officer, Head of deck department, deputy to the Master

In addition, mastering the Chief Officer career path demands much more than sea time, the transition from Second Officer to Chief Officer requires not just additional sea time, but a demonstrable ability to manage people, cargo operations, and safety systems, skills that go well beyond navigation.

Key Challenges of the Chief Officer Role

Importantly, the role comes with significant pressure. Understanding these challenges before stepping into the position is essential:

• Cargo responsibility, Incorrect stowage or stability calculations can have catastrophic consequences.
• Crew management, Leading a multinational deck team with varying skill levels and language barriers.
• Documentation load, Port state control, ISM, SIRE, and company audits generate substantial paperwork.
• Watch burden, A 4-hour watch combined with daytime cargo operations frequently results in fatigue.
• Accountability, When something goes wrong on deck, the Chief Officer is first in line.

Advancing from Chief Officer to Master

The Master Mariner certificate is the next step for most Chief Officers. Requirements typically include:

• Minimum 36 months sea service as an officer on deck (of which at least 12 months as Chief Officer or OOW)
• Completion of a Bridge Resource Management (BRM) course and management-level STCW certificates
• Passing oral and written Master Mariner examinations
• Additional management-level training depending on flag state requirements

Notably, many Chief Officers spend several years consolidating experience before taking command, particularly on specialised vessel types where the stakes are highest.
