Maritime, Marine & Shipbuilding Careers
Marine Engineering workers operate, maintain and repair propulsion, electrical and mechanical systems aboard vessels or in marine facilities.
What You Would Do
- Operate
- Maintain and repair propulsion
- Electrical and mechanical systems aboard vessels or in marine facilities
- Measure evaluate and document conditions against plans standards or requirements
- Read drawings procedures or technical instructions
- Prepare tools materials and the work area
The exact work depends on the employer, equipment, customer and specialty.
Types of Work You Could Explore
Engine-room watch — Inspect, test, repair or rebuild engines and their supporting systems.
Propulsion — Focus on propulsion within marine engineering work, using the tools and procedures required by the employer.
Generators — Focus on generators within marine engineering work, using the tools and procedures required by the employer.
Pumps — Focus on pumps within marine engineering work, using the tools and procedures required by the employer.
Refrigeration — Focus on refrigeration within marine engineering work, using the tools and procedures required by the employer.
Controls — Focus on controls within marine engineering work, using the tools and procedures required by the employer.
Maintenance planning — Focus on maintenance planning within marine engineering work, using the tools and procedures required by the employer.
Naval Architecture as a cross-listed design specialty — Focus on naval architecture as a cross-listed design specialty within marine engineering work, using the tools and procedures required by the employer.
You do not have to choose a specialty before you begin. Job titles and specialty names vary among employers and training programs, and one job may include more than one type of work.
Who Might Like This Career
This career may appeal to you if you are interested in engine-room watch, propulsion, generators. It can be a good fit for people who enjoy careful problem solving, accurate work, learning how equipment or systems behave and seeing a clear result from their effort.
Where You Could Work
ships, ferries, offshore vessels, shipyards, port facilities and marine engineering offices.
Work Conditions and Safety
Like many hands-on service careers, this work can involve hazards. The specific risks depend on the equipment, site and assignment. Training, safe work practices and protective equipment help workers do the job safely. New workers should perform unfamiliar or hazardous tasks only with proper instruction and supervision.
Pay and Job Outlook
Median annual pay: $109,530 in May 2025 for ship engineers.
These are national U.S. figures for the occupation or comparison group named above, not a promised starting salary. Pay can vary considerably by location, experience, specialty, overtime, union agreement, employer and service market. People starting the career commonly earn less than experienced workers; paid training programs may increase wages as skills grow.

- Read drawings diagrams procedures or technical instructions
- Use tools measuring devices and protective equipment correctly
- Inspect finished work and communicate problems clearly
How Marine Engineering Work Is Changing
Automation, sensors, digital work instructions, connected equipment, improved diagnostics and more detailed electronic records are changing the work. AI may assist with planning, fault isolation and documentation, while qualified workers remain responsible for safe decisions, physical execution and verification.
Software and AI may also affect scheduling, diagnosis, documentation, estimating, customer communication and the way workers receive technical information. The effect will vary by employer and specialty.
Much of the work still takes place in real buildings and field conditions, where workers must inspect, fit, adjust, test and make judgments based on the actual equipment. Skilled workers remain responsible for safe service and checking the finished work.
Education and Training
Preparation may include Registered Apprenticeship, employer training, CTE, technical or community college programs, manufacturer instruction, military experience and paid entry-level work. The best route depends on the occupation, equipment and local requirements.
Career Pathways and Apprenticeship Availability
Typical pathway: Established or clearly related apprenticeship routes are available.
Marine engineering pathways may combine sea service, approved training and employer development. Licensed duties require U.S. Coast Guard credentials; this career is cross-listed with Architecture and Engineering.
A Registered Apprenticeship follows an approved training plan and combines paid work, supervised learning, related instruction and progressive skill development. Some employers use the word apprenticeship for paid programs that are not registered. Ask the sponsor which type it is and what credential, wage progression and job it provides.
Licenses and Certifications
Employer qualifications, occupational certifications, equipment credentials, environmental or transportation rules, contractor licensing or other requirements may apply depending on the work and jurisdiction. Verify requirements before enrolling and ask whether training prepares participants for needed examinations or credentials. U.S. Coast Guard National Maritime Center

Career Pathways to Learn Marine Engineering and Gain Experience
Apprenticeship — Learn through real paid work with experienced workers who teach and guide you, supported by technical instruction and a structure for developing and measuring progress. Some apprenticeships are Registered Apprenticeships; others are not.
Entry-Level Jobs — Gain paid experience with tools, equipment, customer service, safety and workplace practices through beginning work in the field.
Youth Apprenticeship — Begin developing career skills through work while continuing high-school education where a suitable program is available.
Career and Technical Education CTE — Gain hands-on knowledge through a high-school or postsecondary program related to electronics, mechanics, construction, facilities, communications or service technology.
Pre-Apprenticeship — Learn introductory skills, safety and workplace expectations while preparing for apprenticeship or employment. Verify that the program connects participants with real employers and does not charge tuition simply for possible access to an apprenticeship.
Co-op — Combine education with career-related work experience through a high school, CTE program, community college or other educational program.
Paid Work-Based Learning — Get paid to do real work for an employer while learning skills and gaining experience related to the career.
Manufacturer or Industry Training — Learn a specific product, system or service method through employer-supported courses and credentials. This training often supplements rather than replaces supervised work experience.
From Learning to Experienced Work
Skills develop through practice and experience. People who are new to the work usually receive more instruction and supervision. As they demonstrate skill, judgment and reliability, they take on more difficult work, greater responsibility and more independent assignments.
A common progression: Learn → Practice → Gain Experience → Build Confidence → Take on More Responsibility → Work More Independently
Experienced workers may eventually supervise work or teach and guide newer workers, trainees and apprentices.
Where This Career Can Lead
With experience, you may specialize in more complex systems, become a lead technician, help train newer workers, or move into inspection, estimating, sales, project coordination, service management or business ownership where licensing allows. The realistic next step depends on the occupation, your experience, education and local requirements.
Questions to Ask Before You Apply
- Is this a paid job from the beginning?
- Is it a Registered Apprenticeship, an employer-run apprenticeship, another training program or a regular job with training?
- What equipment and work will I learn, and who will teach me on the job?
- How does pay increase as I gain skills?
- Who provides the classes, and can I earn college credit or an industry credential?
- What tools, transportation, physical requirements, licenses, background checks or costs should I expect?
