What Does a Marine Engineer Do?

Find out what a marine engineer does, how to get this job, and what it takes to succeed as a marine engineer.

Marine engineers are responsible for the safe operation of marine vessels. They ensure that all equipment is functioning properly and monitor conditions like weather, currents, tides, etc., to make sure that their ship can safely navigate any waters it passes through.

Marine engineers may also be tasked with overseeing repairs or maintenance on their vessel. This includes everything from minor adjustments to major overhauls. In either case, they must ensure that all work is done in accordance with local and international safety standards.

Marine Engineer Job Duties

Marine engineers have a wide range of responsibilities, which can include:

  • Designing and testing new marine technologies such as engines, hull designs, or navigational equipment
  • Conducting inspections of ships for structural damage, seaworthiness, and safety issues
  • Monitoring engine performance and taking corrective measures if necessary to maintain efficiency and prevent breakdowns
  • Evaluating technical documents such as repair estimates, insurance claims, and salvage claims
  • Inspecting a vessel’s hull, machinery, equipment, and other components to ensure they are operating safely and efficiently
  • Inspecting crew working conditions to ensure they meet legal requirements
  • Installing and repairing engines and other equipment on board ships to ensure they operate efficiently and safely
  • Maintaining records of maintenance reports, repairs, and inspections performed on vessels
  • Planning, coordinating, and supervising the construction of new vessels, including establishing budgets and timelines for completion of each phase of construction

Marine Engineer Salary & Outlook

Marine engineer salaries vary depending on their level of education, years of experience, and the type of company they work for. They may also earn additional compensation in the form of bonuses.

  • Median Annual Salary: $85,000 ($40.87/hour)
  • Top 10% Annual Salary: $136,000 ($65.38/hour)

The employment of marine engineers is expected to grow slower than average over the next decade.

The need to update and maintain aging infrastructure will continue to support demand for marine engineers. However, automation and other technological changes are expected to reduce the demand for marine engineers.

Marine Engineer Job Requirements

Marine engineers typically need to have the following qualifications:

Education: Marine engineers typically need a bachelor’s degree in marine engineering, marine technology or a similar field. Some of the coursework these programs include thermodynamics, propulsion, propulsion systems, marine systems, marine engineering design, marine engineering materials, marine engineering systems, marine engineering design and marine engineering materials.

Many marine engineers also have an associate’s or a master’s degree.

Training & Experience: Marine engineers receive most of their training through formal education, but they may also receive on-the-job training to learn the specific requirements of their role. For example, a marine engineer working for a shipping company will learn how to calculate the weight of cargo and how to ensure that the ship is stable. A marine engineer working for a power company will learn how to ensure that the ship’s engines are running efficiently.

Certifications & Licenses: Marine engineers need a license to work on commercial or recreational vessels. Each coast has different requirements, but they typically include passing an exam and having at least four years of experience.

Marine Engineer Skills

Marine engineers need the following skills in order to be successful:

Technical skills: Technical skills are the knowledge and experience you have in a specific field. This can include knowledge of specific software, equipment and processes. Having strong technical skills can help you learn new skills more quickly and advance in your career.

Communication skills: Communication skills are necessary for marine engineers to have because they often work with other people, including other engineers, crew members and clients. Effective communication skills can help marine engineers explain technical information to others and collaborate with others to solve problems.

Problem-solving skills: Marine engineers use their problem-solving skills to identify and resolve issues with machinery and equipment. They also use these skills to troubleshoot problems with electrical systems, computer systems and other components of a ship.

Leadership skills: As a marine engineer, you may be required to supervise other engineers or technicians. Leadership skills can help you to manage a team and delegate tasks effectively. Leadership skills can also help you to motivate your team to work efficiently and to complete projects on time.

Teamwork skills: Working in a team can help you learn faster and complete tasks more efficiently. As a marine engineer, you may work with other engineers, ship captains and other professionals to ensure the safety of the ship and its crew.

Marine Engineer Work Environment

Marine engineers work in a variety of settings, including offices, research laboratories, and production facilities. They may also spend time on ships or other vessels, in shipyards, or at ports. They typically work full time, and some marine engineers may be on call 24 hours a day. Many marine engineers work more than 40 hours per week. Some travel may be required, particularly for those who work for consulting firms or who provide services to clients at their facilities. Marine engineers who work on ships or other vessels may be away from home for long periods of time.

Marine Engineer Trends

Here are three trends influencing how marine engineers work. Marine engineers will need to stay up-to-date on these developments to keep their skills relevant and maintain a competitive advantage in the workplace.

The Need for More Diversity in the Workforce

The maritime industry is facing a major diversity problem, as it is still very much dominated by white men. This is causing problems for the industry, as it is becoming increasingly difficult to find qualified workers who reflect the diverse population of the world.

Marine engineers can help solve this problem by becoming more involved in the hiring process and promoting diversity within their companies. They can also work to create a more welcoming environment for minorities and women, which will encourage them to pursue careers in the maritime industry.

The Importance of Cybersecurity

As technology becomes more advanced, so too does the need for cybersecurity professionals. Marine engineers are no exception, as they are now responsible for ensuring that the systems on board ships are safe from cyberattacks.

This trend means that marine engineers must be well-versed in cybersecurity techniques and technologies. They also need to be able to communicate with other members of the ship’s crew about how to protect against cyberattacks.

The Growth of Offshore Oil & Gas Exploration

Offshore oil and gas exploration is growing rapidly, which is creating opportunities for marine engineers.

As offshore drilling becomes more common, marine engineers will be needed to design and build the equipment used in these operations. They will also be needed to ensure that the equipment is operating safely and efficiently.

How to Become a Marine Engineer

A marine engineer career path can be rewarding and lucrative. It’s important to consider the many different specializations within this field, as well as the size of the company you work for. You may also want to think about whether you want to work onshore or offshore.

No matter which direction you choose, it’s important to stay up-to-date on the latest technologies and developments in your field. Networking is also key, so make sure to attend industry events and connect with other professionals online.

Advancement Prospects

Marine engineers and naval architects typically need at least a bachelor’s degree from an accredited engineering program to enter the profession. Many marine engineers and naval architects also get a master’s degree in engineering or a related field.

Advancement for marine engineers and naval architects generally comes with experience. Some may become technical specialists or move into management. With additional experience and education, marine engineers and naval architects may become licensed as professional engineers.
