Detailed Guide for

Ship Engineers in San Diego County

May also be called: Deck Engineers; Deck Officers; Engineering Officers; Marine Engineers; Operating Engineers

What Would I Do?

Ship Engineers make sure that cargo and passenger vessels are mechanically sound. To do this, they operate, maintain, and repair engines, boilers, generators, pumps, and other machinery aboard both sea-going and inland water vessels. Four types of engineering officers are customarily found on merchant marine vessels: Chief Engineers and First, Second, and Third Assistant Engineers. In addition to their more specific duties, Assistant Engineers stand assigned watches, overseeing the safe operation of engines and machinery.

Chief Engineers are responsible for all the propulsion machineries, power generating equipment, and auxiliaries. They maintain documents pertaining to the working of the machinery as well as all repairs done. Chief Engineers keep logs of fuel consumption and fuel requirements.

First Assistant Engineers are responsible for the maintenance of lubricating systems, engine room auxiliaries, and electrical equipment.

Second Assistant Engineers are responsible for fuel and water supplies. They supervise fuel and water tank soundings and monitor boiler room equipment.

Third Assistant Engineers are responsible for the operation and upkeep of engine room auxiliaries.

Ship Engineers employ a wide variety of tools and equipment in the course of their duties, using control mechanisms, direct physical activity, or computers to operate machines or processes. They may operate auxiliary power plant equipment, lathes, power generation equipment, a variety of machine tools, acetylene welding/cutting torches, engine diagnostic equipment, hand or power tools, pneumatic tools, precision measuring devices in mechanical repair work, two-way radio or mobile phone, weighing or measuring devices in transportation.

Working Conditions

Life aboard ship has been made more pleasant with air-conditioning and comfortable living quarters. The availability of e-mail service also helps to keep up morale aboard ship as Engineers are able to keep in touch with their families and friends during long voyages. However, Ship Engineers are away at sea or other waters for long periods of time and in all weather conditions.

Potential hazards associated with working on a ship include abandoning the ship in an emergency and working with machinery, heavy loads, and dangerous cargo. The implementation of uniform international regulations has raised shipping standards concerning safety, training, and working conditions, thus decreasing on-board injuries and fatalities.

Ship Engineers may work seven days a week especially on long voyages. They usually stand watch for 4 hours and are off for 8 hours. Workers on rivers, canals, and in harbors are likely to work year-round. Some work 8- or 12-hour shifts and go home every day. Others may work for a week or month and then have an extended period off. Their shifts are usually 6 or 12 hours, and then they are off for 6 or 12 hours.

Unionization of Ship Engineers is common, and they may belong to one of the following unions: American Maritime Officers, International Organization of Masters, Mates, and Pilots, the Seafarers’ International Union of North America, or the Marine Engineers’ Beneficial Association.

Will This Job Fit Me?

The job of Ship Engineer may appeal to those who enjoy activities that involve practical, hands-on problems and solutions and, to some extent, those who enjoy activities that involve leading people and making many decisions.

How Do I Qualify?

Education, Training, and Other Requirements

There are basically two ways to gain the education and training needed to become a deck officer or Ship Engineer. Those considering the occupation must either build up thousands of hours of experience in the engine department of a ship, or graduate from the U.S. Merchant Marine Academy or another maritime academy. In either case, applicants must pass a written test. It is hard to pass the test without a great deal of formal schooling or independent study. The academies offer a four-year program leading to a bachelor-of-science degree, a license (issued only by the Coast Guard) as a third mate (deck officer) or Third Assistant Engineer (engineering officer), and (if the person chooses) a commission as ensign in the U.S. Naval Reserve, Merchant Marine Reserve, or Coast Guard Reserve. With experience and additional training, third officers may qualify for higher rank. Generally, officers on deep water vessels are academy graduates and those in supply boats, inland waterways, and rivers rise to their positions through years of experience.

The only U.S. Merchant Marine Academy is located in Kings Point, New York. The California Maritime Academy, located in Vallejo, is the only degree-granting maritime academy on the West Coast.

The academies offer a four-year academic program leading to a bachelor of science degree, a license (issued only by the Coast Guard) as a Third Assistant Engineer, and, if the person is qualified, a commission as ensign in the U.S. Navy Reserve, Merchant Marine Reserve, or Coast Guard Reserve.

Federal regulations require that the job applicant pass a physical examination, a drug screening, and a National Driver Register Check before being considered for employment.

Early Career Planning

High school students interested in this type of work should take coursework in mathematics, science, electronics, computer technology, language arts, machine shop, and auto shop. Students who are interested in water transportation occupations might consider participating in a local Sea Scouts troop. Sea Scouting is a part of the Venturing program that the Boy Scouts of America offers for young men and women. This organization teaches high school students (ages 14-20) basic sailing and shipboard tasks on working ships throughout California, including inland ports on rivers and lakes.


Workers on ocean-going or Great Lakes vessels need occupational specialty licenses, issued by the U.S. Coast Guard, to work as engineering officers, or deck officers. Those seeking licenses are required to obtain and carry a Transportation Worker Identification Card, for which applicants must be fingerprinted, provide proof of citizenship, and possess a valid Social Security number. Applicants must also undergo a physical exam and submit to a drug test.

Where Can I Find Training?
