Preparation A high school diploma or GED is necessary for most jobs. Some stationary engineers learn their skills through an apprenticeship. Marine engineering plants are similar to many stationary power and heating plants. Working as a marine engineer for the Navy or merchant marines can provide a good background. The International Union of Operating Engineers sponsors apprenticeship programs.
Committees prefer applicants who have a background in math, computers, and mechanical drawing.
They also look for courses in machine-shop practice, physics, and chemistry. Mechanical aptitude, manual dexterity, and good physical condition are also important. An apprenticeship usually lasts four years. Apprentices receive 8,000 hours of on-the job training and 600 hours of classroom instruction. They study boiler design and operation, basic chemistry, and water treatment.
