Marine engineers apply engineering principles, such as computer science and electrical engineering, toward the design and operation of marine propulsion and onboard systems. This includes maritime power systems, control systems, and navigational frameworks for both surface ships and submarines. Pollution control and anti-fouling methods are important components of marine engineering.
