Marine Engineer

Marine engineers design and maintain the machines that power ships and boats. They work on engines, fuel systems, power generation and other equipment that keeps a vessel safe and running smoothly at sea. It's hands-on engineering that takes you out on the water or into engine rooms all over the world.

The role

What a marine engineer actually does, day to day.

As a marine engineer, you work on the machines and systems that keep ships running at sea. You might design a new engine that burns less fuel, create a waste system that keeps the ocean clean, or fix equipment that has broken down. Some of your time is in an office with computers and design software; other time you're on board ships or in workshops getting hands-on with machinery.

You'll work with naval architects (who design the ship's shape) and other engineers to solve problems. Ships face harsh conditions - salt water, storms, constant movement - so your machines need to be tough and reliable. You might spot a problem early and fix it before it becomes serious, or you might have to diagnose what went wrong and get it working again quickly. The work keeps you thinking hard about how to make systems safer and more efficient.
