How to become a marine engineer

It can take several years to become a marine engineer as candidates might require education at a tertiary level. Employers might also prefer candidates with on-the-job experience from an entry-level role or internship, so it's often prudent to get some work experience while studying. The following steps can help you become a marine engineer:

1. Get a bachelor degree

Most engineers have a bachelor degree in marine engineering, offshore engineering or marine technology. General engineering degrees may also be appropriate if the candidate completes a work placement at a real-life company. Alternatively, hiring managers may also consider candidates who have obtained another science-based degree and have suitable work experience or a master's degree in a related field.

2. Consider a master degree

A master degree may be optional if you already have a bachelor degree in a specific subject for marine engineering. However, if you have a degree in another type of engineering, you might require a master degree that focuses explicitly on marine engineering. A master degree can also help you specialise in a particular area of marine engineering like submarines.
