How to become an Ordinary Seaman

An Ordinary Seaman (OS) is a deck crew member on a merchant ship. OSs perform general maintenance, cleaning, and watch-keeping duties. They are also responsible for the safety of the ship and its crew.

Becoming an OS requires little formal education or training. Most OSs are hired directly out of high school or after completing a short training course. There are no specific requirements to become an OS, but most employers prefer candidates who have some experience working on boats or in the maritime industry.

Once hired, OSs typically undergo a brief period of on-the-job training. This training covers topics such as safety procedures, firefighting, and basic maintenance tasks. After completing their training, OSs are responsible for their assigned duties and work shifts.

Working as an OS can be challenging but also rewarding. It is an excellent way to learn about the maritime industry and gain experience working on ships. For those interested in a career at sea, becoming an OS is a great first step.
