How do I get my Ordinary Seafarer rating?

An ordinary Seafarer (OS) is the lowest rating on a ship. This is an unlicensed position, and it requires no maritime experience. Ordinary seamen handle a variety of basic tasks, working towards becoming an Able Seafarer.

The first step you need to take is getting a valid U.S. Merchant Marine Credential (MMC).

You need to take care of these 6 easy steps to get your entry level MMC:

1. You must be a US Citizen or alien admitted for permanent residence
2. Hold or have applied for a TWIC
3. Be at least 16 years old (with parental/guardian consent if under 18)
4. Pass a drug test within 6 months (CG-719P)
5. Must hold or be approved for Medical Certificate (CG-719K or CG-719KE)
6. Pay Mariner's Fees (pay.gov)
   

Once you've completed those items, you'll complete and submit a CG-719B form. This is the MMC application form.

Note: Getting your MMC is not a guarantee of finding work. This is a certification that allows you to work in the professional maritime industry.

Ordinary Seafarer duties and responsibilities

Ordinary seamen are doing most of the grunt work around the ship. It's not glorious, but it's the path forward to becoming a licensed Able Seafarer in the future. OS responsibilities include general maintenance, cleaning and sanitizing the ship, painting, loading and unloading cargo, and more.

As you gain more experience, you can expect more responsibilities.

How many Sea Days are needed?

There are no sea service requirements for entry level endorsements. Employers will typically want you to complete some basic maritime training before you start working.

What endorsements are included in an Entry Level Rating?

Ordinary Seafarer, Wiper, and Steward’s Department (FH).
