FCC Commercial Operator License Program

You need a commercial operator license to operate, and/or to repair and maintain, specified ship, and aircraft radio communication stations. The licensing requirements for operating such radio stations and the licensing requirements for repairing and maintaining such radio stations are discussed separately below.
You need a commercial radio operator license to operate the following:
Ship radio stations if:
the vessel carries more than six passengers for hire; or
the radio operates on medium frequencies (MF) or high frequencies (HF); or
the ship sails to foreign ports; or
the ship station transmits radiotelegraphy; or
the ship is larger than 300 gross tons and is required by law to carry a radio station for safety purposes.
Aircraft radio stations, except those which operate only on very high frequencies (VHF) and do not make foreign flights.

Years ago I took and passed the tests for the GROL and GMDSS as well as others. How would I find these records after 30 yrs? I have searched the FCC database for them with my personal FRN but no luck. Thanks.

I would reach out to the FCC. That have updated their record keeping and license types quite frequently over the last 30 years. Likely they have your license on record somewhere but I cannot guarantee that they wont require you to complete a new course or exam to operate the same type of equipment that you were certified before. hope that makes sense.
