Modification MMC definition: Also known as an Increase of Scope, this is defined as removing limitations previously placed on the credential such as change in horsepower, tonnage limitations, or geographic route.
Duplicate MMC definition: A replacement credential issued containing the same authority, wording, and expiration date as the lost or destroyed credential.
Document of Continuity definition: Documents issued solely to maintain an individual’s eligibility for renewal. The holder is not authorized to work under this document.
Be sure to select the appropriate Document of Continuity box under Transaction Type in Section II on page 3. Specify which endorsement(s) you want to put into continuity in the Description box on page 3. If you want all of your credentials to be placed into continuity, write "ALL CREDENTIALS HELD".
YOU MUST SIGN Section IV on page 4 that you are attesting to the statement: "I understand that a Document of Continuity is not valid for use in accordance with 46 CFR 10.227 and aware of the requirements to obtain an MMC. STCW endorsements may not be placed in continuity per 46 CFR 10.227."
STCW MMC definition: An annotation on an MMC that allows a mariner to serve in those capacities listed in 46 CFR 10.109(d) and serves as evidence that a mariner has met the requirements of STCW.
