There were no serious injuries during the incident on board the Royal Fleet Auxiliary (RFA) support ship, which due to join this year's Carrier Strike deployment, although a spokesperson said local emergencies had been called as part of "standard protocol".
It follows reports from the Dorset Echo that four people were being treated for smoke inhalation by ambulance crews.
An MOD spokesperson said: "RFA Fort Victoria, currently in Portland, has this morning had a minor fire which was quickly extinguished by the ship's company. As is standard protocol in these situations, the local emergency services were called. There were no serious injuries."
The RFA is the Royal Navy's uniformed civilian branch supporting military operations and is staffed by merchant sailors.
RFA Fort Victoria and RFA Tidespring are set to join the Carrier Strike Group as replenishment vessels, supporting the other ships on the global deployment.
