Notes:
These civilian ships were acquired to haul fuel-oil for the French Navy. They are capable of limited underway replenishment, and are manned by contracted civilian crews under a French Naval Reserve captain. The ships are operated under the banner of the Compagnie française des pétroles (CFP, marketed as Total S.A.). The 40mm gun is not mounted during peacetime, but can be installed during wartime as all fixtures are already in place.
