A state's sealift capabilities may include civilian-operated ships that normally operate by contract, but which can be chartered or commandeered during times of military necessity to supplement government-owned naval fleets. Some smaller navies have built multi-role vessels that combine sealift with other capabilities, such as those of a patrol frigate or a command-and-control vessel, the Royal Danish Navy's Absalon-class and the Royal New Zealand Navy's multi-role vessel HMNZS Canterbury being examples.

Civilian use

Sealift refers to the re-supply of isolated communities with fuel, building materials, foodstuffs, vehicles and other goods. This is the most common method used for the coastal communities of northern Canada due to the lower cost and the larger capacity of ships and barges over aircraft. An annual occurrence in the Arctic, the sealift is usually performed between July and October, when the sea is ice free.

Typically two types of ships are used, the older, less-seen cargo ship and the more usual

forklift truck which is also carried on board. The interior of the barges are used to carry fuel and other supplies are carried in containers
on deck.
