A liquefied natural gas carrier uses a diesel engine or gas turbine propulsion plant fitted with a shipboard regasification system. The propulsion plant can provide either a direct mechanical drive of the propeller shaft and propeller, or can be fitted with an integrated electric power plant using an electric motor or motors to drive the propeller shaft and propeller. The regasification system includes a heat input source of exhaust gas heat exchangers, electric water heaters and supplemental heaters to provide an additional heat source to a hot water circulating loop. The liquefied natural gas contacts the hot water or heating medium circulating loop and is regasified. An undersea conduit from the ship transmits the regasified natural gas to an on shore plant.
