abstract

To support the propulsion and electrical requirements of an all-electric CVX, the use of heavy-duty power generation gas turbines could be considered as a viable alternative to conventional steam propulsion. A 300 MWe total plant baseload capacity is needed for an all-electric ship requiring 200 MWe for propulsion and a peak electric catapult power requirement of 200 MWe.

Applications of advanced marine gas turbines to provide electric power to an all-electric CVX have a major advantage in that the gas turbines do not have to be located in the same area as the electric propulsion motors. The possibility of locating the turbine-generators topside to minimize the ship impacts associated with long runs of large intake and exhaust ducts was briefly studied and is discussed herein.
