The objectives of this project were to characterize the vessels that comprise the New York City (NYC) harbor private ferry fleet, select technologies with the potential to reduce exhaust constituents, and to demonstrate selected technologies on representative vessels to determine their effectiveness. In order to complete these objectives it was first necessary to characterize the NYC harbor private ferry fleet with regard to vessel type, passenger capacity, installed power, propulsion system, fuel, fuel consumption, operating profile and emissions signature. It was determined that the ferry fleet and its subsequent emissions could effectively be classified according to the scheduled routes and modes of operation. The routes were classified as short, intermediate and long haul with single leg distance being the determining factor. Additionally, three different modes of ferry operation were identified: cruise, push, and maneuvering. |
