| Summary: | This study concerns a model of the fuel consumption and emissions from the bottom longline fishing fleet at Rio de Janeiro State, Brazil with data comprised vessel and engine characteristics, fuel consumption, landings and fishing trip duration of seventeen longliners operating in Rio de Janeiro between 2015 and 2016. The operational pattern was investigated for this fleet, based on an empirical approach to model the propulsion power requirements of the typical longliner fishing vessel. The current propulsion and power plants of the longliner fishing vessels under consideration are compared with alternative designs by estimating fuel consumption for the different models of propulsion systems. When the operational pattern evaluation is taken into account, it indicates the future potential for diesel-electric propulsion for longliner fishing vessels, as a result of a reduction in fuel consumption. |
