Abstract
Abstract Due to new regulations about emissions, ship design needs to face in these years the challenge of implementing new technologies on-board vessels. All these technologies cut in different ways SOx, NOx and CO2 emission and affect different ship’s systems. Pollution reduction can be archived by implementing emission reduction systems, like scrubbers, or switching from traditional residual bulk fuels to different ones. To evaluate impact of each solution on-board, a system engineering approach must be applied since early-stage design. In this paper a simulation tool able to support ship design is presented. Thanks to a system simulation, different possible solutions for power generation are evaluated in three different cases, distinguishing specific weight factors for each evaluation criterion. Then, a rank of the different solutions is done in order to reflect the weight of the attributes in defining alternative layouts for the generation power plant.
