System simulation as decision support tool in ship design

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