Alternative fuels and fuel-flexible ships are often seen as promising solutions for achieving significant greenhouse gas reductions in shipping. We formulate the selection of alternative corresponding ship power systems a bi-objective integer optimization problem. apply our model to Supramax Dry-bulker solve it lower bound price scenario including carbon tax. Within this setting, question wheth...
