Switching world shipping to marine diesel?

In 2006 CONCAWE published the results of a technoeconomic study analysing the impact of the reduction of the sulphur content of residual marine fuels (RMF) in Europe (CONCAWE report 2/06). The study contended that, when faced with a low sulphur limit on residual marine fuels, the most economically attractive alternative for refiners would be to exit that market and either convert or export the surplus residual material.
