The paper is reviewing possible methods of electricity production on a handysize bulkcarrier with an electricity consumption at sea of ～ 400 kW. The choice of an optimum electricity production system for that type of ship has been based on economical and ecological aspects. It has been demonstrated that in view of the forthcoming strict regulations on SO_x emission levels, in Europe and worldwide it is not anymore prudent, to install on board a new built ship, 3 GenSets operating on HFO, as in harbours they have to be switched over to low sulphur fuels. The proposed instead set of one shaft generator and 2 GenSets operating on MDO proved (based on realistic costs) to be a best solution, rendering significant savings, and at the same time protecting the marine environment.
