FEASIBILITY ANALYSIS OF SHAFT GENERATORS APPLICATION FOR OPTIMUM ELECTRIC POWER GENERATION AT SEA IN NEW BUILT SHIPS

The paper reviews and analyses today's applied and practically feasible method of electricity production onboard ships. Technical, economical and ecological aspects are taken into consideration in the selection of the optimum electricity generation installation. A revision of opinion on the unifuel ship concept is made in the light of the expected annex to Marpol 73/78 which will impose means of reducing air pollution from marine sources. The paper gives a thorough economical appraisal of various electrical power generation alternatives. Examples based on realistic data reveal the normally hidden investment costs as far as it concerns a classical diesel generator set delivered to a shipyard. If a price comparison is made between the investment cost of a HFO diesel generator (DG) set and a shaft driven generator of a hydro-mechanical option, the price gap, normally immensely exaggerated by the HFO DG protagonists, dwindles away to a figure allowing the recovery of the additional investment after approximately 3-4 years, this applies for cases where the required electricity production is in the range 300-600 kW, but for electrical powers exceeding 1000 kW the shaft generator is a cheaper solution.
