Abstract
Results of the simulation of and research into the cost effectiveness of mounting the turbogenerator on board a ship are dealt with in this paper. The analysis was performed by using the Konsberg NorControl crude oil carrier engine room plant, where the situations of the electrical power generation with turbo generator as well as with diesel generator were simulated. The initial cost analysis was carried out by a questionnaire with the exhaust gas boilers manufacturers, turbo generator and diesel generator suppliers. For the bunker price calculations, the present heavy fuel oil and diesel oil prices on the world market were used. The fuel savings were calculated by comparing the electrical power production situation with two diesel generators and the situation when a turbo generator was paralleled with a shaft generator. The results were additionally verified by using the computer aided program for the economical prediction of the project. The research results have arguably confirmed the thesis that mounting the turbogenerator on board a ship has great benefits and, if it is already mounted, it should be used as much as possible. The research results also confirm a great influence of planning the bunkering – choosing the bunkering ports, as well as the importance of the engine plant optimization and exploitation optimization on the final exploitation costs.
