Samenvatting

As fuel is expensive and profit must be maximized, it is wise for the maritime industry to invest in fuel saving applications. One of the possibilities is to replace old turbochargers by new fuel saving ones on the already installed engines, recommended by Wärtsilä. Although the potential fuel savings claimed by Wärtsilä, only two out of five engines on board the m/s Oosterdam have received the upgrade. This raised the question if it is really that profitable to install the new turbochargers and thus the importance of this research was born.

The research-question was: “How much profit can be made within five years through saving fuel after installing new turbos on the diesel engines of the M/S Oosterdam?”, accompanied by three sub questions. The first: “What is the difference between the real Specific Fuel Oil Consumption of the engines with the new turbos compared to the ones with the old turbos?” Second: “At which load are the most running hours made?” and the third: After which period of time will the return on investment be made?

A quantitative research which assesses the SFOC of the engines which currently have the old and the ones with the new turbochargers has been conducted. Through this, the running hours per load and fuel prices, the potential profit for the next five years could be calculated. For the 12-cylinder engine it is commendable to perform the upgrade, but the 16-cylinder had little to no savings according to the data collected in this research.
