Abstract

Energetska učinkovitost i ekološka prihvatljivost broda postale su bitni parametri pri projektiranju brodova. Također, Međunarodna pomorska organizacija daje sve veću pažnju smanjenju ugljičnog otiska pomorskog prometa. Poseban naglasak je na proučavanju brodova koji plove u priobalnoj plovidbi jer plove u blizini naseljenih područja i imaju perspektivu za smanjenje ugljičnog otiska uzimajući u obzir njihove operativne režime. U priobalnoj plovidbi plovi i veliki broj ribarskih brodova. Cilj ovog rada je idejno rješenje elektrifikacije plivaričara sa svrhom povećanja energetske učinkovitost broda, i smanjenja ugljičnog otiska. Elektrifikacija ribarskih brodova u samom je začetku te su se posljednjih godina tek počeli graditi elektrificirani ribarski brodovi. Analizirajući potrošnju goriva sličnog plivaričara te tipične operativne režime odabranog plivaričara utvrđeno je da postoje predispozicije za ugradnju hibridnog energetskog sustava koji bi povećao energetsku učinkovitost broda te smanjio ugljični otisak. Nadalje, u radu je ponuđeno idejno rješenje hibridnog energetskog sustava s dizel generatorima i baterijama te elektromotorom koji pokreće brodski vijak. Izložena je energetska bilanca idejnog hibridnog rješenja te režimi rada. Na kraju je provedena analiza cjeloživotnih troškova za postojeće energetsko postrojenje plivaričara i za hibridno te su uspoređeni dobiveni rezultati.

Abstract (english)

Energy efficiency and environmental friendliness of the ship have become important parameters in the ship design process. Also, the International Maritime Organization is paying increasing attention to reducing the carbon footprint of maritime transport. From this aspect, special emphasis is placed on the study of ships that sail in coastal navigation, i.e. populated areas and have the best perspective to reduce the carbon footprint taking into account their operational regimes. A large number of fishing vessels also sail in coastal navigation. Therefore, the goal of this paper is a conceptual solution for the electrification of purse seiner with the purpose of increasing the energy efficiency of the ship, but also to reduce the carbon footprint. Electrification of fishing vessels is in its early stage, since in recent years electrified fishing vessels just started to be built. Analyzing the fuel consumption of a similar purse seiner and the typical operational regimes of the selected purse seiner, it was determined that there are prerequisites for the installation of a hybrid energy system that would increase the ship's energy efficiency and reduce the carbon footprint. Furthermore, the thesis offers a conceptual solution of a hybrid energy system with diesel generators and batteries and an electric motor that drives the propeller. The energy balance of the conceptual hybrid solution and operating regimes are presented. At the end, an analysis of lifetime costs was performed for the existing energy plant of the purse seiner and for the hybrid one, and the obtained results were compared.
