Abstract

Pomorski prijevoz je najučinkovitiji i najjeftiniji način transporta robe, a većina svjetske
trgovine se odvija morem. Međutim, iz međunarodnog pomorskog prometa ispušta se značajna
količina štetnih plinova. Danas se u pomorskom prometu još uvijek većinom koriste goriva
fosilnog podrijetla, kao što je dizelsko gorivo, čije izgaranje uzrokuje visoke emisije štetnih
plinova. Upotreba goriva fosilnog podrijetla, zbog štetnog učinka na okoliš mora biti smanjena.
Međunarodna pomorska organizacija nastoji smanjiti emisije štetnih plinova u pomorskom
prometu putem regulativa, a primjećuje se tendencija sve strožeg regulatornog okvira koji
ograničava takve emisije. U težnji za zamjenom klasičnih goriva fosilnog podrijetla, javljaju se
alternativne opcije koje emitiraju znatno manje količine štetnih plinova u okoliš prilikom
proizvodnje goriva te u eksploatacijskim uvjetima. U završnom radu razmatrana su alternativna
goriva za brodske primjene, te je napravljena usporedba s klasičnim gorivima fosilnog
podrijetla. Isto tako, dan je pregled konfiguracija brodskih energetskih sustava pogonjenih
isključivo alternativnim gorivima ili „dual fuel“ konfiguracijom pogona. Ekonomska analiza
provedena je na trajektu Kornati te kontejnerskom brodu One Mackinac, kao primjerima
brodova za priobalnu i prekooceansku plovidbu.

Abstract (english)

Maritime transport is the most efficient and the cheapest way of transporting goods, resulting
in most of world trade being based on sea transport. However, international shipping is a
significant source of harmful gas emissions. Today, maritime transport still mainly uses fuels
of fossil origin such as diesel fuel, the combustion of which causes high emissions of harmful
gases. The use of fossil fuels must be reduced due to their harmful effect on the environment.
International Maritime Organisation (IMO) strives to reduce the emission of harmful gases in
the maritime transport by its regulations and there is a trend towards more strict regulatory
framework that limits harmful emissions. In tendency to replace traditional fossil fuels,
alternative fuel options that emit significantly smaller amounts of harmful gases into the
environment during production and under exploitation conditions are emerging. Within this
thesis, alternative fuel options for marine applications were considered and a comparison with
traditional fossil fuel is given, as well as an overview of configurations of ship energy systems
powered exclusively by alternative fuels or "dual fuel" drive configuration. The economic
analysis was carried out on the ferry Kornati and the container ship One Mackinac, as
illustrative examples of short-sea and long-distance vessels.
