Abstract

U ovom završnom radu analizirane su tehničke značajke ribarskih brodova i njihova povezanost s dekarbonizacijom ribarskih operacija, s naglaskom na koćare i plivaričare. Praćenje energetskog profila ribarskih plovila na koherentan način može otkriti izvore neučinkovitosti i omogućiti primjenu pouzdanih i ekonomski isplativih intervencija za rješavanje tih problema. Ribarski alati koriste energiju intenzivno, što može dovesti do povećanja potrošnje goriva i narušavanja ekonomske održivosti ribarske industrije. Ugljični otisak analiziran je kod ribarskih brodova, s naglaskom na brodske energetske sustave i potrošnju goriva, kao i faktore koji utječu na emisije stakleničkih plinova. Kao zaključak završnog rada, utvrđeno je da ribarska industrija ima veliki potencijal za dekarbonizaciju ribolovnih operacija kroz primjenu održivih materijala, smanjenje otpada i korištenje obnovljivih izvora energije. Također, utvrđeno je da je porast ugljičnog otiska veći kod plivaričara u usporedbi s koćarima, što ukazuje na potrebu za daljnjim istraživanjem i razvojem inovativnih tehnologija koje će doprinijeti dekarbonizaciji ribolovnih operacija i održivom razvoju ribarske industrije.

Abstract (english)

This thesis analyzed technical characteristics of fishing vessels and their relation to decarbonizing fishing operations, with a focus on trawlers and purse seiners. Coherent monitoring of the energy profile of fishing vessels through an energy audit can identify sources of inefficiency and allow for the implementation of reliable and cost-effective interventions to address these issues. Fishing equipment uses energy intensively, which can lead to increased fuel consumption and compromise the economic pillar of sustainability of the fishing industry. The carbon footprint was analyzed for fishing vessels, with a focus on ship energy systems and fuel consumption, as well as factors that influence greenhouse gas emissions. As a conclusion of the thesis, it was determined that the fishing industry has great potential for decarbonizing fishing operations using sustainable materials, waste reduction, and renewable energy sources. Additionally, it was found that the increase in carbon footprint is greater in purse seiners compared to trawlers, which indicates the need for further research and development of innovative technologies that will contribute to the decarbonization of fishing operations and the sustainable development of the fishing industry.
