Abstract (Croatian)

Suvremena rješenja u razvoju brodskih energetskih sustava (BES) zasnivaju se sve češće na integriranim energetskim sustavima (IES), čija je glavna značajka centralizirana proizvodnja ukupno potrebne količine električne energije korištenjem raznovrsnih pogonskih strojeva i uređaja, primjena elektromotornih propulzijskih sustava i visoki stupanj utilizacije otpadne toplinske energije. Sadašnje normativne metode za ocjenu energetske učinkovitosti i ekološke prihvatljivosti BES-a temelje se na Projektnom indeksu energetske učinkovitosti (eng. Energy Efficiency Design Index – EEDI) koji je definiran kao relativni omjer između ekvivalentne emisije CO2 i pripadajućeg gospodarskoga učina broda. Iskustvo u primjeni EEDI-a pokazuje da nije primjenjiv za IES-e. U sklopu ovoga doktorata analizirana je povezanost različitih parametara koji utječu na energetske i ekološke značajke različitih konfiguracija IES-a. Na temelju te analize definirana je metodologija pomoću koje se u brodograđevnoj praksi može valorizirati indeks energetske učinkovitosti i ekološke prihvatljivosti (eng. Index of Energy Efficiency and Environmental Eligibility – I4E) različitih konfiguracija BES-a (uključujući IES-e). Primjenom I4E na flotu ro-ro putničkih brodova pokazano je da je integralni utjecaj brodova s IES-ima na okoliš manji od brodova s konvencionalnim BES-ima.

Abstract

Modern approach to the marine power system design is more often based on integrated power systems. These systems are characterized by the centralized production of the electrical energy from different prime movers, application of the electrical propulsion system and a high utilization factor. Current regulations introduced Energy Efficiency Design Index (EEDI) as a technical measure to increase ships efficiency. The methodology of EEDI calculation is based on the relative CO2 emission from ship power system and on the benefit for the society. This methodology is not applicable for integrated power systems (IPS). Hence, the analysis of different parameters influencing ship energy efficiency and overall environmental impact is performed. A new model is defined that can be widely used to evaluate the ships energy efficiency and environmental impact through the Index of Energy Efficiency and Environmental Eligibility (I4E). By calculating the I4E for a fleet of ro-ro passenger ships it has been observed that ships with IPS have lower overall environmental impact than ships with conventional power systems.
