The ship’s power system is one of the most important systems on board. It is designed for uninterrupted power supply to all ship consumers under different conditions of exploitation. When designing a ship, various optimizations are conducted to build the ship as economically and environmentally friendly as possible. The paper aims to analyze the possibility of applying renewable energy sources (RES), particularly solar and wind energy, on an existing vessel by conducting technical and economic analysis. Data for the solar hour’s number and wind distribution are gathered from the six locations in the Adriatic Sea over 32 years period. Firstly, it was investigated if data were position dependent or independent. Performing a Pearson correlation coefficient and an ANOVA analysis with F-test, it was concluded that the RES analysis is position-independent (p > 0.05, p = 0.826). Secondly, the energy system model created in Simulink was used for the analysis of the electrical network fundamental parameters. Finally, the object of the analysis is the total costs of procurement, installation, and maintenance of the system within a period of 25 years. Consequences are savings in the cost of exploitation and reduction of harmful gas emissions. The use of solar energy would result in savings of 111,556 l of diesel fuel, while the savings from wind energy would be 170,274 l of diesel fuel for 25 years.

This paper presents the measurement process of the emissions from marine diesel engines. The emission measurement was carried out by the certified TESTO 350 Maritime exhaust gas analyzer on the Juraj Dalmatinac ferry Caterpillar C32 engines. The gas analyzer records the concentrations of nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and sulfur dioxide (SO2). TESTO 350 emission sampling probe was set at the end of the exhaust pipe. A combustion emission measurement was performed during a Split – Supetar (Brač) trip and backwards with the total duration of 110 min. The emissions are estimated for two trip phases: “maneuvering” and “at sea”.

Radom je na temelju dostupne novije znanstvene literature istražena teoretska osnova koncepta saveza maraka - kobrandinga te je uočen značaj strateškog pristupa tom konceptu, implikacije koje nastaju zbog potrebe njegova integriranja u temeljno poslovanje poduzeća, njegova veza sa mogućnošću ostvarivanja konkurentske prednosti, te zaključno problemi i nedostatci ovakvog saveza. Istraživanjem teorije saveza maraka – kobrandinga, uočeno je da se zbog novih okolnosti na tržištu mnoge tvrtke odlučuju na suradnju i uspostavljaju saveze s drugim tvrtkama kako bi zadržale vlastitu poziciju ili osvojile nova tržišta pa se tako zamjećuje veća zastupljenost kobrandinga u svakodnevnoj poslovnoj praksi. Kobranding postaje jedno od oružja za koje se tvrtke odlučuju u kriznim vremenima kako bi sinergijskim učinkom zadobile konkurentnost u napetoj tržišnoj utakmici, te povećali prepoznatljivost branda kao i percepciju vrijednosti istog u svijesti potrošača.
