The aim of this paper is to identify what attitudes towards safety performance indicators influence the attitudes towards successfulness of ISM Code implementation among contemporary seafarers. Secondly, the goal of the research was to obtain insight into the seafarer’s attitudes towards the current state of ISM implementation and safety performance. Consequently, a sample of N=330 seafarers was examined regarding their attitudes towards safety performance variables and ISM Code implementation. By using multiple regression analysis it was concluded that well designed and structured safety rules and procedures, positive work environment and adequate communication can make significant contributions to seafarers’ attitudes towards ISM implementation.

The paper estimates the exhaust emissions of marine traffic in the Port of Rijeka based on the ship’s data obtained from the pilot company. The Port of Rijeka is the largest port in Croatia that includes several berthing locations with different terminals. The estimation is made for each of them respecting carbon dioxide (CO2), nitrogen oxides (NOx), sulphur oxides (SOx) and particulate matter (PM) as well as for the amount of total emissions for the area. The aim is to prepare basic records for estimation and further monitoring with respect to changes in the ongoing environmental regulation and restrictions. This paper will contribute to the overall national strategy of preparing shipping emission inventories for the Republic of Croatia. The estimation method is based on the bottom–up approach widely used in such research that starts with ship characteristics and activities when approaching the port.

The paper presents and processes data on inspections of the individual Memoranda (regions) and compares the overall number of ship detention cases. Also, the paper identifies the differences in various regions in the same period as well as their causes and consequences. Container traffic plays a key role in the international trade. Therefore, the research is based on a comparison of the inspection statistics (in general) and the ship detentions share with the total number of inspections and detentions of the container vessels for each region and the same period. The data have been collected from the annual reports of the individual Memoranda (regions), covering a five-year period, from 2015 to 2019. The results of the research have pointed to partially successful attempts to harmonize and standardize the inspection procedures, as well as to the problem of the non-existent uniformed inspection system.

The paper estimates the exhaust emissions of marine traffic in the port of Šibenik. The results of the analysis were obtained by including the following gaseous pollutants: nitrogen oxide (NOX), sulphur oxide (SOX), particulate matter (PM), volatile organic compounds (VOCs) and carbon dioxide (CO2) as greenhouse gas. In order to gain results and estimate the emission of harmful gases in the port of Šibenik, the passenger and the cargo throughput were taken into account. The activities of the ship during which the exhaust gases are emitted into the atmosphere are slow cruising in the reduced speed zone, manoeuvring and hotelling. The “bottom-up” method used in the emission estimation takes into account the ship’s engine power, engine load factor, fuel type, the emission factor, time of cruising and time hotelling in the port of Šibenik. The results of the analysis have shown that approximately 70 % of total emissions come from passenger ships (cruise ships) and 30 % from cargo ships.
