    Exhaust Gas
    Opis:
    Exhaust gas emissions from ships are increasingly polluting the air environment seriously. Therefore, the MARPOL 73/78 Annex VI is applied for all ships from 2017, Annex VI provided that the concentrations of NOx,SOx CO contained in ship’s exhaust gases must be less than 6.4 g/kWh, 0.6 g/kWh, and 5.5g/kWh respectively. Today, there are many solutions to reduce pollution emissions from exhaust gas of ships, such as improving combustion, using oil emulsion, using biofuel,…However, these solutions also have a handful of disadventages such as being unable to thoroughly resoulve problems, high cost, and very difficult to improve the quality of ship exhaust gas emissions for old ships. Exhaust gas treatment method uses a centralized treatment system where exhaust gas from the thermal engines is taken in a centralized treatment system before discharging into the air. After centralized treatment system, in comparision with raw exhaust gas, soot can be reduced by 98%, NOx can be reduced by 75%, SOx can be reduced by 80%. This method of treatment is not only low cost, good quality but also make marine heat-engines still use traditional fuels as well as need not improve its structure.

    Opis:
    Cruising tourism is becoming increasingly popular, the number of cruises having seen a continuous increase since the 1970s. In Croatia as well there is an upward trend in the number of cruise passengers and ports. Of all Croatian ports, it is the port of Dubrovnik that has had the most calls by foreign cruisers. The paper analyses the available statistical data on the maritime cruise market in Europe with special reference to the Mediterranean countries. In the national context, a presentation of cruise traffic in the port of Dubrovnik is given. Although this type of tourism contributes to the development and improvement of the economy, it also has a negative impact on the environment through air pollution by CO2 emissions, subsequently affecting human health as well. The authors investigate the level of CO2 emissions in the area of the port of Dubrovnik. CO2 emissions were calculated based on cruiser activity, the calculations being based on CO2 emissions for three ship navigation modes - slow steaming on arrival and departure, manoeuvring on arrival and departure, and for a berthed ship. The aim of the research was to provide a better insight in the emission inventories in this area. This research can also be applied to other port areas.

    Opis:
    The year 2022 was marked by economic risks with potentially very sensitive impacts for countries in the Black Sea region. Given the limited capacity of Ukrainian ports, as well as the sanctions imposed on Russia, due to ongoing conflict, it was necessary to identify new destinations capable of taking over the flow of goods that normally went to the countries involved in this conflict. In addition to the risks specific to maritime transport, the risk of armed conflict comes with new challenges that can also materialize in the form of environmental impact. To analyze this potential impact, the study is being focused mainly on the analysis of the pollution risk generated by the emissions caused by the vessels calling the container terminal CSCT, located in Constanța harbor, and the emissions generated by the vehicles moving in the terminal. As estimated from the start all levels of pollution have increased, with the level of CO2 increasing from 11072.7 tons in 2021 to 11915.7 tons in 2022. The NOx emissions have a similar trend, as well as the other emission level measured and calculated.

    Opis:
    Should an oil spill of tier III magnitude occur in the Northern Adriatic, there is a high probability that the oil will reach and pollute the surrounding coastline. Therefore, it is vital to conduct coastal vulnerability studies to develop priority plans and coastal vulnerability maps to help first responders protect the coastline. As there is no common contingency plan for oil spills in the Northern Adriatic, three countries, Italy, Slovenia, and Croatia, which share the area, decided to participate in the North Adriatic Incident Response System (NAMIRS) project. Part of the project was to conduct a coastal vulnerability study in the area. One of the three pillars for determining vulnerability, in addition to the ecological and geomorphological factors, is the socioeconomic aspect, which was studied as part of the research. As there are no clear scientific methods to determine the vulnerability of the socio‐economic factors, a survey was conducted where the participants gave their subjective opinion on its value. This was done through three workshops organised in each participating country, where professional stakeholders familiar with the state of socio‐economic activities assessed their vulnerability. The values obtained were combined with the assessments of the geomorphological and environmental factors and gathered in a coastal vulnerability layer, which was incorporated into a GIS as a standard coastal vulnerability map that will help first responders prioritise coastal protection. The research results will also be useful globally and not just in the area studied by NAMIRS, since the method used is readily applicable to any part of the world.

    Opis:
    Ships have an important role in among the factors causing marine pollution. Marine pollution by ships damages sea life, which effects human health indirectly, in addition it restricts usage of sea for different purposes. Increasing comprehensive and compelling liabilities related with environmental components and subjects day by day are expected results for environmental science and engineering applications according to 60% of our responsibilities of European Union Integration development. In today’s’ world, where global warming is an issue of high priority and makes us feel its impacts in our lives, leaving a livable world to the next generations is now a primary goal for all. Determination of marine pollution caused by ship operations issue is a multiple criteria decision-making (MCDM) problem, and requires MCDM methods to solve it. Therefore, the role of ship factor in maritime pollution and the possible reasons of this argument can be quantitatively evaluated based on expert knowledge and MCDM methodology. To investigate what makes to reduce the first “caused by ship operations " in marine pollution, the decision-making trial and evaluation laboratory (DEMATEL) method approach was applied in this study.
