    Opis:
    Appendix III of MARPOL´s Annex VI sets out the criteria and procedures for designating an emission control area (ECA).These criteria includes: a clear delineation of the proposed ECA; types of emissions proposed for control, land and sea areas at risk; emission quantification and impact assessment; prevailing weather conditions; data and quality on marine traffic; land based measures concurrent with the ECA adoption and the relative costs of reducing emissions from ships. This paper analyses the climate parameter together with traffic conditions: prevailing weather conditions as a parameter to be kept in mind for the adoption of a future ECA in the Mediterranean Sea. Preliminary results would show how marine emissions coming from existing traffic will impact the sea and land ecology in the Mediterranean area.

    Opis:
    The economical development of the world is based on transportation system. More than half of the products transported all over the world are carried by sea. Sea transportation is made with different kind of ships, as bulk carriers, cargo vessels, container ships, tankers. Ships are managed by people. In group or as individual, anybody can make errors. In maritime area these errors have as results accidents and disasters. Many of these events affect especially the environment. As 80% of necessary petroleum products are transported by sea, the risk of a major environment disaster caused by human errors is high. Anyway, over 99% of petroleum cargo transported by sea is carried without incidents. This paper presents the effects of human errors, mostly cases that involved tankers, which were produced in the navigation and operational processes.

    Opis:
    It is studied the distribution of Hg in bottom sediments of estuaries on the banks of the open water area of the Vistula Lagoon and in the Kaliningrad Sea Canal (KSC) isolated from it. Methods for the determination of Hg: inversive voltammetry and highly sensitive flameless atomic absorption spectrometry. It has been established: from spring to autumn the activation of storms and surge events in the lagoon, intensification of the water flushing regime of the channels ensure a significant Hg decrease in river mouths, but in dynamically weakened KSC conditions - an increase in Hg (from 0.05 to 0.85 mg / kg). In KSC bays, the safe level of Hg (0.3 mg / kg) for the period 2000-2015 was not exceeded (0.008 to 0.216 mg / kg), which indicates a favorable ecological and epidemiological situation. Hg determinations by low-sensitivity methods can be used only in qualitative assessments of the variability in concentrations of any dangerous toxicant. Finding a reliable amount of Hg in river mouths requires the use of highly sensitive methods of analysis.

    Opis:
    The aim of the TOPVOYS project supported by the MarTERA ERA-Net Cofund program within the European Commission is to advance and implement analyses tools and decision support system for voyage optimisation. Based on marine weather analyses and forecasts combined with near real time satellite-based observations of wind, wave and surface current conditions as well as sea surface temperature fields the best shipping route are examined. The proposed approach aims to identify the optimum balance between minimisation of transit time and fuel consumption as well as reduction of emissions without placing the vessel at risk to damage and or crew injury. As such it is compliant with the International Maritime Organization guidelines [6] for ship routeing to keep the traffic smooth and avoid accidents, notably in the presence of unfavorable marine meteorological conditions. The tool performances will be demonstrated both in post-voyage analyses and real time operations for the North Atlantic Ocean crossings, voyages from Europe through the Mediterranean Sea and the Suez Channel to the Far East (e.g. China, South Korea) and voyages around Southern Africa.

    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:
    Marine abandonment immersion suits are a vital piece of safety equipment intended to protect individuals from exposure to harsh environmental elements. The operational effectiveness of a well maintained and fitted suit depends on the ability of a user to correctly don a suit system. Thirty-two participants performed immersion suit donning trials in six experimental conditions. Dynamic, pre-abandonment marine emergency scenarios were simulated using a six degrees of freedom motion platform and varying environmental lighting levels. This article details user-suit interaction challenges encountered throughout immersion suit donning tasks and examines their connection to safety and survival in marine emergencies. Analysis of user-suit functionality during the donning process is critical for identifying current deficiencies in order to develop future design solutions, training methodologies and ultimately improve users’ practical competencies.

    Opis:
    It is essential to evaluate safety of marine traffic for the improvement of efficiency and safety of marine traffic. Spread of AIS makes observation of actual marine traffic more easily and faster than before. Besides, description of collision avoidance behaviours of ships are indispensable to simulate a realistic marine traffic. It is important to develop and implement an algorithm of collision avoidance corresponding to a target traffic or target area into the marine traffic simulation because actual actions for collision avoidance depend on circumstances where ships are sailing. The authors developed an automated marine traffic simulation system with AIS data. And in this paper, we proposed a series of systematic procedures for marine traffic simulation including analysing for collision avoidance behaviours using AIS data.

    Opis:
    When it comes to gas turbines, their main problem concerning pollutant emissions is represented by nitric oxides. Among other emissions, sulphur oxides being much reduced due to the use of liquid distilled and gas fuels with a low content of sulphur. Using water or steam injection became the favourite method during the '80s and especially the '90s since "dry" methods and catalytic reduction were both at the beginning of the development phase. Catalytic convertors have been used since the '80s and they are still used although the costs of renewing the catalyst are very high. In the last twenty years a gradual decrease has been registered on the limits of nitric oxides from 75 ppm to 25 ppm, and now the target is oriented towards the 9 ppm level. The evolution of burning technologies of combustion makes it possible to control the level of production of nitric oxides even from the source without being necessary to use "humid" methods. This, of course, opened the market for gas turbines because they can function even in areas with limited quality water reserves, such as maritime platforms and in the desert. In this paper, we are going to show that, although water injection is still used, "dry" control technologies of burning became favourite methods for the majority of users on the industrial power generators market. The great dependency between the creation of nitric oxides and the temperature reveals the effect of direct water or steam injection on reducing nitric oxides. Recent research showed that a reduction up to 85% of nitric oxides may be obtained by using the water or steam injection all together with the improvement of aerodynamic character of the burning room.

    Opis:
    This paper presents a comparative analysis of manoeuvring patterns through the fairway which is marked with physical and virtual Aids to Navigation (AtoN). The impact of V-AtoN environment on decision-making and on consequent manoeuvres has never been studied in such a way. The results published in this paper were obtained using TRANSAS Navi Trainer 5000 and TRANSAS ECDIS 4000 simulators where 12 deck officers with at least 5 years of sea service participated. The results of the study indicate that there is a significant difference in manoeuvring patterns between the two environments. In case of virtual environment, more intense drift angles, ROTs as well as XTDs are observed. The paper demonstrates significant impact of virtual environment on behaviour of OOW.
