  • Pleskacz, Krzysztof (Scientific Journals of the Maritime University of Szczecin, Zeszyty Naukowe Akademii Morskiej w Szczecinie, 2015)
    The author discusses the impact of hydro-meteorological factors on the safety of fishing vessels through the presentation and discussion of the events that have taken place on the Polish fishing ships in the area of the Baltic Sea. Because it is not possible to compare the hydro-meteorological conditions on the ocean with the conditions of the closed sea, what is the Baltic Sea – the author has limited consideration to the South and the South-East Baltic which is the main area operation of Polish fisheries.It focuses mainly on criteria which have a direct impact on the safety of the fleet due to the size and nature of the work of fishermen.

    This article analyzes some maritime accidents involving passenger ships that occurred in the Baltic Sea. Existing forms of passenger transport by sea have been identified, and passenger-ship accident statistics in the years 2003 to 2013 are presented. We discuss threats that may exist in passenger transport such as, technical, operational and navigational risks, as well as threats caused by human error and bad weather. In the last part of the paper, we analyze the cause and effect of selected incidents of passenger ships in the Baltic Sea, which include the grounding of the ship MS Amorella, the Stena Spirit ferry collision with infrastructure, and the collision of two ships, the MS Gotland with HSC Gotlandia II. The impact of the human factor on the safety of passenger ships is also analyzed.

    This paper presents an overview of ship traffic volume and accidents in the Baltic Sea with a special focus on the Gulf of Finland. The most common accidents are groundings and collisions, usually reported to be caused by human error. The annual number of Baltic Sea accidents reported to HELCOM varied from 34–54 for collisions and 30–60 for groundings. The number of yearly port calls varied from 468–505 thousand with a peak in 2008. Exact port call data could not be found for all ports and hence had to be estimated. The number of line crossingings in HELCOM AIS data was found to be a good, rough surrogate measure for the total number of port calls and could be used if more precise port call data was not available. By analyzing two separate accident databases, an estimate for accident underreporting was calculated. Different statistical methods yielded an underreporting rate in the range of 40–50%. Lastly, the true number of accidents was estimated, based on the estimated underreporting percentage for the Baltic Sea. Based on these results, the true number of true accidents should be first estimated if accident statistics are used in building or validating maritime risk models. When using such models or accidents statistics in decision-making, the underlying uncertainty in the accident statistics should be taken into account as the underreporting frequency estimates are only approximations of the real number of accidents.
  • Monieta, Jan (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    This article presents selected results of investigations on adverse events of ships throughout one year. The in- vestigations included mainly merchant vessels used to transport bulk material and heavy objects. Ships have been divided into functional systems and elements and into navigational and machine parts. An attempt was made to classify the causes of accidents and evaluate material losses. The quantitative analysis of the causes of the events leads to different conclusions than those reached on the basis of the analyses of losses. Although the failures on-board the vessel occurred more frequently, the costs of machine adverse events were larger. The most critical consequences was fire of a ship caused by loosening of the bleed screw of the fuel filter. Auxiliary engines of the vessel were operated in different external and internal conditions, and were fed by distillation fuel. As a consequence, the evacuation of the crew and fire suppression were required, using the CO 2 installation of the ship. The ship was stopped and deprived of its primary sources of electric energy. An analysis of the event was along with the elaboration of a plan of preventive measures. The results should be useful for selecting the monitored diagnostic objects of vessels.

    Navigational safety of inland vessels in the Międzyodrze and Szczeciński Węzeł Wodny area
  • Orymowska, Joanna; Sobkowicz, Paulina (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The most important aspect of the transport of goods by water, including inland waterways, is navigational safety. Formal Safety Assessments (FSAs) are widely-adopted methods of risk analysis used to assess safety. By defining potential risks and describing event scenarios, FSAs allow the estimation and minimization of the level of risk of individual events. The current article presents the characteristics of accidents on inland waterways and the classification of accidents, with a discussion of their effects. After analysis, the research area was narrowly defined to vessels passing under bridges, and the threats arising from barges descending from the axis of the fairway. On the basis of the analysis, the authors have offered a risk assessment model of inland vessel collision with some element of navigational infrastructure during under-bridge passage. Event Tree Analysis (ETA) was used to carry out hazard identification.
