Słowa kluczowe: Ishikawa diagram, marine accidents, navigation, safety, sustainability, social systems, situational systems

Abstrakt: As in any industry exposed to risk, human and organizational factors are the main stakes of maritime safety. Understanding the causes and risks of maritime accidents is integral to the sustainability of shipping. The investigation of marine accidents is a crucial tool for their identification in areas related to operations and ships, including social and situational systems, their design, and technical systems. The authors conducted a cause–effect analysis of marine incidents. For this purpose, case-by-case analysis and an Ishikawa diagram were used, which is a tool that helps identify actual or potential causes of accidents. The study showed that by far the most significant cross-section of causes of accidents were elements of social and situational systems that affect the safety of the ship, crew, and environment. The least significant contribution came from the machinery area. Through the detailed descriptions, a picture emerges not so much of a lack of knowledge of the regulations as of a failure to comply with existing procedures or best practices. In the authors’ opinion, more emphasis is needed on preventive measures, including safety culture, training, competence assessment, and increased awareness of the need for sustainability.

Tytuł: Time Shift of Wind Influence on the Movement of Surface Water Masses in the Szczecin Lagoon

Autor/Autorzy: Lech Kasyk, Krzysztof Pleskacz, Tomasz Kapuściński

Miejsce publikacji: European Research Studies Journal

Rok: 2022

Słowa kluczowe: SAR, wind parameters modelling, wind parameters and forecasting, shipwreck drift modeling, directional correlation

Abstrakt:  The study's specific objectives were to analyze the interaction between the prevailing hydrometeorological conditions and the trajectory of water layer movement in the Szczecin Lagoon (southern Baltic, Poland). Design/Methodology/Approach: Research experiments verifying the drift movement trajectory under various hydrometeorological conditions were carried out in the Szczecin Lagoon. In the presented analysis, 17 fragments from ten drift trajectories were selected, in which there was a clear time shift in the influence of the wind direction on the change of the drifting direction. Statistical analysis of directional and linear data allowed us to link the directions and speeds of drifters moving with the wind parameters recorded in two places, Świnoujście and Trzebież, with an appropriate time shift. Findings: As a result of the research, it was found that the change of the wind direction influences the direction change of the flow of surface waters in the Szczecinski Lagoon with an unavoidable delay. A significant correlation was found between the speed of changes in the wind direction and the initial wind direction. A relationship was also shown between the distance of the test site from the weather station and the registered wind direction change. Originality/value: The presented relationships between some fundamental processes in the energy transfer between wind and water surface may be beneficial for the maritime administration, which is responsible for the safety of navigation in the studied water area. The analysis results can be used in SAR actions and to project the track of water pollutants.

Słowa kluczowe: Safety, surface flow, wind, surface drifter, Szczecin Lagoon.

Abstrakt: Purpose: The article presents a comparative analysis of the drift movement in the water area of Szczecin Lagoon (southern Baltic, Poland) and wind parameters in the examined region for the dry summer season. Design/Methodology/Approach: Experimental tests were conducted to determine the relationship between the drifter movement parameters and wind parameters in Szczecin Lagoon area. A set of surface drifters was designed for the experimental study at the Maritime University of Szczecin. Drifters were custom-made to track surface currents. In situ experiments were performed from the end of June till mid-October 2018. Statistical analysis of directional and linear data allowed to link the directions and speeds of moving drifters with wind parameters recorded in two places, Świnoujscie and Trzebież. Findings: As a result of the conducted research, it was ascertained that the direction and speed of air masses flow are parameters that strongly affect the movement of surface waters of Szczecin Lagoon. A significant correlation was found between the wind direction and the drift direction. The coefficient of surface drift was also specified to determine the relationship between drift speed and wind speed. Originality/value: The presented research is a complete novelty in the area of the Szczecin Lagoon. The results obtained in the study may be beneficial for the maritime administration, which is responsible for the safety of navigation in the studied water area. The analysis can be used for projecting the track of pollutants in water.

Tytuł: Research into leeways in the regions of the Świnoujście– Szczecin fairway on the Szczecin Lagoon

Autor/ Autorzy: Monika Kijewska, Lech Kasyk, Krzysztof Pleskacz

Miejsce publikacji: Scientific Journals of the Maritime University of Szczecin-Zeszyty Naukowe Akademii Morskiej w Szczecinie

Rok: 2019

Słowa kluczowe: leeway, wind, downwind, crosswind, in-situ experiments, surface drifters, fairway, Szczecin Lagoon

Abstrakt: The paper analyzes the influence of air mass movement on moving (the leeway) surface water in the Świnoujście– Szczecin fairway region on the Szczecin Lagoon. The Szczecin Lagoon includes waters of the Odra River estuary (Poland’s second largest river) and the southern Baltic Sea. To calculate the leeway parameters, a relevant surface drifter was outlined and constructed. The data on the leeway of the drifter was obtained from in-situ experiments conducted on the Szczecin Lagoon in the summer of 2018. In turn, the air mass movement data was recorded at meteorological stations in Trzebież and Świnoujście. A statistical analysis of the leeway parameters of the drifter was also presented. Distributions of the leeway and wind speeds in the Świnoujście– Szczecin fairway regions were established. Moreover, linear regressions between the leeway and wind parameters were performed by decomposing the leeway into its downwind and crosswind components for each 10-minute sample. It is worth highlighting that relationships between these components of the leeway and wind parameters were studied for weak, medium, and stronger winds. This research may be useful for increasing navigation safety in the Świnoujście–Szczecin fairway regions on the Szczecin Lagoon.

Słowa kluczowe: Szczecin Lagoon, Surface Current, Wind Parameters, Hydrodynamic Model, Weather Forecast, Numerical Models, Geographic Information System (GIS), High Frequency Surface Wave Radar (HFSWR)

Abstrakt: This study focuses on the investigation of available surface currents and wind parameters for employing them in order to predict the survivor movement in the Szczecin Lagoon waters. For this purpose, the surface currents and wind parameters were generated by selected numerical models and the wind parameters were also measured with the telemetry devices. In this paper, the PM3D hydrodynamic model and the NEMS, ECMWF, GFS weather forecast models have been investigated. The measurements of the wind parameters, recorded at the Brama Torowa I and Trzebież stations, were also analyzed. As part of the research, an expert method was used to evaluate the surface currents parameters. In turn, the method based on comparing the forecasted wind parameters with the measured wind parameters was applied in order to assess uncertainties of these parameters. The comparative analyses of the data on the surface currents and wind parameters have been done and probabilistic models for uncertainties of these forecasted parameters have been formulated. Additionally, relations between the surface currents speeds and the wind speeds, in the case when their directions were consistent, have been also discovered.

Tytuł: The Ultimate Solution of the Deviation Problem for Magnetic Compasses

Autor/Autorzy: Evgenij Łusznikow, Krzysztof Pleskacz

Miejsce publikacji: Zeszyty Naukowe Akademii Morskiej w Szczecinie

Rok: 2018

Słowa kluczowe: magnetic compasses, magnetism, compass compensation, deviation of magnetic compass, safety

of navigation, navigation area

Abstrakt: This article has looked into the role of the magnetic compass in providing navigational safety for ships. The existing requirements of the magnetic compass for safe navigation in case the gyro compass breaks-down and in case of terrorists abusing GPS signals do not solve the problems that occur in everyday life. Therefore, a new rational requirement has been proposed for the accuracy and frequency of deviation adjustment work assuring the safety and cost effectiveness of navigation. Vessel owners and masters have responsibilities to ensure that magnetic compasses are maintained in good working order, are adjusted and accompanied by a table or curve of residual deviations. This article has outlined the most urgent problems for the adjustment of magnetic compasses that apply to all ships irrespective of size and navigation area. The proposed method has been verified experimentally.
