Autor/Autorzy: Dorota Jarząbek, Kinga Drwięga

Miejsce publikacji: European Research Studies Journal, Issue 5 2021

Rok: 2021

Słowa kluczowe: Simulator Pisces II, sea temperature, crude oil, viscosity, oil spill

Abstrakt: The purpose of this study was to analyze influence of sea temperature on oil spill at constant air temperature. The possibility of using computer simulation to predict the behavior of oil spills at sea enables both to make better use of the forces and resources at their disposal to control them. Therefore, an attempt was made to analyze effect of selected simulation parameters (related to hydro meteorological conditions) on the response of the oil spill depending on the type of spill (type of oil spilled) under the same simulated weather conditions.

Tytuł: Ecological aspect of vessel decommissioning market

Autor/Autorzy: Dorota Jarząbek, Kinga Drwięga

Miejsce publikacji: European Research Studies Journal

Rok: 2021

Słowa kluczowe: ecology, recycling, scrap yards, decommission market, South Asian shipyards

Abstrakt: The article shows the needs of vessel decommissioning market. Collected data used in the paper consist period of 2014-2019, before the COVID- 19 epidemy starts. To improve health, safety and life of workers as well
as environmental protection related to the decommissioning process, which mainly take place in the South Asian shipyards, the concept of Design for Recycling DfR and Hong Kong Convention are brought up into the daylight. Implementing the DfR is to make the whole decommissioning process as simple and cost-effective as possible. The vessel design stage, with selection of building materials and new technologies used, is the area where constant changes and updates are taking place. Making the Honk Kong Convention alive, will put the duty on the ship owners to
dismantle their vessels in shipyards, which are authorized by the adequate Administration of State. Methodology/Approach: Data used for analysis were implemented from UNCTAD. Final deductions has been shown
in tables and figures. Findings: Ratification of HK Convention is essential to improve protection of the workers involved in
decommissioning process and to protect environment. Practical Implications: Analysis presented in the article underline the need of changes in vessel dismantling market. Originality/Value: Collected data are the basement into the future analyses of the whole decommissioning market area.

Tytuł: Statistical analysis of parameters of selected worldwide yacht ports and marinas in terms of design guidelines

Autor/Autorzy: Lucjan Gucma, Kinga Drwięga, Radosław Butrymowicz

Miejsce publikacji: Annual of Navigation

Rok: 2018

Słowa kluczowe: statistical analysis, design guidelines, port parameters, yacht port, marina, turning basin area.

Abstrakt: In relation tothe current development of the sailing modernization and development of yacht ports and marinas are necessary.The preparations process, stages of the design, anal-yses and finally construction of yacht ports is time-consuming and laborious. In the article a statistical analysis of selected design parameters was described. In order to carry out the analysis a database was created based on 210 ports from different regions of the world such as: Europe, North America, Australia and South Asia. Google Earth was used to obtain the actual values of the analyzed parameters. Most of achieved results was described in the form of tables or graphs.

Tytuł: Method for reserve determination of static and dynamic list of bulk carriers applied to the dynamic under keel clearance system in the Port of Świnoujście

Autor/Autorzy: Kinga Drwiega, Lucjan Gucma, Rafał Gralak

Miejsce publikacji: Annual of Navigation

Rok: 2017

Słowa kluczowe: bulk carrier, dynamic UKC, simulation methods, analytical methods, heel,pressure transmitters

Abstrakt: The paper presents the methodology for determining the components which are related to heel of bulk carrier with one component excluded —the heel of vessel due to waves. The described method was applied to the
system, which is dedicated to use in determination of UKC of vessels at the approach to the Port of Swinoujscie. The method includes deter-mination of heel caused by: draught reading errors, wind,current, tugboats and heel related to vessel maneuvers. To determine heel related to vesselmaneuver 2-stage methodwas car-ried out. The first stage
simulation was used to identify the parameters of shipmove-ment. At the second stage, the maximum heel of Bulk Carrier were calculated by using analytical methods. Presented method was implemented to the item rating under keel clearanceat the approach to the Port of Swinoujscie

Rok: 2017

Słowa kluczowe: port manoeuvering, under keel clearance (UKC), Port of Swinoujscie, Response Amplitude Operator (RAO), UKC Reduction, graphical user interface, Liquefied Natural Gas (LNG), LNG Vessels

Abstrakt: The article presents a system for determining dynamic under keel clearance. In order to build a DRWPS system, a mixed model was created based on the analysis of math models. The system includes advisory
software for defining the conditions for the entering of large LNG vessels in the context of under keel clearance and software was built to support the decision-making of operators who are responsible for introducing these vessels to the Port of Swinoujscie.

Słowa kluczowe: analytical methods, dynamic UKC, LNG carrier, pressure transmitters, simulation methods

Abstrakt: This paper presents a methodology for determining the components related to the heel of liquefied natural gas (LNG) carriers, excluding the heel of the vessel due to waves. The described method was applied to the description of under keel clearance of vessels approaching the outer port of Świnoujście. The method includes the determination of heel components caused by: draught reading errors, wind, current, tugboats and vessel maneuvers. Determination of the last component was carried out using a 2-stage method. In the first stage, simulation methods were used to identify the parameters of ship movement. In the second stage, the maximum heel of LNG carriers was calculated by analytical methods.
