Abstract: In this article, a systematic solution for mitigating the DFG (Derelict Fishing Gear) problem has been presented using an example of a DFG wreck operation. The planning process has been described in detail and the influence of ghost net recovery on the marine environment has been shown. The research was performed on selected wrecks found in the Polish economic zone and the method consisted of scanning the sea bottom using 2D sonar. Based on the information obtained by the sonar, the ghost nets were later retrieved using a creeper (in cases where the ghost nets were lying on the sea bottom) or with the help of divers (in cases where the nets were sitting on the wrecks). The results have shown that, taking into consideration the research area of the Baltic Sea, the presented method will be satisfactory in most case

Title: Concept of LNG transfer and bunkering model of vessels at South Baltic Sea Arena

Author/Authors: Maciej Gucma, Andrzej Bąk, Ewelina Chłopińska

Place of publication: Annual of Navigation

Year: 2018

Keywords: LNG, bunkering of gas, supply chain

Abstract: At first part of the article methods of SOx (sulphur oxides) emission reduction is presented along with the description of LNG (Liquefied Natural Gas) as a bunker fuel for vessel. As-sumptions for the methods of bunkering between different LNG driven vessel and bunker means is presented. Last part presents assumptions for optimization method and detailed fac-tors to be used in the further work. Optimization of Location-Route Planning (LRP) model with dynamics is presented as starting idea for next steps

Title: The Modernization of the Mrzezyno Seaport. Applaying Simulation Studies to Define the Variants of the Expansion of the Entrance Breakwater

Author/Authors: Renata Boć, Lucjan Gucma, Andrzej Bąk

Place of publication: Annual of Navigation

Year: 2017

Keywords: model of manoeuvring a ship, navigation, safety, designing seaports, breakwater optimization

Abstract: Objective reasons, such as climatic changes, larger vessels, sometimes the impracticality of the current solutions, determine the interest of decision-makers in rebuilding the existing ports and breakwaters. Tested simulation models allow for a thorough analysis of the possible modernization variants taking into account the variability of basic parameters. The article presents research results related to the optimization of the Mrzezyno seaport with respect to navigation safety and the possibility of larger vessels calling at the port after its modernization. In the paper, real time simulation methods based on manoeuvre simulators were applied. Two different variants that can be implemented from the technical point of view were studied. Following a multidimensional analysis that took into consideration increased comfort of ship manoeuvres in the port and navigation safety, one variant was indicated as the optimum. The aim of the research results is to help design new solutions in the case of the modernization of the Mrzezyno seaport.

Title: Stochastic Model of Ships Traffic Capacity and Congestion - Validation by Real Ships Traffic Data on Świnoujście - Szczecin Waterway

Author/Authors: Lucjan Gucma, Andrzej Bąk,Sylwia Sokołowska

Place of publication: Annual of Navigation

Year: 2017

Keywords: ship traffic stream model, waterway capacity, ship intensity, congestion, ship intensity, ship traffic streams

Abstract: Paper presents validation of previously created stochastic ships traffic stream model by the real data of ships delays on Świnoujście — Szczecin waterway. The model is mostly based on Monte Carlo methodology. The model is microscopic which means that each ship’s model is treated as separate object possessing given attributes. As the main parameter of presented validation total waiting (delay) time of ships have been applied. The time of ships delays was possessed from Szczecin VTS centre and compared with the model output.

Year: 2017

Keywords: Port Manoeuvering, Port of Szczecin, Przemyslowy Canal in Szczecin, Applying Simulation Study, Navigation Safety, Safety of Navigation, Parameters of Waterways, Harbour Approach Channels Design

Abstract: The increasing sizes of ships and lack of functionality of the existing solutions determine the interest in rebuilding the already existing solutions. Simulation models allow to analyse the possible modernisation variants taking into account the variability of elementary parameters. The article presents analysis results for the Przemyslowy Canal in Szczecin with respect to navigation safety and regulating traffic regulations in the Przemyslowy Canal taking into consideration the interests of all subjects involved. The paper applies real‐time simulation methods based on manoeuvring simulators. After a thorough analysis that took into account the safety of navigation, further possibilities of development have been determined. Study results are aimed at designing new solutions in case of modernization of the Przemysłowy Canal in Szczecin.
