Abstrakt publikacji: One of the components necessary to determine the width of a safe maneuvering area on two-way fairways is a safe passing distance. Existing methods do not consider modern model studies of interactions between passing vessels, additionally, they ignore the influence of the vessel’s position accuracy and navigators’ qualifications. This paper presents a method to determine the passing distance, which is free of the drawbacks of the methods used so far. The proposed method is based on simulation research carried out using an FMBS-type (Full Mission Bridge) simulator. The tests were carried out for three loaded vessels (bulk carrier, tanker, and sea ferry), on four sections of the fairway with different parameters and aids-to-navigation available. The results obtained allowed the modification of the authors’ previous, but still widely used, deterministic–probabilistic MTE (Marine Traffic Engineering) method for determining the width of a safe maneuvering area.

Abstrakt publikacji: There are a number of empirical methods for determining the width of safe maneuvering areas for ships on waterways. These methods are relatively accurate for straight sections of waterways and less accurate for curves of the waterways. When designing waterways in detail or determining the conditions for their safe operation, more accurate methods (e.g., simulations) are used. However, such studies require relatively large expenditure involving the construction of simulation models of various vessels and water areas, and conducting a real-time simulation experiment with a sufficiently large number of maneuvers performed by highly qualified navigators (pilots, captains). This study deals with the problem of determining the width of safe maneuvering areas of ships on the bends of the waterway based on the results of simulation studies. A new empirical method was developed to determine the width of safe maneuvering areas of loaded bulk carriers passing through fairway bends under deteriorated hydro-meteorological conditions. The method was developed on the basis of a generalization of the results of many simulation experiments carried out at various stages of the Świnoujście–Szczecin fairway reconstruction and a determination of the safe operating conditions for ships passing through the fairway.

Słowa kluczowe: offshore wind farm, offshore wind turbine, offshore wind turbine installation terminal, wind turbine installation vessel, wind turbine transport vessel, dimensioning of waterways
Abstrakt publikacji: This article indicates the development trends in the construction of offshore wind turbines worldwide, and the characteristics of existing and planned ships for wind turbine installation and maintenance; it presents an approach to design ports with their future operations in mind. Problem: The safety of navigation in port waterways is the basic restrictions for the construction of harbors (terminals) to handle ships used for the construction of OWT and for increasing their size. Navigational risk is a criterion of navigational safety assessment that allows its accurate estimation in port waterways. Method: The article presents the method for dimensioning port waterways for ships serving offshore sea wind turbine transport and construction. Furthermore, a method for determining the navigational risk of jack-up vessels navigating in port waterway areas is presented. Results: The authors have determined conditions for safe operation of these ships in restricted areas and defined the basic condition of navigational safety. The presented method of navigational risk analysis refers to the departure of a loaded ship carrying offshore wind turbine components in the presently designed port terminal in Świnoujście for handling offshore wind farm projects. Conclusion: These are universal methods that can be applied to the design of ports serving vessels that install offshore wind turbines in various types of waters.

Słowa kluczowe: maritime transport routes; safety of navigation; maritime transport; design of waterways; marine simulation; full-mission ship simulator; maritime traffic engineering; safe maneuvering area; safe operation of the ship; navigational risk
Abstrakt publikacji: Context: From the perspective of marine traffic engineering, a system of port waterways is composed of a set of waterways (port areas), such as approach channels, port entrance, inner fairways (port channels, rivers, lakes), turning basins and port basins of various terminals. The sea waterway must be adjusted to the navigation of specific types of ships, characterized by length, breadth, draft and airdraft. The primary requirement for shipping in sea waterways is the safety of navigation. Each sea waterway has traffic restrictions for the ships using it. These restrictions are called conditions of sea waterway operation or conditions of ship operation in the sea waterway. Problem: There are a number of empirical, deterministic or probabilistic methods to determine the safe width of maneuvering areas on port waterways. The direct application of empirical methods to determine the conditions for the safe operation of ships on the complex waterway, such as the Świnoujście–Szczecin fairway, was impossible due to the complexity of the waterway and various restrictions on its individual parts. Method: The paper presents the assumptions and calculation procedure of a method allowing for the determination of maximum safe parameters of ships in existing complex waterways. Results: The proposed method was used in the preparation of port regulations for the dredged and widened Świnoujście–Szczecin waterway. The results of these calculations are presented as a practical application of the method. Conclusions: This article defines conditions for the safe operation of ships in complex port waterways systems and presents the methodology for determining maximum safe parameters of ships in existing complex port waterways systems.

Słowa kluczowe: maritime traffic engineering; safe maneuvering area; wind turbine installation vessel
Abstrakt publikacji: A paper presents problems related to the safe operation of wind turbine installation vessels in port waterways. It presents a developed method for determining maximum safe lengths of blades of wind turbines loaded transversely on a jack-up vessel leaving a given port. In this method, the safety criterion for navigation is the acceptable risk of accidents, whose scenarios are determined by the identification of hazards in the studied waterway. Based on this safety criterion, the confidence level of the width of the safe maneuvering area of the loaded jack-up vessel and the maximum safe lengths of the transversely loaded wind turbine blades, respectively, are determined.

Miejsce publikacji: European Research Studies Journal
Rok: 2021
Słowa kluczowe: Navigational safety, navigational risks in fairways, ship emergency manoeuvres, ship simulation, maritime traffic engineering
Abstrakt: Purpose: Navigational risk is a criterion for navigational safety assessment on fairways. To estimate navigational risk, we must determine the probability of an accident and its consequences. Design/Methodology/Approach: The authors have developed methods of determining navigational risks caused by deterioration in navigational conditions during the passage of ships through the waterway system and for the estimation of risk caused by shipboard equipment failures. In a simulation experiment, full ships with 5.000 DWT to 100.000 DWT capacity performed emergency stopping after rudder jamming. Findings: The results of simulation tests developed in the form of mathematical models constitute data for the determination of ship’s navigational risk due to rudder failure. Practical implications: The models can be used for defining simplified relationships allowing authors to determine the width of safe emergency manoeuvring areas. Originality value: The procedure has been developed and navigation algorithms for determining the risk associated with the failure of the steering of the vessel passing through the different types of the fairway.

Słowa kluczowe: augmented virtuality; decision support system; safety ofnavigation; marine simulation; MASS
Abstrakt publikacji: The paper presents the results of a study on improving the safety of navigation, during maneuvers in restricted areas, with the use of an augmented virtuality navigation information display. The augmented virtuality solution has been developed by one of the authors and has been described in a previous paper. A set of simulation scenarios has been proposed to study various maneuvers with different types of ships. Models of existing areas and existing ships have been used so the study can be recreated and reevaluated with different types of interfaces. The study is focused on comparing safe maneuvering areas with different information sources used. The results showed that augmented virtuality solution can indeed decrease the safe maneuvering areas and thus increase the safety of navigation for maneuvers in restricted areas.

Tytuł: Areas of emergency maneuvers and the navigational risk of accidents in fairways due to ship technical failures determined by the ship movement simulation method
Autor/Autorzy: Stanisław Gucma, Rafał Gralak, Bartosz Muczyński
Miejsce publikacji: Zeszyty Naukowe Akademii Morskiej w Szczecinie, vol.61(133)2020, pp. 39-47
Rok: 2020
Słowa kluczowe: navigational risk in fairways, consequences of navigational accidents, areas and speed of emergency maneuvers, ship movement, simulation method, technical failures
Abstrakt publikacji: The identification of navigational risks of accidents in fairways is a basic principle for the construction or modernization of waterways in restricted waters and when the conditions of safe operation change. The estimation of navigational risk requires the evaluation of the consequences of accidents occurring in fairways: grounding, impact against a vertical shore, port/offshore structure or moored ship. When determining the consequences of these accidents, it is necessary to know the emergency maneuvering area and the speed of the ship at the time of the accident. The method of ship movement simulation in real time was used to determine the parameters of emergency maneuvering areas and the speed of vessels during the maneuvers. The results of the simulation experiment include full form vessels (bulk carriers, tankers) with a capacity ranging from 5,000 DWT to 100,000 DWT. The presented results of simulation tests enabled the evaluation of probability and consequences of ships’ accidents in fairways resulting from technical failures of ships’ steering equipment, allowing to assess the navigational risk for ships sailing through different types of fairways (approach channels, port entrances and inner port fairways).
