Title: A Method of navigational information display using augmented virtuality

Author/Authors: Rafał Gralak

Place of publication: Journal of Marine Science and Engineering, 2020 8(4), 237, pp.1-18

Year: 2020

Keywords: marine simulation, augmented virtuality, mixed reality, decision support system

Abstract: The preliminary research experiments described herein were aimed to choose an appropriate mixed reality technology for the construction of navigational information display method to be used onboard ships in restricted waters. The method assumes a possibly faithful representation of the environment and the actual navigational situation on a spatial decision support system (SDSS) interface during ship navigation and maneuvering in restricted waters. The 
paper also presents the architecture and process of building a SDSS, where the method of navigational information display using augmented virtuality was applied.

Title: Areas of emergency maneuvers and the navigational risk of accidents in fairways due to ship technical failures determined by the ship movement simulation method

Author/Authors: Stanisław Gucma, Rafał Gralak, Bartosz Muczyński

Place of publication: Zeszyty Naukowe Akademii Morskiej w Szczecinie, vol.61(133)2020, pp. 39-47

Year: 2020

Keywords: navigational risk in fairways, consequences of navigational accidents, areas and speed of emergency maneuvers,ship movement, simulation method, technical failures

Abstract: 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).

Place of publication: Zeszyty Naukowe Akademii Morskiej w Szczecinie, 57(129)2019, pp. 49-55

Year: 2019

Keywords: port manoeuvring, simulation of ship movement, manoeuvring safety, tug assistance, determination, minimum safe pull

Abstract: The article presents a simulation method for determining the minimum safe pull of tugs assisting in port
manoeuvres. The method can be used to determine the relationship between the minimum safe pull, understood as the tension on the line, of the assisting tugs and the overall length, cargo capacity or net capacity of ships manoeuvring in
a given port under allowable hydrometeorological conditions. The method was verified through simulated tests of gas tankers’ entry, turning and berthing at the LNG terminal of Świnoujście.

Abstract: The presented method for defining the conditions of safe operation of marine ferries in ferry terminals allows
verification of shipowner ferry designs. In the first stage of this method, simulations are used to determine the allowable wind speed. The second stage comprises simulations of ferry berthing aimed at defining safe manoeuvring areas, the energy of berthing impact and propeller stream speeds at allowable wind speeds. The method was used in the design of a 228 m long hybrid ferry.

Place of publication: Scientific Journals of the Maritime University of Szczecin

Year: 2018

Keywords: optimization, ships traffic, Simulation method, seaport parameters, container port, safety of manoeuvring

Abstract: The article presents an original two-stage simulation method for the optimization of seaport parameters.
Presentation of the method is based on example of parameter optimization of the outer container port in Świnoujście. Presented method uses two limitations of the objective function related to safety of manoeuvring and mooring of ships.
It consist of two stages, first one is carried out for the parameters defined in the preliminary stage of design. On the basis of results from this stage, layout and other parameters of port waterways can be adjusted to satisfy
assumed safety criteria. The second stage uses the parameters established in the first stage. It allows for small adjustments which will not change the safety of manoeuvring. The result of second stage is optimal parameters of the
examined port waterways.

Abstract: Inżynieria ruchu morskiego jest dyscypliną zajmującą się jakościowym i ilościowym opisem ruchu
jednostek pływających na akwenach ograniczonych w aspektach bezpieczeństwa nawigacji i efektywności żeglugi. Opracowywane metody i procedury inżynierii ruchu morskiego znalazły szerokie zastosowanie przy projektowaniu morskich dróg wodnych, portów, statków oraz warunków ich bezpiecznej eksploatacji. Projektowanie w inżynierii ruchu morskiego utożsamiane jest z następującymi podstawowymi zadaniami:

• optymalizacja parametrów budowanych i modernizowanych systemów morskich dróg wodnych;

• określenie warunków bezpiecznej eksploatacji statków na drogach wodnych;

• optymalizacja parametrów statków przewidzianych do eksploatacji na określonych drogach wodnych. Opisane w książce metodologia i metody projektowania różnego rodzaju dróg wodnych ich systemów oraz promów morskich zostały opracowane w oparciu o odpowiednie rozwiązania stosowane w inżynierii ruchu morskiego. Metody te bazują na modelach deterministycznych i probalistycznych procesu ruchu statków, modelowaniu matematycznym i symulacji
komputerowej ruchu statków na morskich drogach wodnych.
