    Opis:
    The paper is concerned with the analysis of under-keel clearance of ships based on real data from Szczecin Maritime Office. Using probabilistic method for UKC assessment give it possibility to create the distribution of under-keel clearance in several ship’s passages and in further step to determine the probability of ship’s grounding accident during the port approach. The results of using this type of model could be used in risk assessment of ships entering to the ports, therefore it is possible to used probabilistic model in Maritime Office employees’ everyday decision making practice. Research results present verification of probabilistic model, based on data from Vessel Traffic Service database and probability of touching the bottom during ships’ passages on Swinoujscie - Szczecin waterway. Moreover there are presented examples of these situations when entering to the port for analysed ships is not allowed according to the model.

    Opis:
    The purpose and scope of this article is to present the best marine practices used to determine the ship’s domain depth (compared to the safety depth parameter in ECDIS) and the safest and best possible speed (also known as optimal speed) of the ship in restricted sea areas limited by the depth of navigation waters. The author also presents a method that can be used to estimate the safe speed of a ship in shallow waters and the so-called navigational risk factor (specified in the range from 0 to 1), using the safety depth parameter specified in ECDIS based on the analysis of a three-dimensional model of the ship’s domain. The essence of the method proposed in this paper is a systematic approach to the operation of a seagoing ship in the aspect of assessing its navigation safety (navigational risk factor) when manoeuvring in restricted sea areas, in particular in shallow waters including navigable canals and fairways.

    W artykule zaproponowano sposób oceny bezpieczeństwa żeglugi (ryzyka nawigacyjnego) kontenerowców klasy PS, takich jak „Emma Maersk”, w akwenie ograniczonym Zatoki Gdańskiej z wykorzystaniem przestrzennego modelu domeny statku. Istotą proponowanych w pracy metod jest systemowe ujęcie eksploatacji statku morskiego w aspekcie oceny jego bezpieczeństwa podczas manewrów podchodzenia do terminalu kontenerowego DTC Gdańsk Port przy działaniu różnych zakłóceń zewnętrznych.
    In this paper author presents the methods that can be used for estimating the safety of shipping (navigational risk) in the restricted sea areas of the Gulf of Gdańsk by means of a three- -dimensional model of ship’s domain specified for the PS Class container vessels ‘Emma Maersk’. The essence of the method suggested in the thesis is the systematic approach to a sea vessel operation in the aspect of estimating its safety while approaching DCT terminal in Gdańsk Port Północny in divergent exterior conditions.

    Opis:
    The continuing surge in commercial vessel sizes is putting increasing pressures on the world’s port authorities to adopt effective expansion strategies to ensure that their asset is able to meet growing capacity demands. Among the key challenges is to assure that correct strategic planning and operational measures are adopted to guarantee safe and efficient traffic not only through its shipping channel, but also at the port berthing facilities. DHI and FORCE TECHNOLOGY have collaborated to develop a novel physics-based vessel traffic management system named NCOS ONLINE. It is capable of taking into account of any relevant vessel constraints such as under-keel clearance (UKC), maneuverability and berth configuration that may constrict the movement of vessels through the channel or operability at berth, facilitating scenario planning and capacity assessment of proven unparalleled accuracy. The system incorporates the accuracy of high-end Full Mission Bridge Simulators with regards to vessel response under power and at berth. The underlying computational engines uses a powerful 3D panel method for vessel response calculations in combination with highly detailed environmental data such as wind, waves and hydrodynamics (water level and currents) simulated by use of MIKE Powered by DHI’s recognized and scientific based computational models. The modular and integrated framework-based system has already been adopted by numerous port authorities, terminal operators and pilots worldwide for strategic port planning, design and 24/7 operational vessel traffic management. The paper focus on presenting the underlying equational framework and validation of the underlying physical response engines and provide a brief introduction to how they are integrated and operated through a series of user-friendly web dashboards.

    Opis:
    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.

    Opis:
    Sea–river ships can connect the area inside of land with oversea places without of indirect trans- shipment. In many cases the sea-river ships move on waterways (natural and artificial) inside of land for hundreds kilometres. Navigation in inland waters has to meet the same requirements as those for pilot navigation. This is due to the relations between the ship size and other objects on water area. These ones caused the navigation more hard then on open seas. The paper presents the criterion of safety assessment of navigation during sea-river ships manoeuvring ship in inland waters.
