Given the uncertainty of the navigating conditions on the Danube River, the hydrological situation on the Bulgarian leg of the river is predicted using ARIMA methods. The forecast is based on statistical daily hydrological data for a period of five years. A mathematical routing model is developed under the condition that it is not possible for a self-propelled vessel to continue its voyage due to draft limitation. Options including waiting for navigation opening, partial lightening on a barge, and a complete or partial modal shift to rail or road transport through an alternative port are considered. An acceptable option is determined, taking into account the additional costs and transit time. A routing simulation is made using SPSS software.

Global Navigation Satellite Systems (GNSS) are increasingly used as the main source of Positioning, Navigation and Timing (PNT) information for inland water navigation. In order to enable automated driving and facilitate driver assistant functions, it becomes of crucial importance to ensure high reliability and accuracy of the GNSS-based navigation solution, especially in challenging environments. One challenging phase of inland waterway navigation is bridge passing which leads to non-line-of-sight (NLOS) effects such as multipath and loss of tracking. This work presents a Precise Point Positioning (PPP) based algorithm in a two-antenna system where one antenna is at the bow and the other is at the stern. Additionally, gyroscope data from an IMU is used. In contrast to a separated position calculation of the two antennas, only one antenna position is estimated and the other is derived from the baseline between the antennas. This allows for accurate positioning even if one antenna does not receive any GNSS measurements. The presented scheme is evaluated using real measurement data from an inland water scenario with multiple bridges. In comparison with a standard PPP scheme as well as an RTK algorithm, the presented approach shows clear advantages in challenging scenarios.

The society’s main trend for globalisation requires the restructuring of the global transport system as a whole. The ‘Dnieper region’ is no exception, as it needs changes in its practice of organising and managing its process of cargo delivery in accordance with the current trends. This paper considered the main solution directions of this problem in the aspect of ‘container on barge system’ transportation in accordance with the potential of the region. Based on international experience, the competitiveness of the container on barge system can be ensured by applying the different forms of cooperation between the business-players. In the case of horizontal cooperation, it’s raising the problem of distribution of structural elements of the container on barge system during the container-flows adoption. So, the paper proposed the mathematical decision to maximise the use of the linear ship's characteristics by the barge’s loading capacity and by the tug’s engine power.

River cruising is well developed in Europe, particularly in the western, central, and some southern regions, and river tourism has expanded visibly during the current decade. A number of highly attractive tourist destinations are located upon rivers, the prime rivers used for cruises being the Danube, Rhine, Maine, Elbe, Loire, and Seine. The topic of this paper is an analysis of European river cruising and the determinants affecting this tourist product. In particular, the paper analyses the current state of river cruising in Poland, as well as the threats and opportunities that act as drivers for such cruising activity. This paper aims to identify and rank the main problems facing river cruising in Poland compared with prime destinations in Europe. River cruising has great potential, but it requires the removal of barriers and the addition of primary infrastructure.

The main subject of this research was to identify recent basic trends in the development of inland waterway transport in the EU as well as to evaluate this from both EU transport policy objectives and logistics markets’ requirements. For this purpose, classical statistical and economic analysis methods as well as the documentation research method were used. The basic threats and barriers to the development of inland waterway transport are indicated, as well as various actions necessary to limit or eliminate them. An attempt was also made to assess the opportunities and prospects for the development of this transport mode in the next decade in the context of the development of the broader EU transport market. The main objective of this research was to perform a market assessment of the development prospects of this mode of transport in the era of dynamic developing logistic customer service standards, as well as progressive globalization and the 4th industrial revolution (digitalization). In this respect, political versus market-oriented scenarios of the development of EU inland shipping were analyzed and evaluated. The conclusions relate to the ongoing and upcoming modal shift on the EU transport market as well as regulatory measures undertaken by the EU.

The article presents an analysis of offenses in inland navigation in 2013-2017, based on the number and reasons for issuing fines by Offices of Inland Navigation in Poland. In the investigated period, in Poland, over 1,300 fines were issued on the basis of five articles of the Act of 21st of December 2000 on Inland Navigation. Based on the collected data, the most common reasons for punishing crews of inland vessels were determined and the impact of these offenses on the safety of inland navigation in Poland was identified. In addition, recommendations for changes in the classification of offenses were presented due to the too wide spectrum of individual articles, which adversely affects the ability to interpret the most common offenses and makes it difficult to assess the causes and effects of their occurrence.

The use of SBAS corrections for navigation, in both coastal waters and inland waterways, has already brought the attention of many European authorities, which are interested in its potential to complement/replace their DGPS radio beacon networks. The European GNSS Agency (GSA) has an active long-term trajectory working to foster the EGNOS adoption in maritime through the launch of several actions whose results will pave the way for the provision of maritime EGNOS services. In this line, GSA awarded the consortium ALG-Indra, ESSP and Alberding with the Specific Contract GSA/OP/07/13/SC24 ‘Support to Maritime Service Providers for the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations’. The main objective of this Specific Contract is to demonstrate the operational performance of the transmission of EGNOS corrections converted to Differential GPS corrections over the existing transmission infrastructure (AIS base stations/IALA beacons) in the Maritime and Inland Waterways (IWW) domains, while providing a detailed cost benefit analysis of the solutions proposed. This service may complement the current GNSS augmentation services exploiting synergies and benefiting from the current infrastructure and standards, facilitating the adoption of EGNOS by maritime and inland waterways authorities. Furthermore, the service has no impact at user level since the DGNSS corrections are transmitted over the existing infrastructure, in the same format and implementing the same integrity mechanisms required for traditional IALA beacons ([1]). This project will allow the maritime and IWW service providers to have a clear understanding about the technical, operational and economic feasibility of the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations.

W artkule przedstawiono koncepcję zaopatrzenia w paliwo drogą wodną elektrowni Dolna Odra. Zbudowana w latach 70 elektrownia zaopatrywana jest w węgiel kamienny z polskich kopalń przy wykorzystaniu transportu kolejowego. Wobec korzystnego położenia w pobliżu Odry Wschodniej rozpatrywano możliwość zaopatrywania zakładu drogą wodną. Wymagałoby to budowy portu wodnego. Przeprowadzone wcześniej badania w pełni potwierdziły taką możliwość. Dodatkowym argumentem za budową portu są plany rozwojowe w oparciu o budowę bloków energetycznych zasilanych gazem. Wobec wejścia do eksploatacji Terminala Gazowego LNG w Świnoujściu jest możliwość zaopatrywania elektrowni tym gazem poprzez transport wodny gazu skroplonego. Byłaby to alternatywa do budowy gazociągu lądowego w związku z planowanymi dostawami gazu z Morza Północnego za pomocą gazociągu Baltic-Pipe, którego uruchomienie planowane jest na 2022 rok.

The paper presents the concept of supply for the Dolna Odra power plant by waterways transport. It was built in the 1970s, The power plant based on hard coal from Polish mines using rail transport. In view of the favorable location near the Eastern Odra, the possibility of supplying the plant by waterways was considered. This would require the construction of a water port. The tests carried out previously fully confirmed this possibility. An additional argument for the construction of the port are development plans based on the con-struction of power units powered by gas. In view of the entry into operation of the LNG Gas Terminal in Świnoujście, it is possible to supply the power plant with this gas by means of water transport of liquefied gas. It would be an alternative to constructing a land gas pipeline in connection with planned gas deliveries from the North Sea with the use of the Baltic-Pipe gas pipeline, scheduled for operation in 2022.
