SAFERDANUBE Satellite Assistance for Danube Navigation

You are here

SAFERDANUBE will help the Romanian River Administration of the Lower Danube (AFDJ) in improving safety and fluency of the naval traffic during the winter and summer periods where ice banks/sand banks appear in the Danube. This is required by AFDJ to comply with their obligations with the Ministry of Transports, Constructions and Tourism in accordance with Government, as stated in the decree HGR 492/2003. In addition, the project expects to demonstrate how the use of Satellite Communications can be a competitive alternative to standard mobile telephony for vessels navigating along the Danube.

To achieve this objective, the project envisages the design, development, integration and pre-operation of a service to detect, monitor and distribute obstacles information (i.e. ice and/or sand banks) in the Danube river in near-real time. The service will be based on Satellite Earth Observation (Very High Resolution Synthetic Aperture Radar) information products will be accessed from the river vessels via Satellite Communications and delivered through a web platform, integrated with current AFDJ data products or directly transmitted and integrated with vessels’ own Satellite Navigation systems. The system will be installed and validated on operational vessels of both AFDJ and of Transport Companies during the pilot demonstration phase at the end of the project.

Users and their needs

Navigation on the Danube River is limited by the presence of sand banks(dry periods) and ice banks(winter), phenomena that have an important impact on navigation safety and continuity and effectiveness of goods and passengers’ transport operations. Users claimed about: lack of coverage in some areas, ships positioning too slow, signalling updates too slow ships tracking and positioning , fairway signalization, fast data receiving in areas with gsm coverage

Presently the updates of the maps are periodical, not in real time and could be improved using the solution envisaged.

The needs are: increasing the transportation safety; transportation efficiency; in winter there are areas not presently monitored  and  ice formations can occur with obvious danger for transiting ships; in summer , with low level of Danube River, it is a need for correct assessment of distances to floating signals and for navigation maps updating accordingly; monitoring the areas with difficulties, where ships may be stranded; monitoring of the shorelines and buoys position; islands monitoring; traffic monitoring; erosion of banks and hydraulic works monitoring.

Transport companies

Authorities involved in assurance of safeness of naval traffic and inland waterways optimisation.

The project is addressed to all Danube countries: Romania, Bulgaria, Serbia, Hungary, Slovakia, Germany, Austria etc with similar problems that confronted. Other target users are: authorities, transportation companies, research institutes and training centres.

Service/ system concept

The basic service is the detection of location, extent and shape of the sand and ice banks. The added-value brought through the solutions includes Reliable and fasr access to information (including EO data) through satellite communications and navigation. This basic activities leads to a set of possible "services": indicate the optimal route to have a fluent trip, indicate if there are also other ships blocked because of the phenomena, etc.

The service will provide a continuous monitoring during the emergency periods  on a specific area in order to avoid collision or navigation problems due to the presence of sand or ice banks. The service will be used during the alert period, summer or winter, in order to assure the correct data providing representing the area of interest. Within "normal" periods the service will provide a regular two times per month monitoring of the area of interest using webservices.

Space Added Value

The added-value includes improving the functionality of existing navigation systems, accuracy of sailing management information, dissemination of information, integration with the vessel on board system, a model for sustainability of the service, satellite communications and navigation systems.

 It will be easier to define the extent of the area of interest and move its geo-localization above the territory. Selecting the VHR SAR sensors within the range of EO systems take opportunities disregarding the visibility conditions and leveraging on the known capabilities of Synthetic Aperture Radar sensors, reduce the effort on the delineation of navigation obstacles over the river surface. It will be possible to grant multiple daily opportunities of acquisitions and so to widen the portfolio of higher value product available.

Product Benefits

The RORIS system (Romanian River Information System), is the national system for traffic management..The updates are periodical, not in real time. This will be improved using the new solution.

The advantage given by the project will be the integration and extension of data base already managed with a more detailed location and shape information related to river obstacles and providing alternatives for the access channels and interfaces, specific and effective for this service.

The added-value that will be brought: improving functionality of existing navigation systems, accuracy of sailing line management information toward ships,, dissemination of information about the capabilities and opportunities for the stakeholders to exploit space assets and reliable and fast access to information.

Product Features

The service offered: the web service and the integration of the system with ECDIS, integration in standard on-board navigation tools, effectiveness and usefulness of provided data.

Another channel will be used to disseminate the information. This tool is SeeMyENC, it “allows users to zoom, pan within a chart, select different symbology & colors, select pick reports and analyze the ENC data.”

The results will be also available via the provided WebGis Interface.

All the specification will be followed during the data integration process in order to assure the complete respect of all the specification and a full compliancy.

 

Current Status

The project was concluded in March 2018.  The team is working both with Authority and Commercial stakeholders to define the next phase. The Romanian River Administration of the Lower Danube (AFDJ) Authority  will advocate the upgrade of the river navigation maps in order to allow the visualization of the obstacles  of the navigation (i.e. sand and ice bank). On the commercial side, dialogues are taking place with different shipping companies which would like to combine SAFERDANUBE with the their existing fleet management  system.
