Pilot-operations of the multifunctional marking vessels are being successfully conducted


After the baptism ceremonies, the multifunctional marking vessels in Slovakia, Hungary, Croatia, Bulgaria and Romania are being tested during the marking pilots to improve future marking operations by waterway administrations.

The start of the pilot operation of the multifunctional marking vessels in Slovakia, Hungary, Croatia, Bulgaria and Romania in the frame of FAIRway Danube has been improving efficiency of fairway marking operations and enhances navigation conditions along critical sections.


The marking vessels are equipped with state-of-the-art technology for a facilitated navigation experience and for improved positioning of buoys. The marking results are published by waterway administrations in various formats, such as using the Danube FIS Portal (www.danubeportal.com) to publish bottleneck information.


During the marking pilots, the newly procured and upgraded vessels are being tested to improve and modernise the waterway administrations’ marking operations and the subsequent information provision. Another reason was to establish a solid and harmonized data basis for management decisions regarding follow-up projects and initiatives. Marking results are being analysed and concentrate on the availability of signs, accuracy of their position and information provision.

The respective pilot operations are being performed in the frame of the FAIRway Project:


  • Slovakia: The new marking vessel is in pilot operation as of August 2019
  • Hungary: The 3 upgraded marking vessels are operating as of March 2020
  • Croatia: As of March 2019, the new marking vessel is in operation
  • Bulgaria: The marking vessel is in pilot operation as of October 2018
  • Romania: The marking vessel started its pilot operation in June 2019
