Short-term excursion for the students of Faculty of transport and traffic sciences was organized by the Department of water transport in collaboration with the Department of water transport of Faculty of operation and economics of transport and communications (FPEDAS) from Žilina (Slovakia). Three-day long excursion form June 11 to June 13, 2018 was organized within CEEPUS III programme by Assoc. Prof. Andrej Dávid, Ph.D and Vlatka Stupalo, D.Sc.
First day the students visited University of Žilina kampus and FPEDAS navigation simulator at the Department of water transport (June 11, 2018) where the host were Martin Jurkovic and Tomas Kalina. The students were able to experience working on the bridge simulator for inland waterway navigation (Figure 1 and Figure 2) by navigating the cargo ship on the section of Danube that passes through city of Bratislava.
They also visited Department of railway transport (Figure 3 and Figure 4) where they were welcomed by dr. Pavol Meško who show them model of railway network and explained and demonstrated to them how it operates. On this model students were able to perform exercises.
On the same day Public Intermodal Transport Terminal Žilina (Figure 5 and Figure 6) was also visited where hosts were Lubica Franova and Vladimir Polakovic. The terminal is in the ownership of the Slovak Republic and in the administration of Železnice Slovenskej republiky (ŽSR) Bratislava. The terminal wasn’t at that time open for traffic, but the plan is for the terminal to be publicly accessible intermodal transport terminal owned by the state, while the national railway infrastructure manager (ŽSR) will execute the ownership rights for the State.
Second day the Danube cargo river port of Bratislava was visited where the host was Robert Hencek from Slovenská plavba a prístavy a.s. (Figure 7 and Figure 8). Port of Bratislava offers services of unloading and loading of ferro materials, bulk, general, ro-ro and liquid cargo (PMO) and of overweight and over dimensional cargo.
Also, students visited river passenger terminal (Figure 9 and Figure 10) where they embarked river boat Žilina. Hosts were Marek Povazan and Jaroslav Dunaj. Student sailed with passenger ship on Danube river alongside Bratislava. Route of sailing is shown on the Figure 11.
Last day the visit to Danube lock at Gabcikovo was organised. Hosts were Vladimir Holcik and Karol Bakos.
First they visited lock chambers at Čunovo (Figure 12) and Čunovo Water Sports Centre – Divoká voda (Figure 13).
Then student visited lock chambers at Gabčikovo, which are based in watery sandy gravels which reaches a depth of over 300 m. Part of the Gabčikovo Waterworks (GWW) is a hydroelectric power plant which annually produces 10% of total electricity consumption in Slovakia. Gabčíkovo Waterworks (GWW) consists of the following energy parts:
- hydropower plant in Gabčíkovo (HPP Gabčíkovo)
- hydropower plant in Čunovo (HPP Čunovo)
- small hydropower plant in Mošon (SHPP Mošon)
- small hydropower plant in Mošon II (SHPP Mošon II)
- small hydropower plant in S VII (SHPP S VII)
- small hydropower plant in Dobrohošt (SHPP Dobrohošt)
Production at the water structure Gabčikovo manages and operates state enterprise Vodohospodárska výstavbam which sales dispatching is in Žilina. HPP Gabčíkovo is the biggest hydropower plant in Slovakia which was put into operations between 1992-1995. It uses hydro energy potential of the river Danube. River Danube is the longest river in European Union and it has the second largest river delta (after Volga) in Europe.
At Gabčikovo student visited Control centre of the hydropower plant (Figure 14 and Figure 15) from which the whole technological process of generating electricity is remotely managed and controlled as well as the turbo-generators with Kaplan turbines. HPP Gabčíkovo is equipped with eight turbo-generators with Kaplan turbines with four shovels of the outer wheel. Each turbine weighs 1,225.5 tons. Depending on the gradient (16 – 24 m), the flow through the turbine is 413 up to 636 m3/s water and output of 90 MW.
Students also visited Control centre of lock chambers (Figure 16 and Figure 17) where there were able to see how operation of the passing of the ship through lock chambers is managed.
