River transport on the Danube for heavy loads
For loads too heavy or too large for the roads along the whole route, the Danube is often the option that makes the transport possible. A barge can carry pieces of hundreds of tonnes without road permits over hundreds of kilometres, leaving road transport only for the ends: from the factory to the port and from the port to the site.
At a glance
- When
- very heavy or very large pieces, routes close to the water
- Connection to the sea
- the Danube–Black Sea Canal, towards Constanța
- Road legs
- AST permit for the road sections
- Public example
- the 788 t turbine for Mintia
When river transport makes sense
Transport on the Danube makes sense when the piece is too heavy or too large for the roads along the whole route, when the bridges on the road route have restrictions or when the origin and destination are close to a river port.
On the water no road permits are needed over hundreds of kilometres, but the transport is slower and depends on the water level. The road legs, from the factory to the port and from the port to the site, still need an AST.
- transformers, generators and turbines;
- very heavy reactors and columns;
- large structures and modules;
- components for sites close to the Danube.
Public examples of river transport
| Public example | What was transported | How |
|---|---|---|
| Mintia power plant (2025) | 788 t turbine | from the USA across the ocean, then on the Danube and the Tisza to the landing stage near Szeged; 44 km by road to Nădlac and 245 km in Romania |
| Constanța – Oltenița (2017) | 230 t transformer, 11.40 × 4.20 × 4.30 m | loaded onto a barge in the Port of Constanța directly on the modular trailers and unloaded at the river port of Oltenița, on a ramp with a gradient of about 10% |

Ports and transhipment
Constanța is connected to the Danube by the Danube–Black Sea Canal. On the Danube, ports such as Galați, Brăila, Giurgiu, Oltenița or Drobeta-Turnu Severin can serve as transhipment points, depending on the capacity of the quay and the equipment available.
Transhipment is done by crane or via a ramp, with the modular trailers driving onto and off the barge together with the piece.
What we check
- The water
- the level and draught along the whole route
- The quay
- bearing capacity and access
- The ramp
- the gradient and the condition of the access road
- The road
- AST permit for the road legs
What affects the timeline
The level of the Danube changes from one season to the next, and at low water the permitted draught decreases. We plan river transport with a time buffer and check the level forecasts before loading. The lock schedule, the availability of barges and tugs and the permits for the road legs complete the schedule.

Frequently asked questions
Is river transport cheaper than road transport?
For very heavy pieces, often yes, because it avoids permits, reinforcements and escort over long distances. For ordinary loads, the transhipments can make the river option more expensive. We price both options.
What happens when the Danube is low?
The permitted draught decreases, and the barge can load less or has to wait. That is why we plan with a time buffer and check the water level before loading.
Can you organise the whole chain, including the road sections?
Yes. We coordinate the road transport to the port, the transhipment, the barge and the road transport from the port of unloading to the site.
