3.1. Data description

Inland waterway transport statistics provides information on the volume and performance of freight transport on EU inland waterway network. They are reported on the basis of the "territoriality principle" which means that each country reports the loading, unloading and movements of goods that take place on its national territory, irrespective of country of origins of undertakings or place of first loading and final unloading.

 

The full data provision obligation includes:

  • annually: goods transport by type of goods, by nationality of vessels and by type of vessel as well as container transport by type of goods;
  • quarterly: goods and container transport by nationality of vessels.

In addition, the legislation foresees voluntary annual data on vessel traffic. Voluntary annual data on the transport of dangerous goods and the number of accidents has been agreed with the reporting countries.

 

In summary, the statistics transmitted to Eurostat on inland waterway transport:

  • Transport of goods (annual and quarterly mandatory data provision);
  • Vessel traffic (annual voluntary data provision);
  • Transport of dangerous goods (annual voluntary data provision)
  • Number of accidents (annual voluntary data provision).
3.2. Classification system

Country and NUTS codes

Territorial units like reporting country and regions for loading/unloading are coded according to NUTS classification for those units covered by NUTS Regulation and to ISO 3166 for the rest (e.g. territorial units outside EU). The used version of NUTS always corresponds to the version in use and no conversion to previous version is required. For instance, NUTS 2006 is used for 2008 to 2011 data, NUTS 2010 for 2012 to 2014 data, NUTS 2013 for 2015 to 2017 and NUTS 2016 for 2018 until next NUTS Regulation.

The level of detail is either NUTS0 – for reporting country – or NUTS2 (basic regions, 4 digits) – for regions. When using ISO 3166 and 4-digits level coding is required (e.g. for regions outside EU), the two-digit ISO code followed by “ZZ” is used.

Goods classification

Prior to 2007, the types of goods reported as being transported by inland waterways were those defined by NST/R (Standard Goods for Transport Statistics). In 2007 only, the type of goods has been reported according either to the NST-2000 classification or to the NST/R classification. From 2008 onwards, only the NST2007 classification is valid as set out in Commission Regulation 1304/2007 amending Regulation 1365/2006 with respect to the establishment of NST2007 as the unique classification for transported goods in certain transport modes.

Dangerous goods are classified according to the European Agreement Concerning the International Carriage of Dangerous Goods by Inland Waterways (ADN). The classes are the following:

Class      Denomination

1             Explosive substances and articles
2             Gases
3             Flammable liquids
4.1          Flammable solids, self-reactive substances and solid desensitised explosives
4.2          Substances liable to spontaneous combustion
4.3          Substances which, in contact with water, emit flammable gases
5.1          Oxidising substances
5.2          Organic peroxides
6.1          Toxic substances
6.2          Infectious substances
7             Radioactive material
8             Corrosive substances
9             Miscellaneous dangerous substances and articles

3.4. Statistical concepts and definitions

The definitions covering the main concepts used in this domain are included in Article 1 and Annex II to Regulation 425/2007. The main definitions are as follows:

Navigable inland waterway: A watercourse, no part of the sea, which by natural or man-made features is suitable for navigation, primarily by inland waterway vessels. This term covers navigable rivers, lakes, canals and estuaries.

Inland waterway vessel: A floating craft designed for the carriage of goods or public transport of passengers, which navigates predominantly in navigable inland waterways or in waters within, or closely adjacent to sheltered waters or areas where port regulations apply.

Nationality of the vessel: The country in which the vessel is registered.

Inland waterways transport: Any movement of goods using inland waterways vessels, which is undertaken wholly or partly in navigable inland waterways.

National inland waterways transport: Inland waterways transport between two ports of a national territory irrespective of the nationality of the vessel.

International inland waterways transport: Inland waterways transport between two ports located in different national territories.

Transit inland waterways transport: Inland waterways transport through a national territory between two ports both located in another national territory or national territories provided that in the total journey within the national territory there is no trans-shipment.

Inland movement: any movement of goods and/or passengers to and from inland ports connected by water routes which may be made navigable by one or more lock structures.

Inland waterways traffic: Any movement of a vessel on a given navigable inland waterway.

Types of vessels:

  • Self-propelled barge. Any powered inland waterways freight vessel, other than self-propelled tanker barges.
  • Barge not self-propelled. Any unpowered inland waterways freight vessel, other than not self-propelled tanker barges. This category includes towed, pushed and pushed-towed barges.
  • Self-propelled tanker barge. A self-propelled barge intended for the transport of liquids or gases in fixed tanks.
  • Tanker barge not self-propelled. A barge not self-propelled intended for the transport of liquids or gases in fixed tanks.
  • Other goods carrying vessel. Any other known or unknown kind of inland waterways freight vessel intended for carrying goods not defined in the previous categories.
  • Seagoing vessel. A vessel other than those, which navigate predominantly in navigable inland waterways or in waters within, or closely adjacent to, sheltered waters or areas where port regulations apply.

Containers: A freight container means an article of transport equipment:

1. of a permanent nature and accordingly strong enough to be suitable for repeated use;

2. specially designed to facilitate the carriage of goods by one or more modes of transport, without intermediate reloading;

3. fitted with devices permitting its ready handling, particularly its transfer from one mode of transport to another;

4. so designed as to be easy to fill and empty;

5. having a length of 20 feet or more.

 

The size of containers is reported according to four categories:

1) 20 Foot ISO containers (length of 20 feet and width of 8 feet)

2) 40 Foot ISO containers (length of 40 feet and width of 8 feet)

3) ISO containers over 20 feet and under 40 feet in length

4) ISO containers over 40 feet long

Containers smaller than 20 feet are reported under Category 1.

Containers of unknown size are reported under Category 3.

Inland waterways accidents: specific, identifiable, unexpected, unusual and unintended external event caused by, or in connection with, the operation of an inland waterways vessel resulting in an inland waterways casualty or incident which occurs at a particular time and place, without apparent cause but with marked effect.

By definition suicides are excluded, as they are a deliberate act. Because of their importance, suicide statistics should be collected separately. Terrorist and criminal acts are excluded.

Inland waterways accidents involving the transport of dangerous goods: An inland waterways accident involving a vessel carrying any of the classes of dangerous goods defined by the ADN classification

Inland waterway traffic: any movement of an IWT vessel on a given IWT network.When a vessel is being carried on another vehicle, only the movement of the carrying vehicle (active mode) is taken into account.

Inland waterway journey: any movement of an IW vessel from a specified point of origin to a specified point of destination.
