3.1. Data description | |||
Maritime transport data refer to gross weight of goods (in tonnes), passenger movements (in number of passengers) as well as for vessel traffic (in number of vessels and in gross tonnage of vessels). |
|||
3.2. Classification system | |||
The following classifications are applicable: Maritime Coastal area: the nomenclature is based on the Geonomenclature (the country nomenclature for the external trade statistics of the Community and statistics of trade between Member States, originally drawn up by the Council Regulation (EEC) N°1736/75) in force in the year to which the data refer (RAMON: https://showvoc.op.europa.eu/#/datasets/ESTAT_Geonomenclature_2021_%28GEONOM_2021%29/data). Ports: the codes used are the official UN/LOCODEs, when they exist. If a port does not have an official UN/LOCODE a provisional (numeric) code is attributed to the port. As soon as an official UN/LOCODE is attributed by the United Nations Economic Commission for Europe (UNECE) to the port at the request of the competent national authority, the provisional (numeric) code is replaced by the final official one. In exceptional cases (see for example one-port transport or special aggregation for minor ports) permanent numeric codes are attributed to special locations or activities. The code list of UN/LOCODE is available by country through the following link: http://www.unece.org/cefact/locode/service/location.html. According to the relevant directive, Eurostat draws up a list of ports, coded and classified according to countries and maritime coastal areas. The list of ports is included in implementing legal acts and as such is published in the Official Journal of the European Union (the "official" list). The most recent list of ports published in the Official Journal is found in Commission Decision (EU) 2018/1007 Nationality of registration of vessels: the nomenclature used is the Geo-nomenclature (the country nomenclature for the external trade statistics of the Community and statistics of trade between Member States, originally drawn up by the Council Regulation (EEC) N°1736/75) in force in the year to which the data refer (RAMON: https://showvoc.op.europa.eu/#/datasets/ESTAT_Geonomenclature_2021_%28GEONOM_2021%29/data). The type of ship classification is harmonised with an internationally agreed International Classification of Ship by Type (ICST). The type of cargo classification, available in Directive 2009/42/EC, has been established in conformity with the United Nation ECE Recommendation N°21. |
|||
3.3. Coverage - sector | |||
Data refer to the activity of maritime ports connected with carriege of goods by sea-going vessels, onvoyages voyages undertaken wholly or partly at sea. Administrative ports are exluded. |
|||
3.4. Statistical concepts and definitions | |||
Main concepts used in this domain are the following and for more information on the concepts and methodology, please consult the Reference Manual on Maritime Transport Statistics.
Port -A place having facilities for merchant ships to moor and to load and/or unload cargo or to disembark and/or embark passengers to or from vessels, usually directly to a pier.
Bunkers and stores supplied to vessels shall be excluded from the scope. Seagoing vessel -Floating marine structure with one or more surface displacement hulls. In the context of the Directive, sea-going vessels are vessels other than those which navigate exclusively in inland waters or in waters within, or closely adjacent to, sheltered waters or areas where port regulations apply. Swap bodies are excluded. Although without internal volume flats used in maritime transport should be considered to be a special type of container and therefore are included here. For a fuller description, reference should be made to ISO 668 and 1496.The related term "container cargo" refers to containers, with or without cargo, which are lifted on or off the vessels which carry them by sea. Ro-Ro unit- This means wheeled equipment for carrying cargo, such as a truck, trailer or semi-trailer, which can be driven or towed onto a vessel. Port or ships' trailers are included in this definition. Classifications should follow United Nations ECE Recommendation No 21 'Codes for types of cargo, packages and packaging materials'. Live animals on the hoof are included. Vehicles being transported as cargo as opposed to a means of transport for freight are recorded in the separate headings of the Ro-Ro cargo classification, when they are rolled on or rolled off a vessel on their own wheels.

3.5. Statistical unit | |||
The data used in the domain are collected at port level. Data are collected from Executive Agency "Maritime administration" at the Ministry of transport, information technology and comunications at port level. |
|||
3.6. Statistical population | |||
Detailed data are provided for ports handling more than one million tonnes of goods or recording more than 200 000 passenger movements annually (Main ports). The other ports are required to provide summary data. However, detailed data may be included also for minor ports on a voluntary basis. |

The units used depend on the variables collected within each data set and are: gross weight of goods expressed in thousands of tonnes; number of passengers in thousands, number of vessels.
