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

Seaports

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.
Statistical Port -A statistical port consists of one or more ports, normally controlled by a single port authority, which is able to record ship, passenger and cargo movements.
Reporting Port-A statistical port for which statistics of inward and outward maritime transport flows are compiled.
Main port -A main port is a statistical port which has annual movements of no less than 200 000 passengers or recording more than one millions tonnes of cargo. For ports selected on the basis of only one of these cargo or passenger criteria, detailed statistics are required only for that transport.
Maritime coastal area (MCA) -A maritime coastal area is defined as a contiguous stretch of coastline, together with islands offshore. Within a country, an MCA is defined either in terms of one or more ranges of ports along its coastline, or in terms of the latitude and longitude of one or more sets of extremities of the coastal area. Riverbanks can be included. Normally the coastline of each country is allocated to a single maritime coastal area and the coastlines of more than one country may form a single maritime coastal area. There are some exceptions. For example, the USA is separated into a number of maritime coastal areas to cover its overall coastline. For some countries, two separate stretches of coastline may be counted as one maritime coastal area, as, for example, the Atlantic and Pacific coastlines of Mexico.
Carriage of goods and passengers by sea -The movement of goods and passengers using seagoing vessels, on voyage which are undertaken wholly or partly by sea. The scope of the Maritime Directive 2009/42/EC also includes goods:

  1. Shipped to offshore installations;
  2. Reclaimed from seabed and unloaded in ports.

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.
Nationality of registration of seagoing vessel (Flag state) -Every ship is entered in a registry (i.e. list) of ships. Registries are maintained by many countries, each having a set of rules regarding safety procedures, inspection schedules, manning numbers and nationalities for crew and officers, training requirements, etc. Ship-owners select which registry to use based on the balance between the relative cost implications of the rules of each registry and possible penalties from insurance assessments dependent on these rules.
Type of cargo- The type of cargo classification, set according to the UNECE - Codes for types of cargo, packages and packaging materials, Recommendation 21, Geneva, March 1986, describes how the goods are being transported in terms of the vessels being used and the port facilities required to handle them. It is therefore very different from the categories of goods classification.
Freight container-Special box to carry freight, strengthened and stackable and allowing horizontal or vertical transfers.

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.
Ro-Ro cargo -This means goods, whether or not in containers, on Ro-Ro units, and Ro-Ro units, which are rolled on and off the vessels, which carry them by sea.
Gross weight of goods -The gross weight of each consignment is the weight of the actual goods together with the immediate packaging in which they are being transported from origin to destination, but excluding the tare weight of containers or Ro-Ro units (e.g. containers, swap bodies and pallets containing goods as well as road goods vehicles, wagons or barges carried on the vessel). This measure of quantity is different from that used in trade statistics, namely the net weight of goods and different from statistics collected on other transport modes where the tare weight is included. Where goods are transported in a road goods vehicle, in a container, or other intermodal transport unit, the gross weight of the goods does not include the tare weightof the transport unit.
Gross tonnage -This means the measure of the overall size of a ship determined in accordance with the provisions of the International Convention on Tonnage Measurement of Ships, 1969.
Passenger Any person who makes a sea journey on a merchant ship. Service staff assigned to merchant ships is not regarded as passengers. Non-fare paying crewmembers travelling but not assigned and infants in arms are excluded.
Cruise passenger -This means a sea passenger making a sea journey on a cruise ship. Passengers on day excursions are excluded.
Cruise ship -This means a passenger ship intended to provide passengers with a full tourist experience. All passengers have cabins. Facilities for entertainment aboard are included. Ships operating normal ferry services are excluded, even if some passengers treat the service as a cruise. In addition, cargo-carrying vessels able to carry a very limited number of passengers with their own cabins are also excluded. Ships intended solely for day excursions are also excluded.
Cruise passenger excursion -This means a short visit by a cruise passenger to a tourist attraction associated with a port while retaining a cabin on board.

11.1. Quality assurance

The quality of statistical information and its production process is ensured by the provisions of the European Statistics Code of Practice and ESS Quality Assurance Framework

In 2007, a quality management system, conforming to the requirements of the international quality management system standard ISO 9001, was introduced at Statistics Lithuania. The main trends in activity of Statistics Lithuania aimed at quality management and continuous development in the institution are established in the Quality Policy. Monitoring of the quality indicators of statistical processes and their results and self-evaluation of statistical survey managers is regularly carried out in order to identify the areas which need improvement and to promptly eliminate the shortcomings.

11.2. Quality management - assessment

Data quality is in line with the accuracy, timeliness and punctuality, comparability and compatibility requirements. Before presenting survey results to users, the quality of the information obtained is analysed. Additional statistical quality checks are performed. The aggregated results are compared with the results of the previous period and the same period of the past year. Tendencies of vessels, goods and passenger traffic at the seaports in time series are analysed. When quality issues are encountered, the data providers are contacted and asked to investigate the problems. The data provider corrects statistical data and, if needed, sends back the corrections or new revised datasets.


12. Relevance Top
12.1. Relevance - User Needs

The main users of statistical information are State and municipal authorities and agencies, international organisations, the media, research and business communities, students, whose needs are satisfied without a breach of the confidentiality principle.

12.2. Relevance - User Satisfaction

From 2005, user opinion surveys have been conducted on a regular basis. Official Statistics Portal traffic is monitored, website visitor opinion polls, general opinion poll on the products and services of Statistics Lithuania, target user group opinion polls and other surveys are conducted. In 2007, the compilation of a user satisfaction index was launched. The said surveys are aimed at the assessment of the overall demand for and necessity of statistical information in general and specific statistical indicators in particular.

More information on user surveys and their results is available in section User surveys on the Statistics Lithuania website.

18.4. Data validation

A special program is used for statistical data entry, which searches for errors at the time of entry. The requirements for the validation of statistical data are provided in the technical task of the programming work for the statistical survey. Data validation takes place at the time when data is integrated into the statistical database. The formats, the codes and missing values of statistical data are checked. When uncorrectable errors or missing values are detected, the respondents are contacted. To ensure the quality of the statistical data, additional checks of the primary database are performed. The completeness and reliability of integrated data is checked, the relation between indicators is analysed.

18.5. Data compilation

After the checking of statistical data, they are aggregated to the required level of detail. More detailed description of the survey is described in Statistical survey on sea transport methodology (only in Lithuanian).
