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 | |||
The Maritime Transport Survey refers to the carriage of goods and passengers by seagoing vessels. Carriage of goods and passengers means the movement of goods and passengers using seagoing vessel, on voyages which are undertaken wholly or partly at sea. The data collected from ELSTAT are ports’ data. This survey covers all the sea ports of the country and is conducted in a monthly basis. Detailed information is collected on cargo and passenger (reporting port, type of cargo, gross weight in tones, description of goods, direction of movements whether inwards or outwards, port of loading and unloading, number of full and empty containers and ro/ro units number of embarked and disembarked passengers, number of cruise passengers on a cruise passenger excursion). Also detail information is collected on the vessel (number, gross tonnage or deadweight, type and country or territory of vessels). The sector coverage is based on NACE rev.2 50.10 Sea and coastal passenger water transport - 50.20 Sea and coastal freight water transport. |
|||
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.

The Hellenic Statistical Authority (ELSTAT) aims to ensure and further improve the quality of statistics produced and maintain the confidence of users in them. This is achieved through the Quality Policy of ELSTAT which is posted on the website of ELSTAT and is available at the following link: http://www.statistics.gr/en/policies Quality checks and validation of data are carried out through the whole compilation process, from the data collection stage to the final compilation of tables. First of all, well trained and experienced staff is utilized for all stages of process, that is, for data collection including communication with port authorities and enterprises, initial checks, data entry and final checks. Data are validated either before or after data entry to the data base of ELSTAT by means of logical checks. Basic quality checks are applied, along with checks for completeness, accuracy and consistency of the correlating variables. If significant discrepancies are identified in comparison with the corresponding quarters of the previous years, a further investigation is conducted in collaboration with data providers in order to justify or confirm the data. |
|||
11.2. Quality management - assessment | |||
Maritime transport statistics data are considered to be highly reliable data, after the necessary logical checks conducted in all the phases any errors are duly corrected and the necessary adjustments are made. They are compiled in accordance with recommendations that are provided in the relevant European Directive and the Reference Manual. The survey meets all the criteria of consistency, comparability, accuracy and punctuality. |
|
|||
12.1. Relevance - User Needs | |||
The data of maritime transport statistics meets national needs as well as needs to fulfill the obligations arising from the implementation of European Directive. The main national users are Ministries, researchers, economic analysts, students, Universities and enterprises, while at international level Eurostat and United Nations Economic Commission for Europe are the main users. |
|||
12.2. Relevance - User Satisfaction | |||
Transport Section monitors user needs in order to satisfy them. Generally, there is a smooth cooperation, through prompt response to user’s requests. Moreover, ELSTAT conducts a user satisfaction survey every six months. More information about the results of the survey is available at the following link: http://www.statistics.gr/en/user-satisfaction-survey Furthermore, ELSTAT organizes a Users Conference, on an annual basis, in which representatives of private and public sector, educational and research institutions participate. The conferences provide a significant opportunity for ELSTAT to collect comments and suggestions from users relative to the dissemination and the accessibility of the statistical data. Information on the conference is available at the link: |
|||
12.3. Completeness | |||
Maritime transport statistics data provided are in line with the relevant EU Directive. |
|
|||
13.1. Accuracy - overall | |||
Since the survey is a census survey, any non sampling errors (non – response or processing errors) are identified by means of appropriate checks and are duly corrected, in cooperation with the administrative sources and shipping companies involved. In this way, survey produces high accuracy results. Comparing the data with other sources such as data compiled by port organizations, some discrepancies are occurred due to methodological reasons. |
|||
13.2. Sampling error | |||
Not applicable for maritime transport data collection. |
|||
13.3. Non-sampling error | |||
Non – sampling errors, these are mostly due to erroneous filling in the questionnaires by the administrative sources (port authorities and organization of ports) and shipping companies, which are corrected during the production process of data. Coverage error: there is no coverage error |
|
|||
14.1. Timeliness | |||
Quarterly data should be transmitted by Member States to Eurostat within five months of the end of the period of observation; annual data within eight months. The Commission (Eurostat) shall disseminate appropriate statistical data with a periodicity comparable to that of the results transmitted (Directive 2009/42/EC). |
|||
14.2. Punctuality | |||
The publicity of results and the statistical product is usually in time |
|
|||
15.1. Comparability - geographical | |||
The available data are comparable with the respective data of the members of the EU, given that this survey is conducted according to the Directive 2009/42. |
|||
15.2. Comparability - over time | |||
The data are available from 2000 to today. There were no breaks in time series. |
|||
15.3. Coherence - cross domain | |||
There are no relative data from other sources for this survey. Maritime transport statistics are different from those of other transport modes. |
|||
15.4. Coherence - internal | |||
Coherence among variables is compared in all stages of the statistical process. The aggregates are always consistent with their main sub – aggregates. |
|
|||
Regarding the staff of ELSTAT the annual cost has been estimated approximately 165,000 euro’s. Regarding the respondents (port authorities, shipping companies ), it has been not estimated. |
|
|||
17.1. Data revision - policy | |||
The general revision policy adopted for ELSTAT is available at the link: http://www.statistics.gr/en/policies |
|||

|
|||
18.1. Source data | |||
The primary collected data are provided by administrative sources (port authorities, port organizations) and shipping companies. The data are collected from total number of ports of the country. |
|||
18.2. Frequency of data collection | |||
Frequency of data collection is monthly. |
|||
18.3. Data collection | |||
Data are collected through specially designed questionnaires. The questionnaires are sent by post or email and they are collected via post or via email. |
|||
18.4. Data validation | |||
At national level, data processing involves checking the data derived from respondents with the aim of identifying (and eventually correcting) errors. Not all errors can be identified and the aim is to detect the errors that have a significant impact to the results. Data processing also involves checks for completeness, checks to confirm that values are within given ranges and that values for related variables are coherent. Data processing may take place during or after data entry. Responses can be compared with those of previous quarters and years. Inconsistencies or big deviations indicate that further checks are required and may result in further processing. There are also checks conducted by Eurostat in a quarterly and yearly basis. |
|||
18.5. Data compilation | |||
The initial data, once collected, undergo logical checks. Afterwards, data are entered into a database, where they undergo computing, logical and completeness checks. Statistical tables are produced that are also being checked for their consistency and data are compared with them of previous quarters and years. |
|||
18.6. Adjustment | |||
It is not applicable |
