Production data are kept in SAS and stored long term in ASCII format.

The purpose is to measure the Norwegian registered merchant fleet's size and structure. Until 1957 the statistics comprised of all vessels required to be registered according to Norwegian law - that is, all vessels of steam and motor engine of 25 gross tons and above, and sail ships of 50 gross tons and above. The statistics comprised therefore of many vessels not included in the merchant fleet, e.g. all fishing vessels, whale catching vessels and other specialized vessels (towing, rescue and salvage, ice brakers, cabel laying vessels, and so forth) of 25 (for sail ships 50) gross tons. In 1957 all the Nordic countries agreed to limit the merchant fleet to vessels carrying cargo and passengers of 100 gross tons and above.

The statistics are used by National Accounts, governmental departments, shipping enterprises, research institutions and universities. The statistics are also used by individuals with interest in Norwegian shipping.

The register was until 2001 used for collection of data in the survey Domestic Maritime Transportation

Arrivals of vessels at Norwegian and foreign ports is an additional source of information on ships registered in NIS.

The statistics was through the year 2009 based on The Maritime Directorate's control system for Norwegian registered vessels, and included all merchant vessels of 100 gross tons and above for passenger and goods transport. The statistics do not include fishing vessels and special vessels such as towing, rescue and salvage, ice breakers, research/weather/seismic vessels, cable laying vessels, drilling vessels and so forth. Statistics over fish catching vessels are published on Fishing and fish farming

All vessels in NIS and NOR must hold certificates issued by the directorate

Through 2008 data was supplied by The Maritime Directorate who through the control system manages certificates needed for the various types of traffic. All vessels in NIS and NOR must hold certificates issued by the directorate. The data supplied to Statistiscs Norway was based on a criteria of valid main certificate in parts of the year.

Starting with the year of 2009 data is collected directly from Skipsregistrene NIS/NOR. This change in sourcing does not impact the type of vessels included in the merchant fleet.

With the shift to Skipsregistrene NIS/NOR, as data supplier, the requirement of valid main certificate is abandoned.

The statistics is a total count of all Norwegian registered vessels given the limitations described earlier.

With Skipsregistrene NIS/NOR as new data supplier in 2009, all vessels in the registrer can be found in tables of Statbank. Main focus is nevertheless on the merchant fleet.

The situation described in the data is as of 31st of december.

The information on the vessels are transmitted electronically, and are adapted to the computer system in Statistics Norway.

Statistics Norway makes few changes on submitted data beyond checking classification codes. In the event that these are found to be wrong or missing the data supplier is consulted. Tabulated data is compared to previous years.

Data is receieved with the vessel types given by The Maritime Directorate which are coded into the standard used by Statistics Norway

No computations are made beyond those required for aggregate numbers.

The extraction of data from The Norwegian Maritime Directorate control system was altered from 2000 and onwards to include only vessels with valid main certificate.

Starting with 2009, data supplier is Skipsregistrene NIS/NOR. This means that the requirement of a valid main certificate is abandoned.

In May 2011 there were discovered errors in classifications for the posted figures for the years 2007-2009. For the merchant fleet in total the error was limited to two vessels in 2007 and 2008, and eight vessels in 2009. The error affected all categories. Revised figures were posted in Statbank while auxiliary tables in the main posting are left unchanged.

Beginning from 2017, the Norwegian Maritime Directorate (SDIR) decided to categorize "construction ships" as part of the Norwegian merchant fleet. This originally led to a deviation between the figures published by SDIR and Statistics Norway for 2017 by 41 vessels. The deviation was corrected on February 1, 2019.
