Managed by the Norwegian Hydrographic Service, Primar-Stavanger currently distributes more than 15,000 ENCs from over a dozen nations and has recently extended its activities to include digital charts of South Korean waters.

As a result of the agreement, ENC coverage from Denmark, Estonia, Finland, France, Latvia, Norway, Poland and Sweden will now be available as an integral part of the UKHO's Admiralty products. Its ECDIS service, it says, provides global official electronic chart coverage from a single source at a fixed price; new ENCs are automatically included as they become available together with new editions and weekly updates at no additional cost.
