CURRENT STATUS
This is the official website of the Norwegian diving and decompression tables (NDDT). The editor of the webpage is the principal author (Jan Risberg) and you may contacct me through e-mail. The co-authors of NDTT are not responsible for the content of this website except for the official PDF-versions of the NDTT.
The NDTT was issued in its third revision in 2008. The fourth edition was released Jan 15th 2017, the fifth edition was released September 2019 and the sixth edition August 2024.
The third revision was authored by Arne-Johan Arntzen, Svein Eidsvik and Jan Risberg. Arne-Johan Arntzen has decided to withdraw from further participation and Svein Eidsvik regrettably died during summer 2015.
Jan Risberg has been granted the rights from the publisher (Barotech AS) for further development of the tables. Olav Eftedal and Andreas Møllerøkken co-edited the fourth and fifth edition. Olav Eftedal and Geir Gundersen co-edited the sixth edition. The English verion is available for download - please use the link indicated in the far most right part of this webpage.
This site will not update issues related to the third (or earlier) editions of the NDTT. Please contact Jan Risberg as detailed below if you have questions related to earlier editions.

Errors and improvement proposals
The tables will be revised as errors are identified and improvement proposals received. We heartly wellcome comments to the tables through e-mail. A specific page in Norwegian language on this website has been dedicated for presentation of areas under consideration. A similar page is available in English language, but priority is given to keep the Norwegian page updated. Accordingly there may be topics covered on the Norwegian site that is not presented in English language.
