About this website

CURRENT STATUS

 

This is the official website of the Norwegian diving and decompression tables (NDDT).

The NDTT was issued in its third revision in 2008. The fourth edition was released Jan 15th 2017.

 

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 has accepted to co-edit the new revision, A draft version of NDTT Rev 4 was issued in Norwegian language and is available for download at this website.

The revision process

MAIN CHANGES

A detailed change log in Norwegian Language is available for download at this website. Major changes are presented in the file "Revision history/change log" on the right panel of this page. Further revision has taken place since this change log was written (the change log was issued July 2016 while the latest changes were implemented December 2016). We do not have the capacity to translate the Norwegian change log document (for changes implemented after July 2016), however these changes are of a comparatively minor nature. The reader should be aware that though the change log document refers to Revision 6 of the US Navy Diving Manual, the authors have reviewed Rev 7 of the USN Diving Manual and included those changes considered relevant (this was completed during Dec 2017). The most relevant change from USN Diving Manual Rev 6 (2008) to Rev 7 (2016) is the use of VVAL 79 parameter set rather than VVAL18M.
