As for SSI, an OWD can dive up to 18 mts depth (60 fsw).
To become AOWD the diver must have at least 24 dives logged in the log book and 4 specialties that qualify for AOWD. One of the specialties that qualify for AOWD is Deep Diving. The specialty Deep Diving allows the diver to dive up to 40 mts depth (130 fsw).
Though there is a special mention in the book that the diver must have some experience to reach that depth.
Besides 40 mts (130 fsw) is considered the limit for Recreational Diving. SSI tables for Recreational Diving are limited to 40 mts.
Again, a SSI AOWD could not have the Deep Diving certification and, in spite of being AOWD, could not dive beyond 18 mts.
