            Scott,That makes sense.  You are certainly a member of a very exclusive group.  What is there, maybe 5 operating DSV's out there?  Hank

                    Scott,DNVGL considered my 500ft design as deep diving.Below is there response on this.Alan
No. 500ft is seen as a deep depth, where even tec-divers will have difficulties to reach without special preparations. 
96h additional life support is intended to enable rescue teams to arrive, find and reach the submersible as well to apply means for rescue of the submersible (if e.g. stucked or entangled, the pilot became unconscious, etc.)

I have heard 2 things*2000m or more*Have the ballast use a high pressure pump.
But there isn't a law or anything so I guess anyone could call anything they like. Haha

                    Thanks Carsten,
We actually already have the rules and have been deep deep down the rabbit hole. Haha. There is some wording that does not jive with some of other parts as well as some things we are going to need acceptions on since we are a DSV and not a traditional submarine.
Thank you,Scott Waters

Scott the rules are online : 

https://rules.dnvgl.com/ServiceDocuments/dnvgl/#!/industry/1/Maritime/5/DNV%20GL%20rules%20for%20classification:%20Underwater%20technology%20(RU-UWT)

No need to ask an inspector.

Is there anyone on PSUBS that is familiar with DNVGL rules? We have some basic questions, but are trying not to consult an inspector for every question because of the cost. 

Thank you,
Scott
